If you have ideas for the wiki, you can generally just do them, by editing the wiki! In general we would encourage you to be bold, though it may be worth discussing big restructuring.

If you have ideas for technical improvements to the way the wiki works, e.g. extensions we should install, you might add them here. For adding extensions, once discussed and consensus is present, a wiki admin should be requested to add the suggestion as an issue to Blacktocat.svg openstreetmap/operations/issues/. ([1])

Visual editor isn't usable because of {{Fa}} template

By putting the {{fa}} template at beginning of Farsi pages, content of the page will be wrapped into it, and so, Visual editor doesn't allow direct editing, but we should edit the content via an interface like text editor.

I found out if I put direct HTML of the template instead of the template itself, visual editor will work.

An example page that uses the {{fa}} to make the page RTL, and the same page that uses the following HTML directly (HTML code from template):

<div lang="fa" dir="rtl" class="mw-content-rtl" style="direction:rtl;text-align:initial;font-family:'Noto Naskh Arabic',Noto,'Segoe UI','Iranian Sans',Tahoma,sans-serif;font-size:initial;line-height:1.6">

My question: is there any solution to avoid using this long piece of HTML code and at the same time visual editor work properly? iriman (talk) 13:15, 22 May 2019 (UTC)

What formatting and templates (if any) do multilingual WMF wikis such as Wikimedia Commons, and use? Does the Visual editor work there? --Andrew (talk) 19:09, 22 May 2019 (UTC)
seems they don't have visual editor as we have here. It's a translate functionality. but on commons there is some templates, for example main page in persian wikimedia commons has a template that uses langcode parameter, however I couldn't find visual editor. iriman (talk) 13:37, 23 May 2019 (UTC)

I tried out a workaround so that for using it without a parameter we should use <div {{fa}}> instead of bare {{fa}}. Apparently it works. Please take a look at my draft. iriman (talk) 14:22, 23 May 2019 (UTC)

I want to modify {{Fa}} as its sandbox version. Then change all instances of {{fa}} to <div {{fa}}> on all pages of this wiki (~300 pages) with a comment for users who are following those pages.
This will not hurt inline ones {{fa|some text}}, as you can see in my draft mentioned on previous message.
I cannot do this task manually, and willing someone do it automatically.
After that we also need to update {{Ltr}} (~50 pages). iriman (talk) 14:51, 24 May 2019 (UTC)
Regarding your question: WM Commons seems to use the page content language property. According to the MediaWiki documentation, changing the page language wraps the content area in <div lang="xyz" dir="ltr/rtl" class="mw-content-ltr/rtl">page content</div>. So, in this case it would be <div lang="fa" dir="rtl" class="mw-content-rtl">.... This solution looks a bit more professional for me, but it would not necessarily include the additional style definitions by {{Fa}}. Is that an issue? (from a technical POV, we would need to request the system administrators to carry out some configuration changes and it may take a few days to review.) --Tigerfell This user is member of the wiki team of OSM (Let's talk) 18:08, 24 May 2019 (UTC)
There is no Special:PageLanguage here though. --Andrew (talk) 08:44, 25 May 2019 (UTC)
That is what I meant with "configuration changes". First of all, they would need to enable setting languages for individual pages using $wgPageLanguageUseDB and then they need to assign the pagelang permission to some user group. I'd suggest either user or autoconfirmed (most of us are a member of both groups). The special page will then appear. The procedure for changing the page language would then work similar to changing the page content model using Special:ChangeContentModel. BTW, we could save the rest of the markup of {{Fa}} in MediaWiki:Common.css. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 10:57, 25 May 2019 (UTC)
@Tigerfell Definitely your solution is more professional. Font of the page and line height are important but not as important as page direction. With your solution if we'll have visual editor, I think we would be comfortable with it. iriman (talk) 11:24, 25 May 2019 (UTC)

@Iriman: The feature was added in Blacktocat.svg openstreetmap/chef/pull/239. I already tried it out in my sandbox. Regarding the rest of the formatting, I would suggest you make an edit request at MediaWiki talk:Common.css for all RTL languages' formatting. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 20:52, 4 June 2019 (UTC)

Nice! Many thanks for following up on this issue. Ok, I will make a request there, thanks for the link! iriman (talk) 23:39, 4 June 2019 (UTC)
@Yurik: Is it possible to set this for all pages with language prefixes in their names by bot? --Andrew (talk) 06:21, 5 June 2019 (UTC)
Yes, it would be a fairly simple bot that would call action=setpagelanguage, but I am not sure how the bot will know the current language of the page - I couldn't find the api for that. Perhaps the bot will just keep a list of pages it has already modified. --Yurik (talk) 18:46, 5 June 2019 (UTC)
All pages except for those changed recently (after the configuration change) are in English (default language for this wiki). --Tigerfell This user is member of the wiki team of OSM (Let's talk) 20:10, 5 June 2019 (UTC)
+1. Also we need to remove {{Fa}}, {{Ar}}, etc. from beginning of those pages. But note that there may be some of these templates currently explicitly transcluded in block mode {{fa}}...</div> or inline mode {{fa|...}}. They should remain as they are now. iriman (talk) 19:01, 5 June 2019 (UTC)
Actually currently we may have {{fa}}...</div> or inline mode {{fa|...}} in other namespaces that are ltr. not an issue here. iriman (talk) 08:16, 6 June 2019 (UTC)
Long term maintenance could be done various ways, for instance putting a warning message and tracking category in the language template if the language set in Mediawiki differs from the one inferred from the page name. Populating the language tags in the first place is the tedious bit. --Andrew (talk) 07:36, 6 June 2019 (UTC)
Why do we need to have the correct language setting for all pages? It would be obviously nice to know and a good info for search engines and the like, but apart from that? --Tigerfell This user is member of the wiki team of OSM (Let's talk) 17:23, 6 June 2019 (UTC)
It could be useful for language-specific formatting, for example font face (since it's a common need between all languages). This is a possibility only. Users of a language may need it, or not if default configuratuon satisfies them. For Fa, Ar, He, etc. currently we have font settings on our templates {{fa}}, {{ar}}, {{he}}, etc.iriman (talk) 10:59, 8 June 2019 (UTC)

By use of @Wynndale: idea, I put a general notice on {{Fa}} template for a somehow long term maintenance on Farsi wiki. iriman (talk) 15:21, 13 June 2019 (UTC)

Hi again, could someone please take this issue in hand: Setting the page content language for new wiki pages automatically on page creation iriman (talk) 05:51, 17 June 2019 (UTC)

Transition to use data items when this can be done without loosing information

Hi I have experienced an editor who claims that we have not decided to start using the data items. In this edit the user reverted my edit resulting in a net loss of information because the data item have a lot more combinations: combination: shelter_type bench table drinking_water water_source floor:material building access image fireplace mattress locked distance_from_road year_of_construction water_source bin wikidata capacity

I therefore suggest that we discuss here and later vote about start using the data of our fantastic data items when no data is lost doing so as in the example case above.--PangoSE (talk) 10:56, 15 January 2020 (UTC)

This specific case is a separate issue, for example distance_from_road=* seems to be dubious at best and in my opinion it should not be used at all. I will start a discussion on the tagging mailing list to get wider opinions Mateusz Konieczny (talk) 11:08, 15 January 2020 (UTC)
No, you did not mention this at all in you revert. You also did not discuss this in the talk page of either the tag in question nor the discussion page of the data item.--PangoSE (talk) 11:18, 15 January 2020 (UTC)
Yes, initial revert was done with justification "relying on fetch data from wikidata data items is not desirable". I am disputing claim that it resulted in "net loss of information". I will add further comments about what I consider as mistakes on Item talk:Q5007 (starting from wikidata and image tags). Mateusz Konieczny (talk) 11:27, 15 January 2020 (UTC)
For what it's worth, I was also going to revert the change, but I see Mateusz Konieczny got to it before me. --Jeisenbe (talk) 13:33, 15 January 2020 (UTC)
Also I'm not in favor of fragmentating the discussion away from this wiki. Please urge wherever you share this that they contribute here.--PangoSE (talk) 11:20, 15 January 2020 (UTC)
Certainly, any external notification should mention that it is 100% invitation and that comments elsewhere are going to be ignored. Mateusz Konieczny (talk) 11:24, 15 January 2020 (UTC)
For more general issue - I have several problems with data items. Main ones for me are
  • Adding data item to the Watchlist means that it gets filled with "used added translation in Hungarian/Korean/etc" or in other language that is 100% unfamiliar to me where I am unable to distinguish correct edit from clear vandalism, AFAIK it is impossible to avoid it and makes easy to miss edits that I can review
  • Watchlist is filled with things like Item talk:Q5007‎‎. I really prefer to not use database identifiers as titles, especially in cases where obvious human-rememberable titles are available
  • As a direct result of watchlist issues - quality of data in data items is significantly lower than data specified in the article text (including template parameters)
  • poor page titles (compare Item:Q5007 and Tag:amenity=shelter), naming collision with the main Wikidata (see )
  • Editing interface requires JS, page loads for far longer and interface elements jump around as page continues to load
  • Inability to copy content, edit it outside browser as text and copy it back
  • Tying OSM Wiki to one more third-party system and relying on it, one more part that may break
  • Making editing Wiki more complex, now people need to edit in two different places
  • Overall, due to UI issues I am not a fan of data items and oppose migrating to them
Mateusz Konieczny (talk) 11:24, 15 January 2020 (UTC)
Thanks for taking the time to write this. I like your arguments and I'm somewhat surprised that we have rolled out a system and encourage people to used it but when they do, the community cannot accept the information to be displayed in the wiki.--PangoSE (talk) 15:02, 15 January 2020 (UTC)
PangoSE I'm very unhappy with changes you made. Some tools use wiki and not data items (for ex taginfo). Removing stuff from wiki destroy usefull information for those tools. Keeping it in the wiki without editing the data item allow all info to be used by both wiki-based and dataitems-based tools.
in fact I'm unhappy with the write acces to data items that has been done too early, all major tools must first be migrated to the dataitems.
unfortunately for the moment the data items lead to a desyncronization of the information according to the method used to access it, which is the opposite of the arguments used for the experiments.
Marc marc (talk) 12:03, 15 January 2020 (UTC)
Hi Marc, based on the other answers here, maybe the data items should as you suggest be read-only until wider adoption is agreed. Personally I would rather transition to a wikibase-only solution parsed from the wiki and the wiki deprecated, instead of this half-half solution that is brittle/confusing/not agreed on. I like the wikibase-editing approach and consistency better, but this is my subjective taste.--PangoSE (talk) 15:02, 15 January 2020 (UTC)
I also oppose this idea. Editing the data items is more difficult than adding the text-based templates and maintenance is harder. It is nearly impossible to follow the changes to a data item, because each change is recorded separately. Right now you can understand the whole history of a Tag: or Key: page, which describe the basic features in Openstreetmap, just by looking at the page history. If we instead switch to pull everything from the wiki data item, you will have to look at 2 pages histories to understand what has happened. I don't see any benefits to outweigh these problems, especially for the English language pages. --Jeisenbe (talk) 13:33, 15 January 2020 (UTC)
I disagree that it is harder than templates and text - I personally dislike wiki-templates if the data is suitable to model in a wikibase instead (which it is in this case IMO). This is the reason I edited the combination-property on the item instead of the wiki-infobox, I remind you that I saw nothing anywhere discouraging me from doing this. I agree that having both side by side is confusing and not a good idea. Wikipedia and Wikidata work because they are not side by side and it is quite clearly define what goes where. It seems we don't have the contributor base or manpower to succeed in copying this WMF wikidata-way at the moment and the result is bad. What about uninstalling the wikibase from the wiki and create a wholly separate OSMbase website where the bot can run loose and whoever want can contribute? This would as I see it solve all the problems in one go: no more confusion, no more editing items instead of wiki and we can choose to copy information from the OSMbase site if we want to and reference properly.--PangoSE (talk) 15:02, 15 January 2020 (UTC)
I agree with Mateusz and Jeisenbe, the complexity added with the wikidata items makes it harder to understand what is going on, and while I follow quite some wikipages with respect to their changes, I do not do it for our wikidata items because of too much noise. —Dieterdreist (talk) 18:49, 15 January 2020 (UTC)

@Mateusz Konieczny: I appreciate you spelling out in detail the pain points you're experiencing with data items. I hope we can chip away at these problems without making data items read-only or shunting them onto a less integrated site, so that OSM can continue to benefit from increased software integration (that isn't bottlenecked by taginfo) and improved translation coverage.

I think I misunderstood you the other day when you asked how to filter your watchlist in Slack. Here are some possible solutions to the noise that you're experiencing on Special:Watchlist. These solutions also work equally well on Special:RecentChanges and Special:RecentChangesLinked:

  • To filter out changes to data items associated with the wiki pages you're watching, uncheck the "Show data item edits in your watchlist" setting in your watchlist preferences. (The watchlist page itself also has a checkbox in the "Filter changes" dropdown to filter them out temporarily.) The checkbox was misleadingly labeled "Show OpenStreetMap Wiki edits in your watchlist" until just now. There are many such messages that refer to the {{WBREPONAME}} variable. I've fixed all the messages I could find, but only in English. This GitHub issue tracks changing the MediaWiki configuration to resolve the ambiguity across all languages.
  • To filter out all edits to data items, click the  Namespaces button in the filter panel, check "Item", and click "Exclude selected". You can click the bookmark button to save the filters for next time.
  • To filter out only changes to labels, descriptions, or aliases on data items, click the  Tags button in the filter panel, check "Data item terms", and click "Exclude selected". You can click the bookmark button to save the filters for next time. I just set up an "abuse filter" to automatically tag incoming edits going forward. (Edit: This filter is temporarily disabled due to a configuration issue.)
  • If you need to track edits to descriptions in a particular language but not the other languages, I could create a dedicated abuse filter for your language, but we should limit such tags to the most widely used languages to avoid unnecessary load on the server. That said, I hope the existing filter and tag are enough for your needs; to me, an inability to filter on specific languages would be similar to the situation with translatable templates.

@Yurik: has been working on some enhancements to this wiki's interface that will integrate data item editing into the main wiki reading interface. That should result in more intuitive editing than the existing template system without the excessive clicking that the default Wikibase interface currently requires.

I think it's fair to say that editing either the wiki pages or the data items is still too confusing to inexperienced wiki editors (which is to say, inexperienced and experienced mappers alike). I value data items but also think we should make sure they coexist with key/tag description pages for now, rather than coopting them. Data redundancy isn't ideal, but we already flag some inconsistencies through maintenance categories such as Category:Mismatched onNode. If these inconsistencies become too overwhelming to resolve manually, we could have bots like Yurikbot do the gruntwork of automatically synchronizing the data items with pages or vice versa. This kind of synchronization is impractical if we rely solely on wiki pages and translations of wiki pages, as evidenced by the 1,278 keys and tags that are documented inconsistently among wikitext translations.

I would want to ability to exclude from watchlist edits for labels, except specified languages (Polish and English in my case). Weird setups like filtering RSS or abuse filters are not really solving the root problem with watchlist. Note that watchlist pollution affects everybody, not just me and this is a basic tool in wiki. Solution to this problem should be accessible to normal users. Mateusz Konieczny (talk) 19:15, 16 January 2020 (UTC)

I agree, we can do more to improve the ergonomics. Using abuse filters in the manner described above is not uncommon with MediaWiki instances, but it does require some adjustments to the default configuration.

At a certain point of granularity, we’re really talking about the ability to query changes based on arbitrary criteria, which is beyond MediaWiki’s built-in capabilities regardless of the page’s content model. Such querying is relatively straightforward with tools like Quarry. But if the primary requirement is that the tooling is 100% built into MediaWiki, then there’s no good workaround for the fact that translations live on the same page as each other. This same limitation applies to various templates around here, to the extent that anyone cares to watch templates.

