Site Status

What is the status of this project? And why has the website been down? Cheers! –Todrobbins (talk) 14:28, 16 January 2014 (UTC)

The machine that was hosting OHM died and finding a new home has been trying. Should be up shortly. --Muninn