On the other hand, keeping translations together means they’re less likely to get out of sync, and sharing untranslatable properties among translators keeps our tagging system from fragmenting between language communities. If hypothetically we were to abandon data items, we would still need a solution for these problems. But an alternative translation solution, the Translate extension, has gone nowhere. Meanwhile, if we were to require that every key/tag infobox draws its data from a shared template instead, I’m not sure that would be any more ergonomic, except for the few of us who are comfortable hacking on templates. (As it is, even the infobox parameters being discussed above require plenty of clicking around in the visual editor, which is enabled by default.)

This is also a good opportunity to examine the practical problems with relying on non-core tools. (I hesitate to call something run entirely by OSM contributors, often on OSM infrastructure, “third-party”.) If filtering the watchlist were to require a user script or potentially a lightweight tool that uses the MediaWiki API, would that be any more unusual than our reliance on taginfo for analyzing OSM tag usage or OSMCha for supplementing the OSM website’s changeset history functionality?

If the concern is about learning curve and discoverability for new contributors, then the solution is to embed these tools in the wiki, which we can do by writing gadgets. If the concern is that only a limited subset of the mapping community has the wherewithal to contribute to data items or tooling around them, then I would just take a look at the limited number of people who maintain our templates today as a counterpoint. The power of a wiki is its openness to new contributors being bold with new ideas, but that flexibility has long been hamstrung by concerns about compatibility with screen scrapers used by taginfo and OSMBC, neither of which are actively maintained, making it difficult to revamp poorly architected templates.

I think the ultimate goal should be that every mapper should be able to improve our documentation and shape the community’s understanding of our tagging system without having to learn a foreign language (human or computer). None of our schemes accomplishes that, not even close. But a system that has localization and programmatic access built in is far superior to a system that can only be localized or parsed thanks to layers of templating hacks and unmaintained regular expressions.

Finally, since Gmane is down and I can’t respond directly to the mailing list thread about this discussion, it should be noted that data items are an approach to managing documentation about tags; its adoption is completely orthogonal to the inclusion of Wikidata QIDs in the OSM database.

Re: "...[it] keeps our tagging system from fragmenting between language communities. If hypothetically we were to abandon data items, we would still need a solution" - this is assuming that allowing tags to be used differently in other countries and language communities is a problem that must be stamped out, rather than a normal result of a global project which is adapted to local conditions in many different countries and language areas.
The watchlist is currently an automatic way of maintaining the wiki pages: anyone who edits a page is signed up to get notifications about any changes that happen. That's why I am watching almost all of the Tag: and Key: pages listed in Map Features: I have edited most of them at one time or another, and I now am aware if they are changed. There are a dozen other users that are being notified of each change for the same reason, and this prevents vandalism and mistakes. But watching the wiki data items is nearly impossible: there are far too many email notifications to manage as less than a full-time job, since every individual change in every language is a notification.
Re: "I think the ultimate goal should be that every mapper should be able to improve our documentation and shape the community’s understanding of our tagging system without having to learn a foreign language (human or computer)" - in this case we should remove the ability to directly edit wiki data items and use get things like the "combinations=", "see also=", "requires=" and "onNode, onArea" from the plain text of the wiki page by using a natural language parser. This could still use the wiki data items as a back-end, but it should be designed in a way that does not require any maintenance. Perhaps it is better if tools like taginfo can do this step automatically. I don't know if algorithmic language processing is anywhere near good enough for this purpose, but the goal should be encouraging human-readable, well-written wiki page text (plus some relevant images). All of this data item distraction is taking up time that could be used improving the human-written, human-readable documentation that should be in the main text of the wiki pages, not in a secondary database. --Jeisenbe (talk) 02:46, 17 January 2020 (UTC)

Ignoring its potential to the wider OSM project beyond the wiki, Wikibase is a tool for managing the content of infoboxes. Just as infoboxes aren't a replacement for body text, data items aren't a replacement for body text either. As things stand, everything in a data item should already be shown in the key or tag description page's infobox. Eventually, I hope you'll be even able to click a edit button next to each row in the infobox, type the new value inline, and save without ever leaving the page. But there will always be a place for human-written, human-readable documentation regardless of data items. The body text is a great place to explain the real-world phenomenon expressed by the tag, how to find such things on foot or in imagery, common mistakes to avoid and how to fix them, external resources for learning more about the topic, and so on. For example, very little of the body text in Tag:emergency=siren or Tag:service=driveway overlaps with the infoboxes.

Some variability is inevitable and preferable in such a global yet hyperlocal project as OSM. However, most of the interlanguage discrepancies on this wiki are unintentional. (This list links to items for which inconsistencies were identified when seeding the original data items with data parsed from key and tag description pages and their translations, minus the inconsistencies that have since been resolved thanks to the data items bringing them to light.) Indeed, the few intentional differences seem to conflate languages with countries. The rest are symptoms of the decentralized management of infobox data – inconsistencies that are just as problematic to mappers as they are to any validator, editor, or data consumer that would be built upon the wiki's documentation. After all, most people who edit an infobox won't think to synchronize all the other languages' infoboxes. In the days before Wikibase, someone might've proposed that the infobox in Tag:amenity=telephone and all its translations be populated by the contents of a shared Template:Tag:amenity=telephone. Then maybe someone would've proposed a boilerplate template you could fill out, and then localized versions of that boilerplate template. Wikibase formalizes this functionality for all tags without the overhead of countless error-prone templates.

I'm a bit puzzled by your suggestion about natural language processing. My point was that Wikibase and the data items' properties are already fully localizable, and many languages now enjoy translated tag descriptions in iD because the barrier to creating a translation is so low compared to standard wiki pages. If the problem is that this Wikibase installation is half-baked in any way, yet-to-be-written NLP software isn't a solution. Nor is less sophisticated screen scraping: there's no point to a freeform, human-readable wiki page if it has to be formulated a certain way for a parser to pick it up. Anyways, no one is suggesting that body text be generated from data items, only that the infoboxes draw from data items (which are fully localized) instead of template parameters (which require not only English language skills but also potentially wikitext skills). Even then, I would caution that there's no need to rush and remove template parameters until the tooling around editing and watching data items becomes more mature.

@Jeisenbe: I take it that you enabled the "Email me when a page or a file on my watchlist is changed" and "Add pages and files I edit to my watchlist" preferences? If you're receiving e-mail about every granular change to a data item, I can definitely understand that frustration. Have you considered disabling watchlist e-mails in favor of Special:Watchlist, which can group repeated changes to the same page or data item (as long as you keep "Use non-JavaScript interface" disabled)? I'm currently watching about 500 data items, but the automatic grouping keeps the noise down, and I'm trying to get the translation filter back up and running. If you prefer e-mail or a feed reader, perhaps you could configure your client to filter out notifications about data items. – Minh Nguyễn 💬 06:46, 17 January 2020 (UTC)
"Have you considered disabling watchlist e-mails in favor of Special:Watchlist, which can group repeated changes to the same page or data item (as long as you keep "Use non-JavaScript interface" disabled)?" - I am using solely Special:Watchlist and it is also not capable of handling data items (unable to exclude translation edits in languages that are unfamiliar to me and show other edits). I am unable to keep them on watchlist as label-translation edits to them lead to an unreasonable spam. I never used email notifications Mateusz Konieczny (talk) 10:22, 17 January 2020 (UTC)

Hi @PangoSE: and thank you to have started this discussion. It seems we'll have to discuss, contribute and wait a bit more before DataItems be adopted as wide as wiki is currently in a large variety of tools. WikiData, DataItems, @Yurik: and other contributors works bring here a lot to samentical information quality and benefits will surely be far more important than preserving wikicode edition on a long term basis. As few concerns raise about how such tools are deserving mappers comunity, I find myself each time more surprised on how changes are first of all critisized and pretty not understood. As a wikieditor I just can't wait for a better DataItem integration in as many tool as possible. For instance, it's currently under discussion with JOSM team to take the good of this solution to produce useful and translated presets. Let's keep going with this good work and positive feelings. Fanfouer (talk) 20:00, 15 January 2020 (UTC)

I never liked the "Wikibase" related changes to our wiki and felt this was driving things away from a relatively simple schema accessible to everyone, into an expert-only realm that required much more domain knowledge to actually make a change. I do not want wiki editing to be (even) more complex than mapping is; most steps in the "Wikibase" direction seemed to me to complicate things, or at least rely on some experts to make some things available that are easy to use (but if you want something else it's template madness). I usually kept quiet because I didn't want to ruin the fun for the Wikibase advocates as long as the "normal" use of the Wiki was not hindered too much, but if people start treating the "Wikibase" part as the master system and everything else as "derived content", and you are forced to understand the "Wikibase" stuff to participate, then the buck stops for me and I am in favour of throwing out the lot. --Woodpeck (talk) 14:51, 17 January 2020 (UTC)

Same remarks apply to wikicode and templates. It is retricted to a small community mastering the edition of wikicode to change anything. Let's call it the OSM community. Fanfouer (talk) 16:05, 17 January 2020 (UTC)
I agree with Fanfouer here. I think much of this discussion is based on an unmerited bias towards wikicode. Lets face the facts:
  1. wikicode as technology is +20 years old and besides adding Lua not much has changed
  2. Wikicode might look pretty but it is notoriously hard to parse and a bad choice if that is your top priority
  3. Wikibase is a fairly new technology with much improved data consistency and interoperability.
  4. wikibase items can be improved from e.g. inside josm if we would like that
  5. improvements to the documentation in items reach everyone, improvements in the wiki might only reach a minority understanding that language
I have the impression that with well documented items with qualifiers - I'm not so sure we need the body text anymore to explain use of tags. People in doubt can ask on a mailing list or on the talk page of an item. This might cause a steeped learning curve, or might not because the presets in both josm and ID are very nice and helpful and ease my memory so that I font have to remember a lot of tags. With data items we can have a mouse over popup that defines any tag the user sees on the screen. This is wonderful!--PangoSE (talk) 21:19, 17 January 2020 (UTC)
  1. "not much has changed" - I consider it as a strong benefit. It means that there is much larger pool of people familiar with it. Old technologies are often worse than new technologies, but "X is an old technology, without breaking changes for a long time, familiar to many" is a strength, not a weakness
  2. easy to edit, hard to parse - again, I consider this tradeoff as a strength. OSM Wiki is already hard to edit. Making it even harder, just to make parsing of data easier seems a bad change. Especially as data in the infobox templates is parseable and is already used, for example in taginfo!
  3. I agree that keeping data in one place rather than in several is an improvement. But I am not convinced that it is so significant to make data items net positive.
  4. Why we would want to allow editing summary of the article (template parameters/data items) without looking at the article? It will just encourage mismatch between article text and article summary
  5. Can you give an example of some data item that without translation gives useful info? More than image + usage on way/node/area/relation + in use/de facto/deprecated/approved status already displayed by an infobox? I would expect that it is not enough to understand or use the tag.
I am pretty sure that qualifiers are not enough to replace entire article text, though it could be interesting to see this in action. Can you give examples of some complicated tag documentation article and its full replacement in the data item?

@Jeisenbe: -- RE: "Re: "...[it] keeps our tagging system from fragmenting between language communities. If hypothetically we were to abandon data items, we would still need a solution" - this is assuming that allowing tags to be used differently in other countries and language communities is a problem that must be stamped out, rather than a normal result of a global project which is adapted to local conditions in many different countries and language areas.
You are equating regions and languages. The language of the wiki should not be the deciding factor of what should be used where. I could be a Russian-speaking person living in Brooklyn/New York (huge community there, with older generation not speaking any English), or Russia (many different locales), or any other place. Portuguese is spoken in Portugal and Brazil - very different mapping communities. Regions on the other hand could have different rules. But those differences must be documented, hopefully in every language, to make sure everyone understands them including all the data consumers. So far I only know of one case like this -- Key:noexit is allowed on ways, but DE:Key:noexit prohibits it. Most other cases are the result of stale documentation - thus a huge documentation problem. Please see storing geographical differences and the following section about locales. --Yurik (talk) 05:04, 19 January 2020 (UTC)

I find myself disagreeing both with those who want to abandon data items and with those who want to abandon ordinary prose on wiki pages. I think we're all going to talk past each other ad nauseam if we only consider extreme measures. On the one hand, it's ironic that that we're mappers who spend much of our time literally making the world machine-readable through tags, yet we can't accept some structured metadata as a complement to our tag documentation. On the other hand, anyone who thinks we can replace prose mapping documentation with data items should click on Special:RandomInCategory/Tag descriptions a bunch of times and try porting all the body text to the corresponding data item – I think you'll be mired in proposing new properties and qualifiers in Talk:Data items for some time to come.

The issue of unintentional discrepancies between infobox translations is actually a significant problem. If the wiki is internally inconsistent on basic facts like whether a particular tag can be used on an area – in hundreds of cases – can validator and editor developers trust the wiki? Or will they be forced to march to their own tune and bring mappers along with them? Wikibase carries the potential to make the wiki more relevant and harder for tool developers to ignore. Isn't that good for the wiki? But imagining that Wikibase had never been installed, would you favor factoring out each English tag description page's infobox code into a template such as Template:ValueDescription/amenity=telephone, to centralize language-agnostic details like |onArea = and |implies =? What about the English template and parameter names – would we rename the parameters to be panlingual or insert comments in every language? Or should everyone learn English in order to contribute to the infoboxes?

The guide for creating a translation of a tag description page is full of wiki jargon and glosses over lots of things that make it difficult to understand the text that one would be copy-pasting. The Wikibase interface also uses some jargon like "statement" and "qualifier", but all those terms are translated, and a translator doesn't have to bother with anything but the description anyways. It's little wonder that, for instance, there are 1,538 feature description pages in Polish but 2,017 data item descriptions in the same language. (It's even more pronounced in other languages: 41 times more descriptions than pages in Vietnamese.) I look forward to the Polish community eventually writing up full-fledged mapping how-tos for the remaining 479 data items and any others that get Polish descriptions in the meantime, but let's not make perfect the enemy of the good.

Taginfo has been brought up many times in this discussion, but it rather proves the point that this wiki needs structured metadata. Taginfo's wiki scraper is quite involved, but it can't deal with slight variations in wiki syntax or the annotated lists of valid values or related tags that often appear in the page body. [2][3] Validators can't use the taginfo API to flag usage of deprecated tags, so every editor has its own logic. [4] I don't mean to disparage taginfo: its specialty is analyzing the OSM database, not making the wiki more digestible. But the scraper does keep us from modernizing templates like {{ValueDescription}}. We can't for instance remove the redundant "File:" from |image = and |osmcarto-rendering-area = or automatically derive |key = and |value = from the page title without having to also hack on Ruby code.

@Mateusz Konieczny: You might see the constant hum of data item changes in your watchlist as nothing more than noise, but to me it's evidence that the wiki is growing beyond what it was before, becoming more relevant to a larger swath of the OSM community. I feel bad saying you have to put up with daily inconveniences for the sake of this growth. As an administrator, I view it as my responsibility to collaborate on solutions for the inconveniences you're experiencing. Your claim that data items are more difficult to edit than infobox templates is intriguing. So far, all I can surmise is that there's a lot more clicking, and that you need to keep other tabs open for context while you edit the data item. If these or other usability problems have soured you on Wikibase, then we should explore each of those problems, perhaps in new sections of Talk:Data items where the focus can be on improvement rather than elimination.

(Sorry for not responding to each of your above bullet points one by one. It's difficult to do so in this talk page format. In my opinion, the mailing list would've been a less confusing place to quote and reply.)

 – Minh Nguyễn 💬 07:03, 19 January 2020 (UTC)

"wiki is growing beyond what it was before" the difference is that with wiki pages I am intentionally not watchlisting for example German translation page. Data items are forcing me to watchlist all translations. That is why I am using Special:Watchlist, not Special:RecentChanges, Maybe data items have overall better UI and people prefer structured interface. Even at cost of horribly long loading time and slower editing speed. But is there any evidence that data items are overall more accessible or used more? Mateusz Konieczny (talk) 14:54, 21 January 2020 (UTC)
"So far, all I can surmise is that there's a lot more clicking, and that you need to keep other tabs open for context while you edit the data item." - horrible load time, each change must be saved separately, changes now require editing both description and a completely separate page Mateusz Konieczny (talk) 14:54, 21 January 2020 (UTC)
"the mailing list would've been a less confusing place to quote and reply" - I am not going to defend talk page interfaces in mediawiki, this is a clearly horrible hack that really deserves to be replaced. Though for OSM Wiki specific discussing it on Wiki seems a much better idea that using a separate forum like mailing list. Mateusz Konieczny (talk) 14:54, 21 January 2020 (UTC)

Data items - displaying P16 in Wiki lists

More and more data items are translated in other languages (e.g. German). Due to the translation of the label it is difficult to recognize the nativekey behind it in the Wiki, at least working in the Wiki is no longer comfortable. This is especially true for special pages like "Recent changes" or "Watchlist". Therefore I would like to see that these pages in the Wiki always show or list the permanent key P16 instead of the label in the respective display language. - Is there any way to change this? Where would I have to ask this? In the meantime, the only solution is to change the display language to English. Regards --Chris2map (talk) 16:16, 5 June 2020 (UTC)

What you mean by nativekey and P16? (in my case "solution" is to not add data items to watchlist and treat them as separate project, unrelated to real OSM Wiki - though it would not help if someone wants to have data items on a watchlist) Mateusz Konieczny (talk) 16:40, 5 June 2020 (UTC)
You could move the labels of the items concerned to be aliases instead. @Yurik: Any other ideas? --Andrew (talk) 16:54, 5 June 2020 (UTC)
OK I could ignore data items and exclude the namespace :item from watchlist. But if we gonna ignore them, who cares (maintains) about them? - Don't get me wrong. I'm not keen on it. - I think a further separation of the data items from the Wiki must be avoided. Otherwise there will be 2 competing wikis for OpenStreetMap and it is not clear anymore which one will apply. So improving integration or wiping away data items. --Chris (Chris2map (talk) 18:21, 5 June 2020 (UTC))

disagreement in the community about data items and tag pages: how to proceed?

Recently I observed an edit war starting in Tag:highway=living_street, where some lines in the ValueDescription template were repeatedly removed and re-added to start/stop the use of data items for this tag, and one user proceeding to delete the data item itself. For the moment I have locked the page and data item before this gets out of hand any further.
I have commented on Talk:Tag:highway=living street and asked for more cooperation instead of more confrontation, but as the disagreement is not about that tag page itself but the use of data items in general, the discussion really should be on this page here.
I'm putting this here in the hope that we as a community are able to find a better solution than an edit war. --Lyx (talk) 22:07, 23 May 2021 (UTC)

In my opinion, given that there is no consensus to start blanking infoboxes doing this is not OK. At least on English language pages, not sure about translations. Mateusz Konieczny (talk) 08:02, 24 May 2021 (UTC)
This is mainly about translations and giving access to the same level of information to non-english mappers. If you only consider English then sure Data Items make a bit less sense, but please think about non-english speaking viewers. --Gileri (talk) 08:22, 24 May 2021 (UTC)
Also, please see Talk:Tag:highway=living_street#Blanking_infobox, Talk:Tag:highway=living_street#How_can_a_tag_imply_a_key.3F and Talk:Tag:highway=living_street#Conflict_about_.22info_boxes.22 for arguments already made about this issue. --Gileri (talk) 08:09, 24 May 2021 (UTC)

I also think we do need here a procedure in general. At the moment there is a duplicity of content. IMHO this could only be accepted if at first it was clearly defined what is the master content an at second the content would be automated copied/transferred from master to the other data. For all other cases we should eliminate duplicity. At a technical view it is cool that infoboxes can handle both sources of content (wiki page and data items). But here we have the issue that it is not decided which twin is preferred.
I think I understood data items are an extended offer to software and consumers. By having that database of data items there must be a way to check and maintain them in the wiki. So the infoboxes seem the logical place for showing the content of data items and provide the link to edit them. From my view there are some major disabilities or missing features to be fixed, before immediately and completely change to data items in infoboxes:
1. The fixed native key/tag name of an item must show up in lists like recent changes and watchlist (not the label which might be translated).
2. The human readable name of an item must show up in email notification of a watched item (not only the item number).
3. There should be the ability of an edit comment to edits in data items.
If these points are solved it would be fine to me exlusively use data items for content in infoboxes and remove them at the wiki page.
With that step we'll have to decide, which rows or parameters in infoxboxes should "move" to data items. There are ones being predestinated for data items (like "use on nodes/ways/...", status and image). Others like the short "description" might be also a good idea. With "requires", "implies" and "see also" it is more complex. The topics of a key/tag like "requires", "implies" and "see also" might be better placed and treeted at the wiki page, due to having more flexibility to describe them.
We should think about to limit (and maybe reduce) the content of the infobox. It is developed as a short information on a key/tag and never could cover all content. The same applies to data items. So instead of struggling with pressing more and more information in data items, IMHO we should limit it for now to have a well working short content database and first define the use in the wiki and remove duplicity. E.g. by moving "image", "description", "status" and "use on..." completely to data items.
What would be the procedure to proceed? Some kind of proposal? By the way, the continuation of the discussion is hard to find cause it doesn't show up in TOC. regards --Chris2map (talk) 10:34, 24 May 2021 (UTC)

Thank you for you detailed input Chris2map !
I agree that the points you raise makes moderation/review harder. Do you think that having a readable watchlist/log/comments (metadata) are more important than having up-to-date content ? Also a big advantage of Data Items is that one can see edits on the one Data Item "page" instead of in each of 10+ languages, which they most probably can't understand the language for most of them. So those advantages may offset the problems you pointed out. --Gileri (talk) 20:20, 29 May 2021 (UTC)
The maintaining abilities aren't more important than the content. Nevertheless those are important to handle with the content and keep it right and up-to-date. But the underlying issue is how to switch to data items as base for the content of the infobox. Up to now the valid content is the one on wiki page and data item is only determined to be an extension with (automatically) copied data from wiki page. There has to be defined and described what changes are going to be made and how to manage the content data in future. Then it will affect all pages and there must be checked and decided for each page and item, if item data matches the actual page content, before switching infobox. Otherwise content showed on mismatching wiki pages would change at one swoop, even without a note in page history. So maybe it must begin step by step and could be started with the "description", the more so as "description" in data items is already being used by iD editor. I agree that editing the parameters in different languages is more forward at items than at wiki pages. --Chris2map (talk) 22:22, 29 May 2021 (UTC)
Okay, so if I understand you correctly you oppose a global change to infobox in one swoop. What I did, and what the conflict is about, is changing one or two infoboxes attributes to use Data Items, after manual verification that the content is up-to-date.
Also, you indicate that moderation issues makes it hard to follow Data Item changes. But currently one has to follow both Data Items and each and every language version of the tag page if they want to make sure there are no errors. After using Data Items, that makes a lot less content to follow, so that is a net gain, even with the current issues. --Gileri (talk) 09:12, 30 May 2021 (UTC)
Hi, I don't refer to the initiating conflict. My request is what global solutions are there and how to get there (to dissolve duplicity of content data). I'm still open with my position. Actually I would be glad if we could move "description", "use on..." and "status" to data items, and could maintain them in one place. But I think if we (two) do this simply in one swoop by changing templates of infoboxes, there would occure at least 3 problems popping up: 1st) An outcry of part of the community. 2nd) How to ensure that the more up-to-date data has been adopted (if there are discrepancies between wiki and item, as I mentioned above). 3rd) How should the data or parameters be deleted from the wiki pages? So I'm definitely in favor of improving the current situation. Hence my consideration of whether a small step is somehow practical. Do you have an idea for a bigger swoop? --Chris2map (talk) 11:25, 30 May 2021 (UTC)
I don't have ideas to change every infobox at once. Even if I did, based on the resistance on some vocal users for the tiny change I did, I think such an endeavor is bound to fail, sadly. But I would be glad someone with more time and energy on the issue found a way to both solve the technical issues, and convincing that structured data in the wiki for OSM, a structured data project, is a good thing. --Gileri (talk) 11:37, 30 May 2021 (UTC)
Couldn't an update to the template with a check for correct data duplication with warning or error messaging be a solution ? The new infobox would display the wikidata item if it would fits the infobox content from the wiki page. If there is inconsistencies, or wikidata is non existent both values could be displayed in the infobox and the infobox template could generate a "clean-up" or "warning" ambox or a category as you like. This would allow for a gradual transition, a new global changed infobox template but for all at once, as data inconsistencies are clearly displayed and the amboxes or category can be used to trace data duplication errors. Even after a transitional period, I expect that many wiki editors will not feel familiar enough with wikidata to edit it whenever a tagging addition or change is eminent. So the "transitional" template might as well work as a permanent solution and provide more efficient tracking tools for data duplication. --Bert Araali (talk) 12:32, 30 May 2021 (UTC)
"This would allow for a gradual transition" - what should be done only if there is a clear support for such transition. ""clean-up" or "warning" ambox or a category as you like" - such categories exist already, see Category:Mismatched wikidata, Category:Mismatched onArea etc. Mateusz Konieczny (talk) 11:39, 31 May 2021 (UTC)
What I am missing in this discussion so far are ideas - by those opposed to the use of data items and of course others as well - how to make sure that mappers who do not speak English can participate in OSM. In other words, how do we keep documentation consistent about language versions. And if the idea is "Someone monitors changes and adapts the existing translations" I would like to know who that "Someone" is and if "Someone" agrees to take the job. --Lyx (talk) 15:36, 31 May 2021 (UTC)
Actually, for keeping translation in synch data items are worse than OSM Wiki pages. There is no effective way to notice that something is changed (as watchlisting data items fills watchlist with translation updates in all languages, including ones where you cannot review changes). That is why I am against blanking infoboxes, it would Watchlisting wiki page in your language and in English is right now the best solution. And for parameters in infoboxes like onArea - I would be happy to generate list of mismatches if anyone would be interested and keep it up to date. If anyone actually interested in fixing such mismatches - which language is interesting for you? Mateusz Konieczny (talk) 16:19, 31 May 2021 (UTC)

I've noticed OSM Wiki uses Google reCAPTCHA which I've been almost hit with trying to create my user page. (By "almost" I mean I have Google's domains blocked so my browser cannot download the captcha)

There are automated tools specializing in solving Google's captcha (Buster captcha solver is a freely available example) and I've used some to fully automate jDownloader and similar workflows. Hence reCAPTCHA leaves a lot to be desired in fighting off automated spam.

Moreover, all such tools don't prevent reCAPTCHA's code from running, they simply automate the typing and clicking-through behavior. ReCAPTCHA's code analyzes and attempts to fingerprint your OS and computer. In effect reCAPTCHA de-anonymizes to Google the users of every site which requires its users to solve it. In addition to obvious privacy concerns, as Google is OSM's main competitor, I'd argue doing this to OSM's own contributors is unwise.

I would suggest replacing this with another captcha system, such as Wikipedia's captcha. Rostaman (talk) 03:21, 18 January 2020 (UTC)

See for some context. "I switched to FancyCaptcha for awhile and got shouted at because blind users were unable to complete the captcha.". I am unfamiliar with Wikipedia's captcha (is it usable by us?), but you may try opening a new issue there proposing such change Mateusz Konieczny (talk) 10:12, 18 January 2020 (UTC)
Yeah it seems Wikipedia's captcha has the same problem. I wonder if it could be possible to create some sort of fallback where people can choose to solve Google's captcha if they can't solve the one that doesn't have audio fallback. Rostaman (talk) 02:45, 22 January 2020 (UTC)
It is probably one of cases that are in category of "will be not fixed without someone willing to write necessary code/configuration updates, current contributors are unlikely to have time for that" Mateusz Konieczny (talk) 10:04, 22 January 2020 (UTC)

I wonder if the amount of spam would increase significantly, if we would switch off this CAPTCHA. @Rostaman: Is there any way to get the number of actions denied by reCAPTCHA? --Tigerfell This user is member of the wiki team of OSM (Let's talk) 13:43, 25 January 2020 (UTC)

I don't know, I've never served reCAPTCHA on a website, only solved them. You might want to ask Google or whoever has set up reCAPTCHA on this wiki. I'd say that Wikipedia, despite using a simpler Captcha, doesn't seem to have a large problem with automated spam. They also have nofollow set for links from user pages (see ) - reading that page, this might already by in place here too since this wiki appears to use MediaWiki too. Rostaman (talk) 05:39, 27 January 2020 (UTC)

Yes, please remove the Google Captcha immediately!.--Kartenziegel (talk) 15:23, 6 February 2020 (UTC)

Rendering sample images broken in Taglists if they include spaces or underscores

I've been about to change Template:Map_Features:aerialway and Template:Map_Features:power to taglists, but I see that the rendering samples in the taglists do not work properly. This problem is currently visible in taglists like Template:Map_Features:barrier and Template:Map_Features:military. I'm not sure if the issue is in the wiki software or in taginfo or both, but it appears we can fix this by changing the underscores to dashes instead. Geozeisig, would you be interested in trying to fix this? I know you have done a lot of work to maintain these rendering sample images. --Jeisenbe (talk) 22:37, 26 February 2020 (UTC)

Jeisenbe Can you give an example of how it is meant? I am no longer a friend of taglists because a lot of information is lost.--geozeisig (talk) 06:49, 27 February 2020 (UTC)
Well, I thought that changing the underscores to dashes would fix the problem, but now it does not appear to be working for Template:Map_Features:aerialway. Perhaps the problem is with all png files? See and --Jeisenbe (talk) 08:01, 28 February 2020 (UTC)
Thank you for finding the reason of not displayed pictures in Taginfo/Taglists. I noticed this behavior some time ago also for the historic=* table, see my question there at the discussion page: Talk:Key:historic#Taglist_rendering_pic_not_displayed_e.g._for_historic.3Dcastle_wall. Okay, i could help to fix it, but can't tell when i have time for it. By the way, i also struggle a bit with the newer Taginfo/Taglists system, because for some reason i can't see the preview (edit:"Show preview"-function button). The error message says LOADING TAG LIST... (If you do not see this tag list, you need to enable Javascript). Is there something i have to configure on my machine (Javascricpt seems activated for the used browser - firefox), or is this a general issue? Without working edit:"Show preview"-function i wouldn't want to switch to the taglist system. --MalgiK (talk) 11:03, 27 February 2020 (UTC)
Re: "The error message says LOADING TAG LIST..." - I see this sometimes when I have a bad internet connection, but usually if I hit the "preview" button again, it will show. I agree that it is annoying to rely on Javascript rather than having the table pre-rendered. Perhaps someone can fix this technically.
Interesting, i think i'm trying it when having a good enough internet connection and i can see the delayed situation while loading an "normal" article page Taglist-delay-aerialway-main-page-loading.gif, but it never shows the Taglists after hitting the "preview"-button [5]. --MalgiK (talk) 08:07, 1 March 2020 (UTC)
I do like that the descriptions and images are now the same on Map Features and on the wiki pages for each tag, with this system, and this means that they are more likely to be correct and up-to-date. --Jeisenbe (talk) 04:05, 28 February 2020 (UTC)

Hi, I fixed all problems on the page Map_features : the solution with dash doesn't work properly, the good solution for taglists needs 2 steps. 1. underscores don't work (as it was said above) : you have to put a space instead and only a space. More precisely, if you have an underscore in the name of the file for the osmcarto-rendering parameter in the ValueDescription of the tag, page in English, you have to replace it by a space. Example : for the tag tree_row, the name of the rendering file is File:Rendering-natural_tree_row-mapnik.png. In the osmcarto-rendering, you have to write : osmcarto-rendering=File:Rendering-natural tree row-mapnik.png. 2. You have to wait one day to see the result : taglists work with the taginfo API. Taginfo is updated once a day so you have to wait the next update to see the result in your taglists. Best regards. Fred73000 (talk) 18:38, 20 January 2022 (UTC)

Followup on CAPTCHA

I've recently found out that Cloudflare has its own CAPTCHA service called hCaptcha. It's not tied into Google's surveillance network, it doesn't discriminate against non-Chrome users, it has some kind of token pass system for visually-impaired and/or privacy-positive users, and it's even currently paying webmasters for completed captchas (Google doesn't reimburse its clients for making their users do free work for its AI program). Might not be the best alternative in regards to privacy (since it still relies on a large company) but arguably better than Google. Rostaman (talk) 15:44, 30 May 2020 (UTC)

I'm surprised there isn't a viable open source non-commercial CAPTCHA system out there that could be adopted. When I randomly looked into it a while back it seemed like all the opensource options still sent information to some random server. Maybe there's one I'm not aware of though that could be used by the wiki. As I think any commercial one, Google or not, will probably compromise privacy somehow and therefore be semi-problematic. The only way around it would be to go with an open source one where the information sharing can be turned off or to create one just for OSM. --Adamant1 (talk) 11:52, 5 June 2020 (UTC)
I agree 100%. However the last time I came here with this question the message was that CAPTCHA is necessary and Google's will remain in use because nothing else satisfactory was suggested. That's why I suggest switching to Cloudflare's for the time being until a privacy-friendly software is found, since Cloudflare is a lesser evil than Google. Rostaman (talk) 13:10, 5 June 2020 (UTC)

Google's Captcha is especially vicious because it punishes you for not having a Google account, deleting cookies or using Tor.
If you really want to defeat the SEO spam (NEW: use Cyrillic to fool the admins) you should just demand an OSM account with > 10 map edits as requirement for a Wiki account.--Tito (talk) 20:56, 5 June 2020 (UTC)
I don't think the wiki and main site are connected in way that would allow for the wiki to be able to tell if a user has 10 map edits. As far as I know, they are completely different logins etc. Not that they couldn't be integrated somehow to get around it. But a lot of higher up OSM people that should be able to edit the wiki lack map edits but are extremely active with the organization in other areas. Same for developers. So, arbitrary map edits as a qualifier could be kind of iffy. Although, 10 is a low bar, but it might be low enough for scammers to just map 10 objects then spam away. Which might slow them down but wouldn't stop them. Not that there aren't ways around CAPTCHA systems either though. --Adamant1 (talk) 04:06, 6 June 2020 (UTC)

Discrepancies in wiki articles: can this tag be used on node? way? area? relation?

Hi everyone,

I found some discrepancies between articles. For example, in the article highway=footway, we can see in the infobox (on right) in section Used on these elements, that this tag can be used only on ways and areas. But on the other language pages (ex: FR:Tag:highway=footway), we can see that this tag can only be used on ways and not on areas. And we have the same issue on the highway=* page in the table listing all values for this tag.

And I'm pretty sure there are a lot of issues like this one.

So either we (I) will need to check every articles in every languages (very long task!) or I can create a bot.

So I want my bot to check for those issues and 'print' a report. So a regular user can try to fix those issues. I never created a bot yet, maybe I will use Pywikibot. Does anybody know if this kind of bot work on this wiki? Also, I may want to use Toolforge to run my bot, but I don't know if Toolforge can target this wiki (a wiki outside wikimedia fundation), any ideas?

Have a nide day. --Binnette (talk) 08:54, 9 October 2020 (UTC)

Ok, so it's seems that we can simply remove the parameters "onNode, onWay, onArea and onRelation" to get the 'fallback' values defined here Item:Q5015 in "use on nodes", "use on ways", "use on areas" and "use on relations". (The job is done by the module Module:DescriptionFromDataItem.)
So I'm just gonna edit highway=footway and remove the 4 parameters "onNode, onWay, onArea and onRelation".
Anybody is against my solution? --Binnette (talk) 11:37, 9 October 2020 (UTC)
BTW, we may consider to remove those 4 parameters for all tags wiki articles. So we will may be need a bot... --Binnette (talk) 11:49, 9 October 2020 (UTC)
It’s also worth checking while you’re there whether anything is in the data item is language-specific (images are not so bad but check the rest). --Andrew (talk) 20:55, 9 October 2020 (UTC)
If you delete the VD parameters ("onNode, onWay, onArea and onRelation") you will loose the taginfo displaying compatibility :-( , see on this table: --MalgiK (talk) 21:56, 9 October 2020 (UTC)
Please don't delete the parameters from the actual wiki pages. I also think that a bot is the incorrect way to do this. The right way is to check how each tag is actually being used (by looking at taginfo and overpass-turbo) and make sure the description in the wiki matches how the tag is used by most mappers. --Jeisenbe (talk)
Please don't delete any parameters at all. It is fine to edit them, but I am not OK at all with deleting such content from OSM Wiki pages and relying on this data items (there was a big discussion about this already).

Taginfo placeholders for undocumented tags

I modified the following interface messages in English to embed {{Taginfo}} about the key or tag as a placeholder for prose documentation:

It isn't the prettiest change, but the idea is to reduce reader confusion when encountering a tag that lacks its own page, despite potentially being in wide use, even documented elsewhere on the wiki as part of a broader tagging scheme. Ideally, such tags would have their own pages or at least redirects, but taginfo can serve as a stopgap in the meantime. The taginfo tag statistics box is a mainstay on standard key and tag description pages, so it should be familiar to mappers even without explanatory text.

These three messages are some of the most frequently customized messages among MediaWiki installations. Typically, administrators customize them to more closely tie a wiki to companion websites or make the wiki more user-friendly in general. For example, MediaWiki:Noarticletext would be an ideal place to link to or a Requested articles page, while MediaWiki:Newarticletext could link to suggestions for writing a good tag description page or offer buttons to prefill standard templates. At the same time, I personally prefer somewhat utilitarian "not found" messages, which load quickly and don't take up too much space in the visual editor's flyout panel. Does anyone have suggestions for further customizing these messages?

Unfortunately, these customizations only take effect when your interface language is set to English. I've made similar modifications to the Spanish and Vietnamese translations of this message at e.g. MediaWiki:Noarticletext/es and MediaWiki:Noarticletext/vi and can do the same in other languages if desired.

 – Minh Nguyễn 💬 23:57, 16 October 2020 (UTC)

Unfortunately the taginfo box looks quite strange when the visual editor box is shown, at least in my browser. It is off to the right side but has no white space between the text to it's left, but then there is a large gap below to the left. And the label like "key=value" is not included in the box outline, so it looks like odd text on the page rather than part of the taginfo box.
I think this change will cause more confusion than benefit. If the taginfo box could be updated to show something like "key=value at taginfo" instead of "taginfo [More...]" that would help some, but it will still look odd. --Jeisenbe (talk) 08:04, 17 October 2020 (UTC)
Yeah, floating the box to the right isn’t great in the visual editor. I had originally floated it to minimize vertical jumping in case the box takes a little too long to load. The caption is part of {{Taginfo wrapper}}, which was originally intended for a table of these boxes that could get repetitive. We can make a different wrapper that calls out taginfo explicitly. Another option would be to use the |link = parameter in {{Taginfo}} to display just a link rather than the whole box. Maybe that’s best for MediaWiki:Newarticletext, which has this layout issue in the visual editor. – Minh Nguyễn 💬 16:42, 17 October 2020 (UTC)
I changed MediaWiki:Newarticletext so that the taginfo box no longer floats to the right. – Minh Nguyễn 💬 20:01, 17 October 2020 (UTC)
Another problem: this box is being added to pages like Talk:Tag:railway=yard before they are created, even though this is a talk page, not a tag or key page. Can you fix that? --Jeisenbe (talk) 17:43, 17 October 2020 (UTC)

Redesign of page not found message

As a followup to Talk:Wiki#Taginfo placeholders for undocumented tags, I've started a redesign of MediaWiki:Noarticletext at Template:Noarticletext/sandbox based on w:Template:No article text. Here are the main changes:

  • A modicum of styling distinguishes the message from a very short page, so users familiar with the wiki will immediately recognize the message.
  • The message differs slightly depending on the namespace and also for keys and tags.
  • There are links to both taginfo and a tool to look up the associated data item without having to fiddle with Special:Search's advanced options.
  • For Key: and Tag: titles, clicking "Create this page" preloads some boilerplate with instructions for creating the page. There's a different boilerplate for keys versus values.

This is a work in progress:

  • MediaWiki:Newarticletext should be redesigned at the same time. It might feature a button to optionally load the boilerplate, as in User:Minh Nguyen/preload. It also needs to fit inside the narrower flyout panel in the visual editor.
  • For now, the redesigned message and boilerplates are all in English.
  • When the boilerplate is loaded, we should replace MediaWiki:Noarticletext with instructions for working with the boilerplate. (For example, when the visual editor is enabled, you'd type below each comment, optionally deleting the comment.)

Try it out, entering a variety of page titles to see how the message adjusts to different scenarios.

 – Minh Nguyễn 💬 23:53, 17 October 2020 (UTC)

@Minh Nguyen: - thanks for developing this, how it would be deployed? As filler on text of any page not created after entering it? Filled after deliberately pushing some button? Mateusz Konieczny (talk) 07:30, 21 January 2021 (UTC)
The "try it out" link above previews what a redesigned MediaWiki:Noarticletext would look like. This is the message that shows up when you go to a page like When you click "Create this page", you're taken to a prefilled edit page, which you can fill out and preview before publishing. You can of course continue to edit the page afterwards. Users who know what they're doing can click the "Create" tab at the top of the page to get a blank edit page, or they can simply delete all the boilerplate text and start from scratch. If this is confusing, perhaps the Noarticletext message could offer both options. – Minh Nguyễn 💬 18:33, 21 January 2021 (UTC)
I am unsure about gallery by default. Problem that repeats is that page supposed to describing tag has massive gallery that ads nothing to an article Mateusz Konieczny (talk) 07:30, 21 January 2021 (UTC)
The sections included by default are by no means meant to be required, and sections that aren't needed should be deleted. Perhaps the comments should make that clearer. I was under the impression that galleries are common enough and figured that the <gallery> syntax is fairly obscure. – Minh Nguyễn 💬 18:33, 21 January 2021 (UTC)
What is the plan to make clear that user should save page so that "{{safesubst:#invoke:DescriptionFromDataItem/sandbox|preload|key={{safesubst:#invoke:OsmPageTitleParser|" will generate something? Mateusz Konieczny (talk) 07:30, 21 January 2021 (UTC)
Good question. We can add a message above the edit box (in wikitext mode) and in a flyout panel (in the visual editor) that explains what that gobbledygook does. It would take the place of the existing MediaWiki:Newarticletext message. I'd love to make the infobox code look more like an infobox in the visual editor, but I think safesubst: interferes with that. – Minh Nguyễn 💬 18:33, 21 January 2021 (UTC)
"Where to find them" section seems unusual, not sure whatever have seen it usefully used anywhere and is quite rare anyway. Why it is needed if there is both description of feature and how it is mapped? Mateusz Konieczny (talk) 07:30, 21 January 2021 (UTC)

Sometimes mappers see something in imagery and want to know how to map it, but other times they're browsing the wiki, see something interesting, and wonder if they can map any instances of it in their own area of interest. The definition doesn't always make it obvious where to find the feature, because the location may differ between regions, cultures, or levels of urbanization. Separately, many organized mapping teams have developed their own training materials to supplement the wiki; as far as I can tell, this is a common element of those training materials. In general, I would like the wiki to address the aspects that are currently exclusively covered by those training materials, so that the wiki can be more authoritative and there's less opportunity for conflict between the community and mapping teams.

You're right that this section is relatively uncommon (and sometimes titled differently), but I do think the content that has been placed within this section so far has been pretty useful. I only included "Where to find them" on the tag description boilerplate, because keys on their own don't represent features; some key description pages have an analogous section called "Rationale" or "Use cases". I'm hoping this boilerplate sparks a discussion about the "standard" sections of tag description pages from a reader perspective, but perhaps I'm trying to do too many things at once. :-)

Usage of arearelation icons on boundaries

The use of the icons area and relation are used inconsistently across the wiki when it comes to boundaries (specifically, relations tagged with type=boundary). It is clear that area applies to relations of type=multipolygon. However, a boundaries are more complex - they are a relation of type=boundary with one or more closed ways and optionally nodes with the roles Role admin_centre and Role label. Are boundaries area, arearelation, or relation?

The table below shows the different answers given on different wiki pages.

1. Does area apply to relations of type=boundary?

Yes No

2. Does relation apply to relations of type=boundary?

Yes No

Which icon(s) should be used when describing boundaries on the wiki?

Add Structured Discussions (Flow) Extension

Blacktocat.svg openstreetmap/operations/issues/496

Editing talk pages is hard for new/inexperienced users.

This can be especially frustrating/limiting when wanting to comment on a Proposal being proposed.

Adding the Structured Discussions extension provides a simple interface that allows users to respond, create, resolve, etc. topics easily.

The WikiMedia Talk Pages Project is being worked on but it doesn't look like it's available for install. Converting to this should also be a priority when it becomes available.

—Preceding unsigned comment added by Lectrician1 (talkcontribs) 00:20, 7 January 2021‎ (UTC)

If any of these tools can save us from figuring out the right combination of :::*::*:*:: to preface a comment with, then I'm sold! :-D My only concern with Flow is that it seems to be in maintenance mode as the Wikimedia Foundation has refocused its efforts on more incremental talk page improvements. My impression is that Flow isn't a particularly straightforward extension, since it changes the content model of a page irreversibly and introduces new namespaces. That said, it's a much more polished system than LiquidThreads, which is still annoyingly relying on. So if it does adapt well to a non-Wikimedia wiki, then it would make integral OSM processes like the tag proposal process more accessible to the bulk of the OSM community. – Minh Nguyễn 💬 02:26, 7 January 2021 (UTC)
(1) what would be import plan for old talk pages? Mateusz Konieczny (talk) 10:02, 11 January 2021 (UTC)
(2) is there a working export from StructuredDiscussions to standard talk pages if development on it stops? Mateusz Konieczny (talk) 10:02, 11 January 2021 (UTC)

Following up on my impression above: Flow development was put in maintenance mode in 2015 before it gained enough of a feature set to be adopted more widely. [6] Though the WMF left open the possibility of restarting work on it, the general sense in places like Wikidata Telegram is that the extension is a "technological dead end" and that it won't ever be developed any further beyond basic maintenance. At the moment, that doesn't present a practical issue for us. LiquidThreads has also been in maintenance mode for almost a decade, but uses it today. Still, I would be wary of relying on something in maintenance mode when we could wait a little longer for the new talk page improvements to mature.

@Mateusz Konieczny: Flow is opt-in: there's a special one-time UI command to convert a talk page to be Flow-enabled, and there's no going back (because the topics end up on disparate pages in a different namespace).

I'm unaware of a built-in way to bring everything back to how it used to be if we decide to uninstall Flow. Ultimately, each topic is a wiki page with a unique identifier as the page title, so it should be possible to archive these pages. However, compiling them back into a standard wiki talk page would require a bot to crawl these pages and some assumptions about how the topics fit together. I really do like the Flow interface, but it's a matter of taste and a rabbit hole that we probably shouldn't go down right now.

– Minh Nguyễn 💬 01:25, 27 January 2021 (UTC)

I've used StructuredDiscussions or Flow on the website several times last year, assuming that's what it was. I've found it to work a lot like forums - it has the same set of issues with editing and deleting posts. I wrote a message on someone's talk page and couldn't edit it to fix a typo. Eventually I was told by an admin that nobody can edit my post anymore. I also couldn't delete my own double-post immediately after I made it, an admin had to do it. That was pretty baffling.
I've noticed that Wikipedia now has a "reply" button on talk pages, I think that equally well solves the problem of counting the ::::: and wondering where you need to place your message, without introducing the forum moderation-type problems. Hopefully they'll release it to other wikis soon. Rostaman (talk) 15:36, 28 January 2021 (UTC)
@Rostaman: The "Reply" button is part of the talk pages project that the Wikimedia Foundation is actively pursuing as an alternative to StructuredDiscussions/Flow that's much more flexible. It isn't mature enough to install here yet, but it seems quite promising. – Minh Nguyễn 💬 09:45, 6 February 2021 (UTC)

For future reference, the Reply and New Discussion tools are implemented by mw:Extension:DiscussionTools, which seems like a refreshingly simple extension: backwards-compatible, no special namespaces, and the BetaFeatures dependency is optional. The only downside is that it's currently in beta. If this is a problem, perhaps Commons:User:Jack who built the house/Convenient Discussions would be a good stepping stone, since it's nothing more than a gadget. – Minh Nguyễn 💬 18:47, 8 March 2021 (UTC)

I'm considering installing Commons:User:Jack who built the house/Convenient Discussions as a gadget here, as a stopgap until mw:Extension:DiscussionTools is ready for primetime. Both extensions are backwards-compatible with the wikitext conventions for replies and signatures. The two extensions seem to be capable of coexisting; Convenient Discussions provides some power-user features that DiscussionTools probably won't end up offering, like the ability to move discussions between talk pages. – Minh Nguyễn 💬 06:55, 15 September 2021 (UTC)

This would be extremely helpful to users:

DynamicPageList extension

A recent mailing list post by Lectrician1 got me thinking we should install the DynamicPageList extension. This simple extension adds a tag that allows any page to include a dynamic list of the contents of a category and customize some basic sorting and display options. For example, Proposal process could have a table that looks like this, populated automatically as a result of each proposal page using the {{Proposal Page}} template and sorted by the date the status was last changed:

A similar list based on Category:Key descriptions with status "de facto" could appear on the Changelog. Or these lists could even appear on Main Page to supplement {{News}}, which is very quiet (only three items for all of 2020).

The extension's official documentation includes a warning to only install it on small- to medium-sized wikis due to scalability. Fortunately, I don't think this wiki is anywhere near the scale where that issue would matter. The Vietnamese Wiktionary, one of the largest Wiktionaries about four times the size of this wiki, bravely uses it on its front page to showcase new entries. Also, I think the scalability issue is specific to performing an intersection between two categories (must be in category A and B but not C), which isn't necessary for the use case described above.

If there's agreement that this extension would be useful, we can ask the operations team to install it.

I can't speak for the cumulative effect of many extensions being enabled, but one way of looking at it is that we have far fewer extensions installed than a typical Wikimedia wiki, while the community seems to expect a similar level of service. DynamicPageList is fortunately a relatively simple extension, befitting its relatively minimal benefits, but I think your concern is worth keeping an eye on. – Minh Nguyễn 💬 06:55, 20 January 2021 (UTC)

By way of an update, the MediaWiki developers have reported stability issues due to intersections with very large categories on some wikis.

Add TemplateStyles Extension

I am looking to redoing the Main Page however I require css. This extension allows for separate stylesheets.

Any objections?

--Lectrician1 (talk) 03:52, 6 February 2021 (UTC)

Custom CSS is possible now, it just needs to be installed by an admin. I had to do this for my taginfo box replacement project. No need for a separate extension AFAIK. @Minh Nguyen: --ZeLonewolf (talk) 04:05, 6 February 2021 (UTC)
Yes, Minh and I discussed this. However I run into the issue of not being able to test the css and how it looks on a page before I commit to the actual page. I want to use my user pages to test both the Main Page Wikitext and CSS combination. Not being able to test means going through a admin is practically unreasonable. It's also nice to have publicly-available css stylesheets for easy reference and changes. All Wikimedia projects have this extension and it's been very handy to work with in the past before. --Lectrician1 (talk) 05:03, 6 February 2021 (UTC)
That doesn't make any sense, I had no problem testing my CSS without any special extension. --ZeLonewolf (talk) 05:19, 6 February 2021 (UTC)
Following up from our private conversation, hopefully your browser's built-in developer tools provide the facilities you need to prototype style rules for the main page. TemplateStyles is a nice extension to have, but it is already technically possible to implement something similar without TemplateStyles by writing a user stylesheet that an administrator can turn into a gadget or copy into MediaWiki:Common.css. Gadgets and sitewide stylesheets affect every page for every user, so it's important to scope style rules, for example by prefacing each ruleset with .page-Main_Page .bodyContent. Even then, there is extra overhead loading any page on the wiki, so consider inline style attributes if possible. TemplateStyles is nice to have because you can express more than style attributes but without adding overhead to unrelated pages. – Minh Nguyễn 💬 09:35, 6 February 2021 (UTC)
How can other users see the programmed css for a page after an admin has added it. What if they wanted to redo the main page after me in the future and reference the old css?
In my opinion, using browser tools is going to be much more of hassle for me than just having the easily-installable TemplateStyles.
I also just thought of another conflict I might run into. If I'm using templates on the main page that rely on their own css, will the css I program for the template and main page show up? Templates render based on their source page and if the source page has no css, I'm not sure this will work. The template won't be able to pick up any css references either since it's only coded presence on the main page will be {{Frame}}.
--Lectrician1 (talk) 13:53, 6 February 2021 (UTC)
Okay I tested my "possible problem" and turns out css does work for templates that are transcluded on another page.
However, can we please just add the extension out of convenience?
Evey time I want to change the wikitext, I have to copy and then reinsert the css into into my browser developer panel. There is a lot of Wikitext I'm going to have to change for the main page. This is going to be a big hassle.
Also, as I noted before, it's nice to have the css stored in a file everyone can easily reference, rather than wherever an admin has to store it ingrained in the page. --Lectrician1 (talk) 23:26, 12 February 2021 (UTC)

  • What is the process for linking existing wiki usernames to usernames in a way that's straightforward for users and not a burden on admins?
  • Will the process be seamless for new users?
  • Do we have an issue in the case of name collisions? (in which an user and a wiki user of the same name are actually two different people)?
--ZeLonewolf (talk) 22:18, 8 February 2021 (UTC)
  • It seems that as long as an account on the Wiki and OSM have the same username and/or (not sure) email, then they can login.
  • Yes, it is seamless.
  • I think the emails being the same is the deciding factor.
--Lectrician1 (talk) 22:26, 8 February 2021 (UTC)
It would be great to eliminate this barrier for participation on the wiki, seems very promising! I've got some questions as well:
  • What does it mean that the process is seamless for new users? Can they just log in using their existing account without having to "create a wiki account" first?
Yes. If a Wiki account does not exist with the username and email that is returned by the client, then a new account for the Wiki will be created and the user can continue to use to login. --Lectrician1 (talk) 17:24, 14 February 2021 (UTC)
  • I understand that the plan for dealing with differences between the two sets of accounts is that users resolve these themselves (by changing their user name and/or email address so that they match, or creating an OSM account for wiki accounts that don't have an equivalent yet)? For that to be possible, there will be a co-existence of linked accounts and un-linked accounts at least for a transition period, right?
Correct. It is up to the users to decide when and whether they want to "link" them. They can do so at any time because the login process will remain the same always. --Lectrician1 (talk) 17:24, 14 February 2021 (UTC)
Thanks for attacking this long-standing problem! --Tordanik 14:04, 14 February 2021 (UTC)
PluggableAuth may not be sufficient to address the issue, at it is only a framework to create authentication and authorization extensions on top of it. Also, OAuth2 authentication isn't available yet on the Rails port ( website), which means we cannot use plugins like OpenID Connect. Then, having an explicit link between the Wiki and (vs. an implicit one which relies on the same username across both sites) is the preferred option. Matching via username and email also wouldn't work, because we deliberately don't expose users' email addresses via any API call for privacy reasons. There's quite a bit of work involved here which goes much beyond installing a Wiki plugin. mmd (talk) 11:40, 21 February 2021 (UTC)
@Mmd: What would you suggest be the steps we should take to making this happen then? How exactly could we establish an explicit link? --Lectrician1 (talk) 07:22, 22 February 2021 (UTC)
Well, finding that out would be exactly one of the tasks of the Github issue. We probably need some Mediawiki expert and/or more research to work out possible solutions. Think of the whole topic more in terms of a project, rather than some few hour configuration task. Mmd (talk) 09:36, 22 February 2021 (UTC)
Hm ... the goal discussed in some previous conversations, and when writing that Top Ten Tasks entry, was to eventually get rid of the distinction between OSM wiki account and OSM account as far as practically possible – i.e. users would have the same name, and there would be no need (and no ability) to "create a wiki account". How would the process of establishing an explicit link look for an OSM user editing the wiki for the first time? --Tordanik 19:29, 26 February 2021 (UTC)
@Tordanik: They could sign in with and their account would be created based on the information returned by the OAuth client. This would work exactly the same as when you login/signup with Google on a site and you are able to immedeatly use it. --Lectrician1 (talk) 02:23, 27 February 2021 (UTC)

It seems that further activity would be at - and that is solved as far as we can here, right? Mateusz Konieczny (talk) 10:13, 19 March 2021 (UTC)

Add Page Forms Extension

Page Forms allows users to create forms who's inputted information can then be formatted and inserted into a page.

I would like to use Page Forms to create forms that allow for the easy creation of proposal pages and the management of transitioning proposal stages.

For example, a Page Form could allow:

  • Each of the proposed tags and their used entities, descriptions, and examples to all be easily-inputable and displayed in a standard fashion.
  • Proposal can change stages from draft to proposed to voting to post-vote, all with the configuration of the form. This requires no editing of the proposal itself.
  • Possibly the seamless transition from copying a proposal's data from the proposal to a new page(s) for the approved tags.

Here are examples of sites that use Page Forms.

--Lectrician1 (talk) 00:41, 9 February 2021 (UTC)

"Proposal can change stages from draft to proposed to voting to post-vote, all with the configuration of the form. This requires no editing of the proposal itself." - how it would be detected?
"easily-inputable and displayed in a standard fashion" - how it deals with fact that proposal may propose one new key or new value or values or deprecate existing tag or change voting rules or introduce new key and deprecate specific value (or values) and so on? Mateusz Konieczny (talk) 07:54, 17 February 2021 (UTC)
  • @Lectrician1: - have you tested how this extension interacts with all subsets of extensions that you also proposed? And with current OSM Wiki install? Mateusz Konieczny (talk) 10:44, 23 February 2021 (UTC)
    • @Mateusz Konieczny: I'm going to setup my own install of MediaWiki and test before I suggest we move forward with actually implementing it.
      Also for, "How would it be detected". What I mean is that with Page Forms none of the raw text on the proposal has to be edited. Everything is configured through the form. Selecting an option for a proposal stage in the form should be able to automatically add the voting section to the proposal, etc.
      Form elements are also replicatable so you can setup a field to repeat itself with multiple options. For example, you can add as many tags that you want to propose addding or depreciating etc. IDK if this makes sense :P

Add Translate Extension

Bringing up this archived discussion again.

Translate Extension


  • Direct and up-to date translation will be much easier than the current state.
  • Differences and amount translated of each page in each language is tracked.

How to use

  • Configuring pages to be translated is easy.
  • <translate></translate> tags only need to surround headers, sections of text, and other special formats.
  • The <!--T:1--> tags are auto-generated and do not need to be placed. Only the <translate></translate> tags do.


I am personally willing to take the time to convert as many pages as possible to be translated if this is implemented.

--Lectrician1 (talk) 23:40, 13 February 2021 (UTC)

  • I am against adding this extension. It won't help anything and will only cause more problems. Besides, pages in other languages don't have to be an exact reflection 1:1 of English pages, they just shouldn't contradict. maro21 11:52, 14 February 2021 (UTC)
    • I don't think there are that many good reasons for page in different languages to significantly depart from each other. So in my opinion, it would be very valuable to have software support for translations and to keep track of untranslated/outdated sections. But unfortunately, it seems there has been no progress on the objections from the last time this extension was discussed: The large amount of special markup that would have to be added to the English text. Auto-generation doesn't help much because these tags will still burden every future editor of the English page. This is especially frustrating as it would seem easy enough to just use section headings to split the page for translation – larger restructuring of the page will almost always necessitate an overhaul of translations anyway. --Tordanik 13:19, 14 February 2021 (UTC)
      • No page needs to be "restructured". The <translate></translate> tags are simply added and you're good to go.
        Yes, the auto-generated <!--T:1--> tags can get in the way and might confuse new editors, but editors are warned when they edit a page with a message at the top of the editor that they need to use translate syntax. This message also links to tutorials that I find are very-detailed and easy-to-understand.
        Also, not-using or removing any translate-associated tags doesn't break anything. You just have to make sure every open tag is closed with a closed one (the editor will display an error if there isn't).
        If a new editor makes an addition to a page (such as a new section or paragraph) and forgets to put new translate tags around it, then the Translate extension will simply not show that it needs to be translated or show a longer section in-need-of-translating with the added text rather than the shorter, paragraph-oriented ones. Experienced editors who watch the page will likely fix this so that the translation is present and in the correct syntax.
        --Lectrician1 (talk) 17:41, 14 February 2021 (UTC)
    • It will help everything. There are so many pages that have not been kept up to date and can/should be translated. Pages should be a 1:1 translation. If OSM is a global project, shouldn't we provide the access to all resources in all languages that is up-to-date and consistent so that we don't run into mapping-convention divisions? --Lectrician1 (talk) 17:41, 14 February 2021 (UTC)
  • What is the supposed benefit of this extra code littering page text? Is it compatible with visual editor? Is it mandating that content on each page is the same? Where is its repository and its issue tracker (AKA "is it maintained or abandoned and bitrotting")? Mateusz Konieczny (talk) 07:56, 17 February 2021 (UTC)
    • Mateusz Konieczny: The extra code is used to keep track of the parts to translate. It uses a separate interface for translation that is source-code only for now (see w:phab:T55974). It is maintained and used by the WMF itself on a lot of MediaWiki, meta, and Commons docs, and the bugtracker link is something you can click the links to find out. It does partially mandate commonness, but you can: (a) cheat the system and put something else in, or (b) transclude parts of the translated page in a more flexible article.--Artoria2e5 (talk) 05:54, 20 February 2021 (UTC)
  • I am very much in favor of this thing, as it would represent a pretty big improvement from what we have right now. I do have a bit of an issue with the "marks the page for translation" process, since it often induces delays in updating back on WMF sites. I recommend opening up this position for application by autoconfirmed users so that more people can do the job. --Artoria2e5 (talk) 05:58, 20 February 2021 (UTC)
  • @Lectrician1: - have you tested how this extension interacts with all subsets of extensions that you also proposed? And with current OSM Wiki install? Mateusz Konieczny (talk) 10:44, 23 February 2021 (UTC)
    • @Mateusz Konieczny: Okay so this extension and its implementation is another reason why I need to setup my own instance of MediaWiki. Like Artoria2e5 said, administrators/people with permissions are needed to indicate if a page should be translated. That means if the Translate extension were to be implemented on this Wiki today, we wouldn't really be able to translate any of the pages with out an admin checking through each of the pages and marking them for translation. There are also other things I have to test.
      I am also going to make a tutorial video on how to set up a page for translation the formatting, actually translating etc. so that people on this Wiki knows how it works before implementing it. The tutorial video on MediWiki is too old and long so I think I'll also make the video to replace that one too.
      I don't have a lot of time right now though, so it might be another 1 or 2 weeks before I can get to this.

I would like to reintroduce proposing and implementing this.

@Maro21: Are you still against implementing this, even after the basic instructions I gave on how to use this extension in the videos above?

@Dcapillae: I know that you consitently update EN -> ES translations on Proposal process (thank you!) Would you and others in the Spanish translation community be interested in this extension? It could make translating much easier!

--Lectrician1 (talk) 19:30, 7 July 2021 (UTC)

Yes, I am against. I know how the extension works, because I use it on Translatewiki. It's good to use it for short messages, but not for long articles. Everyone would translate 1/100 of the page and it will be a mess. Do you translate articles to other languages? I do and I prefer to press edit and write the whole article and this extension won't make translating easier, but harder. I also think that article translations into other languages don't have to be 100 percent identical. I often write articles in Polish and sometimes I add more than there is in English. maro21 21:09, 7 July 2021 (UTC)
Hi! Thank you for the video tutorials. I have never used the extension before. Watching the videos, it looks really convenient and easy to use. Maybe it would encourage more users to collaborate with translating. I don't really have a strong opinion on whether it is a good idea to add the extension or not. Many pages on the wiki include templates and tables. If it works properly on those pages too and doesn't give problems, any improvement is welcome. Regarding the Spanish translators community, I think nobody will be against it. We will adapt to any wiki improvements. --Dcapillae (talk) 22:36, 7 July 2021 (UTC)

@Tigerfell: How can we make progress so that this proposal can fully be considered and possibly implemented by the community? Should a formal proposal page be made? Should a discussion be started on the talk mailing list? --Lectrician1 (talk) 01:45, 9 July 2021 (UTC)

I suggest you first contact User icon 2.svgFirefishy (on osm, edits, contrib, heatmap, chngset com.) and ask him whether there was a technical reason for not installing the extension in the past. The chef configuration controls five wiki instances with different extensions. The sysadmins and I once tried to install w:mw:Extension:Maps. It required Composer, which did not work well with the configuration back then. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 15:53, 10 July 2021 (UTC)
(I'll just ask here) @Firefishy: Is this possible to install for this Wiki? --Lectrician1 (talk) 18:58, 10 July 2021 (UTC)

Okay, well User:Firefishy never responded even after emailing them, so I went ahead and created a full proposal page where the entire system and implementation is documented.

The plan is probably to release it to the talk mailing list in 2 days and then maybe 2 weeks later start a vote.

Let me know if I've missed anything and feel free to contribute.

Proposal: Proposed features/Add Translate extension to Wiki

--Lectrician1 (talk) 23:53, 20 July 2021 (UTC)

@Tigerfell: Well IDK when or if Blacktocat.svg openstreetmap/operations/issues/555 will be answered, but at some point, could you make a issue formally proposing the extension? --Lectrician1 (talk) 18:04, 27 July 2021 (UTC)

I would like to have a community consensus or at least a majority decision to back up a formal proposal. When I formally propose the addition of an extension or even write a  Pull request, I essentially decide the case. Nonetheless, the system administrators will check my request, too.
I will review your proposal and comment on its talk page in case I think something should be discussed before voting on the proposal. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 19:50, 29 July 2021 (UTC)

Bug displaying images on Discussion pages in Mobile View ?

When you switch to Mobile view, images are converted to


on normal "Page" wiki pages.
However, when you include images on a "Discussion" page, they are converted to

<span ...> </span>

. This makes them appear as whitespace.

This does not happen in "Desktop" view.

Example: Insert the following template

{{User|Bert Araali|osm=Bert Araali|m=1|noedits=1}}

the transcluded image in the template on a normal "Page" wiki page (switch to Mobile view) will be converted in HTML as:

<img alt="User icon 2.svg" src="" decoding="async" srcset=" 1.5x, 2x" width="18" height="18">

On a "Discussion" page (in Mobile view) will be converted to:

<span class="lazy-image-placeholder" style="width: 18px;height: 18px;" data-src="" data-alt="User icon 2.svg" data-width="18" data-height="18" data-srcset=" 1.5x, 2x"> </span>

As Template:Languages/div and Template:LanguageLink are no longer used since Minh rewrote Template:Languages and the wiki has never had any pages in Marathi the only real concern is what the underlying problem is. Has this been reported on the Mediawiki bug tracker? --Andrew (talk) 15:44, 16 May 2021 (UTC)
I can only speculate that the lack of any Marathi pages on the wiki might have triggered the error. Since I removed this language, the database error no longer occurs. Mmd (talk) 17:00, 16 May 2021 (UTC)
Looks like there is something wrong with the Marathi language in {{Languagename}} template.
See for example
{{Languagename|de}} -> Deutsch
{{Languagename|abc}} -> abc
but {{Languagename|mr}} throws an error
This template uses magic word #language but {{#language:mr}} works well.
{{#language:ar}} -> العربية
{{#language:br}} -> brezhoneg
{{#language:mr}} -> मराठी
I'm still thinking how to solve it. maro21 16:57, 18 May 2021 (UTC)
The {{Languagename}} template was used enthusiastically by, and over-engineered by, a former wiki contributor for purposes such as enabling links to Wikipedias in languages without Mediawiki support. Many (not all) uses can be (and often have been) replaced with #language; {{Languages/div}} needed it for gcf: until the current language template made it redundant. --Andrew (talk) 19:48, 18 May 2021 (UTC)
We could revisit the remaining templates with languagename and convert as many as possible to #language. --Andrew (talk) 05:50, 20 May 2021 (UTC)
I didn't say that we should get rid of the template:). There was a problem only with Marathi language but this language isn't used on this Wiki at all. I think there is a bug with the database somewhere, the template is ok. maro21 19:28, 20 May 2021 (UTC)
Wiki:Babel templates was also affected through Template:Babel list of languages, fixed by replacing Languagename with #language. --Andrew (talk) 11:40, 20 May 2021 (UTC)
I think I’ve found the problem. {{#language:mr}} (Marathi, native name) works correctly. {{Languagename|mr}} expands to {{#language:mr|mr}} (Marathi, in Marathi), which doesn’t. {{#language:en|mr}} (English, in Marathi) also fails. There is no problem with {{#language:mr|en}} (Marathi, in English) so OsmAnd renders. Tagalog has the same problem ({{#language:tl|tl}} fails) and there may be others that we don’t refer to on this wiki. --Andrew (talk) 17:49, 23 May 2021 (UTC)
Good job! But where are these defined? Somewhere in the Mediawiki files? I've never seen source code of Mediawiki and I don't even know where to look for. I checked your examples on English Wikipedia and they work well. maro21 18:07, 23 May 2021 (UTC) --Andrew (talk) 19:02, 23 May 2021 (UTC)

I can't open Key:tracktype nor any other language version: Item:Q784. The bug must be somewhere in the data item because {{KeyDescription|key=tracktype}} itself generates an error. maro21 20:32, 2 January 2022 (UTC)

This is a broader problem than I thought: No tag or key page that has a description in Hebrew can be opened, see:
But it's not this user's fault, because not long ago I was accessing some of these pages and everything was working. Have there been any recent MediaWiki updates? Because sorting by namespace in Recent Changes doesn't work either. maro21 21:01, 2 January 2022 (UTC)

I can open all of those: I don′t see descriptions in Hebrew by default but I get them if I view all languages. I can also view He:Key:fax and fax (Q268). --Andrew (talk) 13:41, 3 January 2022 (UTC)

Category Tree extension missing

Since MediaWiki 1.31, CategoryTree extension is packaged by default, we are running version 1.35, so why is it removed. It is a standard and very nice extension to view categories as dynamic intercative trees and could improve our wiki and navigation a lot. So this is a request to leave it included. and

--Bert Araali (talk) 15:16, 18 May 2021 (UTC)

So is one of the admin's willing to enable it ? Any objections or issues against enabling it ? Bert Araali (talk) 22:12, 19 May 2021 (UTC)
@Bert Araali: Administrators unfortunately don't have access to the configuration files that load extensions. You'll need to ask the sysadmin team to enable CategoryTree. – Minh Nguyễn 💬 10:13, 19 September 2021 (UTC)
@Minh Nguyen: I think Bert Araali intended to ask if one of the wiki administrators supports the request.
I think the extension could be useful when cleaning up categories or just searching for articles via categories (like looking for a similar tool). I just did not yet managed to look at it in more detail. Someone else proposed to add Extension:DynamicPageList (Wikimedia). I wonder if the use cases of both extensions overlap and we should choose either of them. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 21:02, 28 October 2021 (UTC)
@Tigerfell: CategoryTree is different than DynamicPageList, which was proposed earlier this year. The former makes it easier to browse any existing category, while the latter powers special lists based on categories (or category intersections), for example "the latest pages in both A and B but not C". Such a list would be explicitly added to a page in wikitext, similar to how we integrate with OSMCal today. Of the two extensions, CategoryTree would be a no-brainer: it's convenient and, if anything, would reduce load on the servers because users wouldn't have to load full category pages in many cases. – Minh Nguyễn 💬 22:45, 28 October 2021 (UTC)
I requested the extension to be added to this wiki in Blacktocat.svg openstreetmap/chef/pull/463. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 16:06, 7 November 2021 (UTC)

OSM Carto categories

I'm planning to upload some screenshots of OSM Carto and I noticed that we don't have categories for such images. Currently there are:

I think there should be categories with names starting with OSM Carto * because Mapnik is a map rendering toolkit and OSM Carto is a map style. These names are often confused. What do you think? Do you agree?

I think there should be 3 categories:

  • one for icons like this one
  • one for rendering examples used in infoboxes, like this one
  • one for any screenshot from OSM Carto, like this one.

I will create templates, for example {{OSM Carto icon}}, {{OSM Carto example}}, {{OSM Carto screenshot}} which will add a proper license template and categories.

I will create the templates and categories, I just don't know what would be the appropiate names for these categories: Category:OSM Carto icon (or Category:OSM Carto icons?), Category:OSM Carto rendering examples, Category:OSM Carto screenshots? Are these names ok?

I can recategorize files, I'm just asking here for the names of such categories, if they're ok. Category names will only be added by the template, so they can easily be changed anyway. maro21 17:21, 15 June 2021 (UTC)

"because Mapnik is a map rendering toolkit and OSM Carto is a map style. These names are often confused. What do you think? Do you agree" +1, that is a great idea! Mateusz Konieczny (talk) 07:34, 20 June 2021 (UTC)
Template:OSM Carto example has a misleading name - not all OSM Carto examples qualify as Template:PD-shape, only the simplest ones. This name is poorly chosen and should be changed to avoid confusing people. Or just use Template:CC0 here, with Template:PD-shape added to files qualifying for it (@Maro21:) Mateusz Konieczny (talk) 07:34, 20 June 2021 (UTC)
I corrected the description because this template was only meant for simple shapes that qualify for PD-Shape. The purpose of this category and template was to be for simple shapes where there is no data from OpenStreetMap contributors. Can you give an example that does not qualify under PD shape and what license would it have? If there are such instances, this template simply won't be added there. maro21 20:14, 26 June 2021 (UTC)

License of old OSM Carto screenshots

Should old "Mapnik" (a name used for standard tile layer OSM Carto in the past) screenshots like this File:2010 decembris.png, made before September 12, 2012, have CC-BY-SA 2.0 license? I read but I'm not 100% sure. Help is welcomed. maro21 20:23, 28 July 2021 (UTC)

Yes, this change is (1) unable to retroactively remove CC-BY-SA license from old ones (2) not indicating that ODBL was granted to screenshots made in the past Mateusz Konieczny (talk) 07:29, 29 July 2021 (UTC).
Thanks. I asked because I stopped during categorizing the other screenshots. I realized that they should probably have a different license. So I created an additional template similar to {{ODbL OpenStreetMap}} which contains "© OpenStreetMap contributors" + CC-BY-SA-2.0 license: {{CC-BY-SA-2.0 OpenStreetMap}}. Example usage here: File:2010 decembris.png. Is everything ok with it? maro21 18:09, 5 November 2021 (UTC)

Convenient Discussions

I also installed Convenient Discussions as a gadget. You can enable it in the Gadgets tab of the preferences page. This gadget completely overhauls the talk page experience with a more interactive interface that you can edit inline. This is intended to be a stopgap until DiscussionTools is ready to be installed here as an extension (as an alternative to Structured Discussions). However, I don't think it would be prudent to enable it by default, because it's very much the JOSM of wiki talk pages: bewildering to inexperienced users, but difficult for a power user to live without. If you enable this gadget, you don't need Comments in local time, and they probably aren't compatible with one another. Minh Nguyễn 💬 09:53, 19 September 2021 (UTC)

@Lectrician1: That would be mw:Extension:DiscussionTools, which is still in active development. I've been watching these updates closely and I'm eagerly waiting for it to mature a bit before we ask the sysadmins to install it. The problem with installing it now is that they may make breaking changes on the backend at any time, leaving us stranded on an experimental, unsupported version that won't be compatible with future MediaWiki versions. The extension keeps a light touch on the wiki pages themselves but does have a backend aspect to power topic subscriptions and possibly other features down the line. In the meantime, please provide the team with any feedback that you think will make DiscussionTools more useful to an external wiki such as this one. – Minh Nguyễn 💬 23:12, 19 September 2021 (UTC)
@Minh Nguyen I just don't see why we can't install mw:Extension:BetaFeatures. If all of the Wikimedia wikis have it and it's marked as stable, why can't we? I don't get what's going to "break". Beta features are so nice. We don't have to force users to use beta features. Users could opt-in if they want. Lectrician1 (talk) 00:52, 20 September 2021 (UTC)
@Lectrician1: I agree that DiscussionTools is very nice as-is, at least from a user perspective, but that doesn't necessarily mean it's ready for a non-Wikimedia wiki that isn't monitored closely by the WMF ops team. DiscussionTools is currently rated experimental, not stable. Beta would seem like a more prudent time to install the extension. I don't know how far the talk pages project is from beta, but the Usability subproject has barely begun and could yield nontrivial backend changes to support permalinks. You're probably most eagerly awaiting the Reply tool, which has been enabled on all the Wikimedia wikis. (Less mature features like topic subscriptions have only been enabled on a few wikis so far to iron out scalability issues.) But in order for any of the features to become available to users, we'd need to install the BetaFeatures extension. The absence of BetaFeatures on this wiki has already led to VisualEditor hiding some features, so if it isn't too much of a burden on the sysadmin team, we could ask for it to be installed as a first step. – Minh Nguyễn 💬 02:16, 21 September 2021 (UTC)
Okay, ya I understand that it's still experimental. I'd love to have BetaFeatures as requested. It's up to you and probably @Tigerfell whether to ask on operations though since you guys have much more say about the Wiki than I do. Lectrician1 (talk) 13:59, 21 September 2021 (UTC)

Legal requirements to images or media files

> Main topic: Category:Media without a license

Several uploads to the Wiki still have been done without specifying the license and many images are in use missing an adequate license.

On search how to put things better I looked for a guide or at least an annotation, what has to be respected with uploading and using media like images in the Wiki. But I cannot find such!

  • There is one short and unclear note at Wiki_Help. And that page not even is linked at mainpage or main help page Get_help. (Another issue itself.)
  • Even at the Special:Upload page there are several hints but there is no given help what licenses must or can used basically.

IMHO that way we cannot expect "correct" use of media in the Wiki. I myself have my difficulties with seeing what is right now in view of (using) uploads.

I think an upload or media guideline must be created and put at Wiki_guidelines. And the Wiki guidelines must be directly linked at Get_help and at Special:Upload.

Question: Did I miss or overlook a description or guide in terms of licenses with images at the Wiki and can anyone provide a link?

I would really appreciate if more users could help hereby. --Regards, Chris2map (talk) 19:08, 1 November 2021 (UTC)

At Special:Upload you first see MediaWiki:Uploadtext, at least if you see this page in English, German, or Spanish. It mostly focuses on the question whether the uploaded files are relevant to this wiki not so much on licensing. The upload page also features a dropdown menu for selecting the correct license. This is taken from the configuration page MediaWiki:Licenses. Licenses in this list are definitely acceptable. Media license templates lists all licenses I know. I guess the problem with GFDL is that you are not allowed to trace from such files for OSM. I do not know why it should be a problem to upload such files.
Some sort of guideline could be useful.
I currently do not fix the licensing issue because there are still the options to select "None selected" and "I don't know exactly" which leaves it up to others to fix the licensing. This is often more difficult because you have to find out if the uploader took the picture by themselves etc. Just looking at the last ten uploads (until 19:15, 2 November 2021 UTC) you find four without any licensing and one with a contradicting licensing combination. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 23:02, 2 November 2021 (UTC)
By the way, this topic also came up recently in relation to a claim of fair use, which is of questionable applicability to a website based in the United Kingdom or European Union. We should at least do something about Category:Labelled for deletion, but Category:Media without a license needs a lot of work to contact the uploaders for more information (giving them a fixed amount of time to respond before deletion, that sort of thing). – Minh Nguyễn 💬 01:43, 3 November 2021 (UTC)
Deciding whether we can and should keep fair use images is one of things that needs to be done Mateusz Konieczny (talk) 09:55, 3 November 2021 (UTC)
Category:Labelled for deletion can be emptied only be people with admin rights and they do it, though quite slowly (but there is no real backlog here) Mateusz Konieczny (talk) 09:55, 3 November 2021 (UTC)
Category:Media without a license - what you think about splitting it into subcategories "uploader not notified" and "uploader notified", with second split based on notification date? This would make easier to ensure that all editors are notified and later to start deleting images where uploaders were notified and failed to respond for a long time. Right now processing this category is irritating as many images are stuck in limbo, without any action to be taken for now Mateusz Konieczny (talk)
That could work, though it's even more manual work. Wikipedia and Commons actually use a bot to handle these notifications. Smaller Wikipedias don't run bots for them, but most wikis have a template similar to {{Unknown}} that automatically adds the page to a category based on whether it's been tagged for more than a week (or some other time period). That kind of automation requires using the subst: keyword when inserting the template. – Minh Nguyễn 💬 17:56, 3 November 2021 (UTC)
I actually have plans to automate this a bit - but I want to design process before sending thousands of notifications, also it would be nice to have it runnable without relying on bots (even if it would be more tedious). And yes, something subst: based would be included Mateusz Konieczny (talk) 11:50, 4 November 2021 (UTC)
Thanks for your replies! The ideas to straighten or establish a process to handle the license issue sound good. The template to categorize the contacted cases might automatically switch from "uploader notified" to "uploader notified without reaction" after 4 weeks since placing the template (if this works). - The other part, an explanation for normal users what are the requirements, should been made available as quick as possible. Last week I contacted a user who recently uploaded loads of images and he will/might subsequently add source (own pictures) and license information. He didn't complain, but understandably will not be delighted to edit dozens of file pages. - Is there anywhere a kind of document that can provide a basis for the explanation? --Chris2map (talk) 20:41, 4 November 2021 (UTC)
Talk:Wiki#PD-shape_to_series_of_images is related topic where help would be welcome and basically anyone can do this Mateusz Konieczny (talk) 15:31, 27 November 2021 (UTC)

  • Addition to MediaWiki:Uploadtext
Please have a look at MediaWiki_talk:Uploadtext#Addition_of_two_basic_statements. I'm proposing two basic statements for the file upload page. --Chris2map (talk) 16:38, 28 December 2021 (UTC)


I made initial steps toward bot. For example this edit was made by an automated script.

One thing that needs to be done is adding ability to Template:Unknown to pass some text as parameter that would put image into Category:Media without a license marked since 2022-12 (or maybe Category:Media without a license marked since December 2022? With one extra category Category:Media without a license marked since December 2022 or earlier. I would welcome help with doing this part Mateusz Konieczny (talk) 20:03, 28 November 2021 (UTC)

@Mateusz Konieczny: w:Template:Current is an example of a template that optionally takes a |date = parameter; if omitted, a bot will come along and fill it in. w:Template:Copyvio is an example of a template that automatically adds a |date = parameter, but you have to remember to subst: the template. The magical date insertion functionality works because of {{safesubst:<noinclude />CURRENTTIMESTAMP}} inside that template. Hope this helps. – Minh Nguyễn 💬 23:32, 28 November 2021 (UTC)
For now I decided on more verbose {{unknown|subcategory=author notified December 2021}} resulting in Category:Media without a license - author notified December 2021, I think that it is fine. If someone thinks that more magic would be a good idea or that my mediawiki code is poor feel free to change it. Though I think that having minimal amount of magic is preferable and my plan is to anyway apply most of notifications with bot (I will go through an approval process for it) Mateusz Konieczny (talk) 18:34, 2 December 2021 (UTC)

MediaWiki:Uploadtext - Addition of basic statement

(Follow-up of discussion from MediaWiki_talk:Uploadtext#Addition of two basic statements)

-- (copy of last 3 comments) --
I see your points. Let's try a conclusion:
I . Please do not upload any file without clarifying and indicating the source!
II . a) If you are the author of this file, you must make it available under a free license.
b) If you are not the author of the file, the file must be under a free license and you must provide the source.
c) In any other case you have to clarify the legal use and compatibility with OpenStreetMap Wiki. A file without source and license will be deleted later.
(The linked pages would still have to be created.) What do you think? Please check my wording. --Chris2map (talk) 12:41, 29 December 2021 (UTC)
Technically, seems to trend toward allowing at least some unfree images. But maybe it is not necessary to mention it in summary, just link to full version somewhere? But it would be nice to clarify upload text before we handle fair use and have some clear policy on that. Mateusz Konieczny (talk) 13:18, 29 December 2021 (UTC)
I suggest we continue the discussion in the linked thread on Talk:Wiki given the general impact with regards to file uploads. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 13:24, 30 December 2021 (UTC)
-- (end of copy) --

I hope we can get to a simple conclusion without clarifying all parts of licensing and a quick implementation of the statement on file upload page. --Chris2map (talk) 12:59, 31 December 2021 (UTC)

I thought it would be more useful to establish the licensing guideline first and then change MediaWiki:Uploadtext and all of its translations accordingly. Otherwise, we would need to change it multiple times. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 13:08, 31 December 2021 (UTC)
I definitely have to agree with you on the need of a comprehensive guideline and that file upload page should be changed as few as possible. However, the statement "I." of above is matching the common state and appropriate without further guidelining, IMHO. I would like to bring this forward. --Chris2map (talk) 08:57, 2 January 2022 (UTC)

Guidelining chart for media file licensing

I want to put my draft for a chart up for discussion: Drafts/Media file license chart --Chris2map (talk) 10:36, 2 January 2022 (UTC)

Thank you for that! Maybe asking LWG for review could be useful? Mateusz Konieczny (talk) 08:03, 6 January 2022 (UTC)
Yes, at least we could ask. Per which way? legal-talk mailing list? - Should we go soon or first turn another round in wiki and try to get more feedback from team or contributors? This was my intention. --Chris2map (talk) 12:31, 6 January 2022 (UTC)
It would be nice to get more feedback before taking any further steps of survey and proposing. I don't want to rush ;) --Chris2map (talk) 15:02, 6 January 2022 (UTC)

Beside the chart to help what to do with uploading regarding licensing, we need to help how to do it (technical/practical), don't we? E.g. where and how to edit, how to embed license, layout things (like header), etc. I think that should be provided on another page (a manual / step-by-step instruction) and not on the chart's page. What do you think? --Chris2map (talk) 17:12, 15 January 2022 (UTC)

Designing policy for handling files without clear license

OSM Wiki has a serious problem with files that have no clear copyright status.

We have many files that are blatant copyright violations.

Many wiki pages is using clear known copyright violations or files with unknown status.

There are following groups

  1. Clear copyright violations - obvious copyright violation, also files where uploader admitted that files are copied from random website, Google Street View or source is stated. Or files copied from Wikimedia Commons that were deleted there.
    • Such files should be identified and marked with {{Delete}} template
  2. Files openly licensed and marked as such with proper licensing template, with clear source
    • Not a problem
  3. Files where licensing info is stated, but in text rather than using a proper licensing template
    • In such case licensing template should be applied
  4. Files where licensing info is missing and author was never notified about problem
  5. Files that were clearly uploaded in good faith by OSM mappers, but without any licensing info and uploader is inactive
    1. What should be done with such files? Delete? Keep and mark specially?
  6. Fair use - unfree images that re impossible to replace and important

Why this cleanup is worth doing?

  • Copyright violations are illegal and in general unethical
  • Files with unknown copyright status have limited usability and are a legal risk
  • Reputation of ignoring copyright is unwanted for us
  • OSM Wiki content, including images, should be safe to use and usable by others - not filled with traps
  • Nearly all problematic images are replaceable by superior images


  1. How long we should wait between notifying uploader and deleting the image? 2 months? 4 months? 1 month?
  2. Is it desirable to delete old irreplaceable images with unclear licensing status uploaded by OSM mappers? For example photos of OSM events?
    1. If such images would be kept - how to specify rules to block further uploads without a clear status?
  3. Is it OK and desirable to have some fair use images? On which rules?
  4. Have I missed some category of images?
  5. Is it OK to upload "noncommercial use only images"? This is problematic as it is not really clear which use is forbidden, severely restricts reusability and so on. Wikimedia Commons is not allowing such images for quite good reasons
  6. Would it be OK to allow user-page only personal images that are not openly licensed? See User_talk:Nacktiv
  7. Template:Maxar image - Are we allowed to use Maxar imagery such as for illustration on wiki? If yes - why and how? (it is not covered by editing permission - "you understand and agree that you may only use our imagery to trace, and validate edits that must be contributed back to OSM. You cannot download our imagery or use our imagery for any other purpose" - Maxar
  8. Template:Bing image - Are we allowed to use Bing imagery for illustration on wiki? If yes - why and how? (it is not covered by editing permission - "The rights that you have under this agreement are limited solely to aerial imagery use in a non-commercial online editor application of OpenStreetMap maps (an "Application")." - Bing Maps)

Please, if you have any opinions on questions raised here - please comment. Mateusz Konieczny (talk) 02:36, 9 December 2021 (UTC)

Example where it is not entirely clear who is the author: - this file is from Commons:
Re questions:
1 - I would say 6 months. But we can also try to contact them on because it's more likely they will read the message there if they haven't been logging in to the Wiki for a long time. But 6 months for old files, uploaded long time ago and where the user is not active.
2 - I wouldn't delete them.
3 - Yes, if there is a need, as in the examples you gave. maro21 22:57, 9 December 2021 (UTC)

@Maro21: "6 months" That is for old images, right? What about brand new upload where user was notified within days from upload? Would it be OK to have shorter time there? Mateusz Konieczny (talk) 08:14, 10 December 2021 (UTC)
I assume that in such cases they will react, answer and add a license sooner than later ;p. Otherwise yes, shorter time would be ok, 1 month? maro21 16:45, 11 December 2021 (UTC)
IMHO 3 months for old ones is OK, but I'm also fine with 6 months. For new ones, if uploader is notified in same week (within 1 week) then 1 week time limit from moment of notifying should be adequate. If within 2 weeks then +2 weeks. Within 1 month then 1 month. - What about this proposal: If image file is uploaded without selecting a license, there will be automatically added a template that indicates there is no license and sets a time limit (e.g. 2 weeks) for deleting the file? --Chris2map (talk) 19:16, 11 December 2021 (UTC)
@Maro21: "I assume that in such cases they will react, answer and add a license sooner than later" - at least some are no longer active, sometimes for 10 years and more. We have large enough project that some left completely (sometimes due to lack of further interest, some were banned and some died) Mateusz Konieczny (talk) 08:08, 12 December 2021 (UTC)
I meant recent uploads from active users, that they will react sooner so 6 months period won't be necessary. maro21 21:56, 12 December 2021 (UTC)
3 - Are screenshots of websites such fair use images as long as they are used as previews in descriptions or lists of the website service and the service relates to OSM in some way? (e.g. List of OSM-based services) --Chris2map (talk) 19:02, 28 December 2021 (UTC)

7 - (Use of images of Maxar imagery) In most cases images are used in the wiki to describe or support the tracing or validation process. Might this be interpreted as part of validation? --Chris2map (talk) 13:50, 28 December 2021 (UTC)

Good point, maybe it would work with broad interpretation Mateusz Konieczny (talk) 14:14, 28 December 2021 (UTC)

2.1 - (how to specify rules to block further uploads without a clear status) Wikimedia Commons uses abuse filters (like #31, #154, #156). There is also an abuse filter preventing the upload of files without a license. This solution avoids that administrators have to review the obvious cases of copyright violations. Otherwise, I expect a lot more deletion requests coming up. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 13:29, 31 December 2021 (UTC)

Other group of files - here is another group of files. This group of files is group of downscaled images from Wikimedia Commons and other wikis.

Where file is on Wiimedia Commons (typically under the same name, just without 800px- at start) - replace uses by full image and mark downscaled for deletion

Where file was deleted on Wikimedia Commons as a copyright violation - - remove uses and mark for deletion

If source is unknown - ask uploader Mateusz Konieczny (talk) 17:52, 12 December 2021 (UTC)

More here: maro21 21:58, 12 December 2021 (UTC)
Just applying {{Superseded by Commons}} where applicable may be good enough, maybe I will make some file replace bot to automate the drudgery... 09:07, 13 December 2021 (UTC)

Hi! How do we categorize and handle images such as user certificates like [7]? I think they are a mix of no. 4, 5 and 6 of grouping listed above. And under which license the uploader / author could publish them? - Should or could we have a simple copyrighted content for use by user on user page only license (template)? --Chris2map (talk) 23:12, 27 December 2021 (UTC)

Oh dear, for example is a derivative work of at least NAKHA logo (likely) and three photos, each requiring documenting license. Not entirely sure whether we can and want to allow unfree copyrighted content on user pages. And this one is on Naksha 2021 which is not an user page anyway. Note that example certificate with unfree photo of human would likely not qualify for fair use as it can be replaced with a freely licensed photo. Mateusz Konieczny (talk) 10:34, 28 December 2021 (UTC)
Whew! How do we proceed? Does it require discussion in forum and/or mailing list (though IMHO the stage is here)? I wouldn't resist if we excluded such images without exceptions to user pages. That would make things easier. - While I'm pondering if there could be a way to have exceptions for user pages. But the image files should be clearly and reliably marked for that exceptional use case. E.g. the image should wear an imprint or watermark and the file name should contain a default part (like "user-only-(c)-image_..."), even better would be a new namespace (like "User_file:" instead of "File:"). But I can't see how we could implement or ensure such a marking. --Chris2map (talk) 14:27, 28 December 2021 (UTC)
There are two parts (1) can we legally hosts such files (2) do we want to allow hosting such files. I am unsure about both (1) and (2). Main problem is that allowing unfree images can end with many illustrations having various strict restrictions while big part of Wiki is to make this content freely usable. Maybe for now have some separate template? {{Unknown}} and {{Unknown license for OSM content impossible to replace}}? With note that status of such material on OSM Wiki is not clear and is not resolved? Mateusz Konieczny (talk) 14:51, 28 December 2021 (UTC)
"Does it require discussion in forum and/or mailing list (though IMHO the stage is here)?" - I think that discussion limited to this page is sufficient as it is OSM Wiki specific (unlike tagging), though if someone wants they can notify others that this discussion exists Mateusz Konieczny (talk) 14:53, 28 December 2021 (UTC)

copyright violations that needs replacement

I would really appreciate help with removing copyright violations. Files were not reviewed for a long time and there is a noticable backlog. We really should not use images illegally - it is problematic for several reasons. (resurrecting as I keep finding such file at rate greater than I can process) Mateusz Konieczny (talk) 18:06, 12 December 2021 (UTC)

Generally editable part

Help is needed with handling some illustrations that turned out to be a copyright violations.

You can help by following:

  • open file page of one of files below
  • Go to "File usage" section and open page or pages listed there
  • Replace it with some alternative (preferable) or remove it
    • Note that proposed alternative images are listed at given file pages
  • Save page with edit like "remove copyright violation"

Once file is not used anymore

  • replace {{Delete proposal}} by {{Delete|Unused copyright violation, see file talk page for details}} to let wiki sysops that file should be deleted
  • mark such file as processed by removing it from the list below


For files without replacement:

  • Find acceptable (or better!) image on Wikimedia Commons
    • Or upload file on a free license to Wikimedia Commons / OSM Wiki
    • You can take image on your own and release it under open license
  • Edit file page with note where such image is
    • Or immediately do steps listed above
  • Edit list below and remove this file

Proposed bot edit on Wiki - Wikimedia Commons duplicates

I want to automatically mark files as Wikimedia Commons duplicates for processing.

Getting rid of files duplicating Wikimedia Commons files is useful as there is no good reason for keeping local duplicates of Wikimedia Commons images. This leads to a pointless duplication of effort and both Commons and OSM Wiki has huge backlogs in processing images.

For example reviewing files for copyright violations, improving descriptions, adding categories needs to be done twice what is pointless waste of effort.

In addition many duplicates on OMS Wiki have poorly stated licenses - many files downloaded from Wikimedia Commons and uploaded here have simply wrong licenses (CC-BY-SA 2.0 file uploaded here as Public domain), there are files requiring attribution and not stating author and so on. While Wikimedia Commons file has a proper metadata.

So I propose edit with following part:

@Reneman: @Lyx: @Tigerfell: - if that would be easier for you and would be processed - I can also generate list of files for deletion rather than filling Category:Labelled for deletion

Edit would be automated, made using separate bot account. I would review edits but not all of them. I have experience with bot edits (Mechanical Edits/Mateusz Konieczny - bot account - for now edits in mapping database). In case of causing damage caused by bugs in a bot I would do all work necessary to repair it.

Please comment of you either support such edit or oppose it. I can continue doing it with reviewing every single edit but it seems waste of time for me. Mateusz Konieczny (talk) 10:51, 29 December 2021 (UTC)

How many files are approximately effected? 100? 1000? Regarding File:2014 Meilenstein in der Dresdner Heide.jpg, there is the situation that a user apparently copied a file from OSM wiki to Commons. They stated OSM as the source. AFAIK this is okay, but we need a license review in Commons before the file can be deleted here. Such cases should probably be handeled separately. Reneman once organised such a transfer. Maybe he can explain it better... --Tigerfell This user is member of the wiki team of OSM (Let's talk) 21:09, 29 December 2021 (UTC)
I would expect around 400, but may be less may be more Mateusz Konieczny (talk) 07:07, 30 December 2021 (UTC)
I can add an additional check and ignore ones where upload to Commons was later than upload to OSM Wiki and review such cases manually. BTW, I looked at and it seems fine Mateusz Konieczny (talk) 07:09, 30 December 2021 (UTC)
That sounds good. The upload in question is okay. It is just that the user at Commons can not prove that the upload was legitimate after the file was deleted here. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 13:58, 31 December 2021 (UTC)

if that would be easier for you and would be processed - I can also generate list of files for deletion rather than filling Category:Labelled for deletion

in my optinion, it depends. In the first case, they could be marked for deletion. I think the second case is tricky because one also has to take into account files referenced on the mailing lists, the forum, and the user diaries. @Chris2map: This is the reason why I am hesitant to delete "unused files" and "unused redirects" in the file namespace that do not have any other issues.
The third case is pretty straight forward, I would just delete the files without {{Delete}}. The current version of MediaWiki:Uploadtext states that "Duplicates of files present in Wikimedia Commons" "should not be uploaded to OpenStreetMap wiki" and even continues with "the file in the OSM wiki will be deleted, because it can be used directly from Commons". For organising, it would be the easiest to have a list of such files and then I would delete all the files on that list. --Tigerfell This user is member of the wiki team of OSM (Let's talk) 13:53, 31 December 2021 (UTC)
How are you going to find such files? maro21 21:18, 1 January 2022 (UTC)
There is an API call listing files and their Wikimedia Commons duplicates, if any. I can link code used for that. The API is quite irritating (there is no way to list files only with exact duplicates, so it is necessary to check all files), but it is possible to automate and eliminate drudgery Mateusz Konieczny (talk) 03:00, 2 January 2022 (UTC)
How are cases like File:Balkanabat-Turkmenistan-explorers-statue.JPG which is a hash-perfect duplicate of commons:File:Discoverers-statue-by-Juma-Jumadurdy-Balkanabat-Turkmenistan.jpg handled? This file has been uploaded by the same user as on Commons but using a more liberal license than there. --Nw520 (talk) 14:41, 5 January 2022 (UTC)
Good question. For now I marked Wikimedia Commons file as available also more liberal license Mateusz Konieczny (talk) 16:54, 5 January 2022 (UTC)

Proposed bot edit on wiki - request specifying source and license, mark files

There are thousands of files in either Category:Media without a license - without subcategory or without any category at all There are also other files without licenses not caught here.

I propose to run a bot edit that would

Edit would be applied to all files without proper license template or without stated source.

For practical reasons the edit would be limited and skip, at least initially, some files.

I would review each batch before edit to not bother uploaders about cases where all information to handle licensing is stated already (but I will not catch everything!) - and to handle separately cases where default message is not fitting. Review would be using something like

It would be useful as it would notify uploaders about problems with their files and hopefully will result in filling missing licensing data and/or releasing images under free licenses.

In the worst case we would replace problematic images with ones available under free licenses - also an improvement.

Note that this edit will affect about 22 000 existing files and many that will be uploaded in future without properly stating license and source. Right now it is 22 034 files + files that have categories but neither {{Unknown}} nor any license template or are without info about source ([8][9])

Edit would be automated, made using my regular user account. I would review edits before making them (with that image overwiev). I have experience with bot edits (Mechanical Edits/Mateusz Konieczny - bot account - for now edits in mapping database). In case of causing damage caused by bugs in a bot I would do all work necessary to repair it.

Note that message to user will propose to post to Talk:Wiki (this page) in case of unclear copyright situation and message will be send to many users - so it is expected that many will post here asking for help (I am planning to answer them, but help from others would be appreciated).

Please comment of you either support such edit or oppose it.

Please, comment if you have ideas how this message to users can be improved. For example I have seen some promising project to create guide how to select a proper license - linking it once ready would be really useful.

Basically I support this! Small hint: In Category:Media without a license - without subcategory there are files, already marked with {{Delete}} or {{Delete proposal}}, and therefore might not have to be processed additionally. --Chris2map (talk) 12:52, 29 December 2021 (UTC)
For {{Delete proposal}} I would likely still process them - if file is not mentioned on talk page of the user then notification to make them aware of it would be likely useful (surprise deletion is not the goal). {{Delete}} likely not as this is either clear case or will be changed to {{Delete proposal}}. And for example {{Superseded by Commons}} files also would be skipped, files with {{Trademarked}} would be also skipped until we have clear decision how to handle copyrighted unfree logos.

See and for manually made edits showing how such edits would look like (talk page edit had copy-paste problem with overly represented nowiki, sorry for that - it would not appear in bot edits) Mateusz Konieczny (talk) 18:34, 29 December 2021 (UTC)

I partially oppose it. Adding {unknown} to all UncategorizedFiles is bad. This will not improve anything, it will only make manual verification more difficult. Writing to the authors ok... just consider that most of the images were uploaded more than ten years ago, and their authors have already retired from OSM Wiki...

For some of the images from Special:UncategorizedFiles one can add the license without writing to their authors:

  • some of them have the license given in the description, but there is no template
  • OSM-based maps have a known license
  • screenshots from JOSM and other OSM applications too
  • simple shapes can have {PD shape}
  • copies from Commons which can be unlinked and deleted
  • etc.

Your edit would only "move" files from Special:UncategorizedFiles and won't change anything, and would only make things worse.

This above referred to Special:UncategorizedFiles, but I don't mind doing it for Category:Media without a license.

There is another solution to this problem. We can [can we?] find the users who have uploaded the most files. See if there are unlicensed files and write to these people. There is also a user who uploaded more than 1,500 files but we know now, that they can be marked as one a of a free license: public domain or similar, so you can start from them - it will decrease the number of UncategorizedFiles and files without a license.

And you can start from files that ARE categorized but don't have any license template or info and they are not Uncategorized. Such files are not easy to find, or better to say, almost impossible to find manually.

Moreover, I am also planning/preparing a guide how to choose a license for existing files. It won't be finished very soon, but in the future it might help people or authors of the uploaded files to choose the license. maro21 21:17, 1 January 2022 (UTC)

Note that it would not be fully automated edit. On spotting cases where sufficient information would be already provided I would do proper edits myself. I already found and restated several hundred simple logos while testing my code.

Edit world go like this: generate batch for testing like In case of any images where I can fix problem I would fix them and generate a new batch.

Only in case where all images require help from uploaders I would apply templates and notify uploaders.

Wikimedia Commons duplicates would be handled by mass edit mentioned above and skipped.

For JOSM screenshots, OSM Carto screenshots, iD screenshots I would also simply apply proper templates if possible rather than pinging uploaders.

Marek kleciak images are already skipped and I will generate list for handling them rather than spamming talk page.

Is it resolving your concerns about pointless talk page edits? Mateusz Konieczny (talk) 02:53, 2 January 2022 (UTC)

"Your edit would only "move" files from Special:UncategorizedFiles and won't change anything, and would only make things worse"

Main difference is that authors would be finally notified without plenty of manual drudgery. While doing it manually is not worth it, but automatic applying requests is simple enough to be worth even some responses.

Also, in what case this edits would make situation worse? Mateusz Konieczny (talk) 02:53, 2 January 2022 (UTC)

"it will only make manual verification more difficult" - it will be done as part of manual verification, I want to automate solely step of making requests to uploaders and marking images as ones where uploader was notified about problem - after quick manual review confirmed that current image fails to explain source or license Mateusz Konieczny (talk) 02:53, 2 January 2022 (UTC)

User:Mateusz_Konieczny/notify_uploaders has edit log in case of actual use Mateusz Konieczny (talk) 17:29, 6 January 2022 (UTC)

I admit that tests have higher response rate than I expected, see for example:

Mateusz Konieczny (talk) 14:39, 7 January 2022 (UTC)

I am starting edits, initial ones will be fully reviewed - when I confirm that everything works well I will start ones where notification runs are not reviewed (but targets will continue to be reviewed). Such not reviewed notification runs (with manually reviewed targets) will not start earlier than 14 days after submitting this proposal. Mateusz Konieczny (talk) 11:20, 9 January 2022 (UTC)

Resolved: I will be making edits (all with review for now as I have some not fully tested parts of code), but at some point notification itself will be more automatic. Still - after manual review Mateusz Konieczny (talk) 10:37, 13 January 2022 (UTC)

BTW, on (especially on the bottom) there are many {{PD-shape}} images - marking them would be a welcome help Mateusz Konieczny (talk) 10:37, 13 January 2022 (UTC)

Though note that photo such as File:Wegzeichen Alte2.jpg do not qualify for PD-shape. It is about things like File:White 2 in white circle with Ns above.svg Mateusz Konieczny (talk) 10:38, 13 January 2022 (UTC)

Migrate taginfo to AJAX-based rewrite

Please comment on this proposal to replace {{Taginfo}}'s implementation with {{Taginfo2}}. A migration was previously discussed but the discussion was inconclusive. – Minh Nguyễn 💬 21:24, 2 January 2022 (UTC)

We need a screenshot of a parking lot

Does anyone have a well mapped and nice looking surface parking lot in their area and could take a screenshot? We need to replace this file File:Mapping-Features-Parking-Lot.png - this is how a parking lot and roads looked like in 2009, currently there is no yellow backgroudnd color. And this file is used on a very large number of pages, including e.g. amenity=*, So instead of unlinking it manually, we should override it and upload a new version. Thanks in advance! maro21 16:14, 6 January 2022 (UTC)

Allow users to change their username

I changed my Openstreetmap username last year. After that I tried to change it in the Wiki as well. Unfortunately there is no way to do this at the moment. Is it possible to implement this feature or add instructions on what to do? --Eifelkobold! (talk) 23:11, 8 January 2022 (UTC)

The bureaucrats can do that for you. --Andrew (talk) 22:18, 8 January 2022 (UTC)
Resolved: advice given, I created Change username and some related pages Mateusz Konieczny (talk) 10:32, 13 January 2022 (UTC)

Templates for licenses requiring credit should check for it

There are some licenses that require attribution.

But it is sometimes missing, see for example

In some cases uploader is author, but in some not. And it is not always certain.

I propose to replace free floating credits like

{{cc-by-2.0}} author: Foobar

by automatically checked


That would make possible to automatically detect cases where attribution is missing

Alternatively, create a separate template for author:


It is better because such new template would be easier to use (non need to modify many templates), but detection of missing authorship would not be possible using categories on Wiki, but a script crawling through pages

Mateusz Konieczny (talk) 15:54, 15 January 2022 (UTC)

Hi Mateusz! Why do one have to modify templates in case of the script thing? Couldn't you script to provide e.g. {{cc-by-2.0|Foobar (Author)}} instead? --greetings, Chris2map (talk) 16:36, 15 January 2022 (UTC)

Script would be needed in case of going with {{cc-by-2.0}}{{author|Foobar}}. In case of going with demanding {{cc-by-2.0|author=Foobar}} (or {{cc-by-2.0|1=Foobar}}) no script would be needed. In either case part of the work would be on converting free floating author into something machine readable and asking uploaders to fix remaining ones Mateusz Konieczny (talk) 22:02, 15 January 2022 (UTC)
OK, I just wanted to point out that templates with cc-by already have parameter 1 for attribution. The inline variant is ok for me, also if work may be to do on license templates. - On the other hand we might yet fundamentally need an extra template to structure the process of licensing by uploaders (I have started a first draft User:Chris2map/Sandbox#Testing_Template:License_of_file). --Chris2map (talk) 10:00, 16 January 2022 (UTC)
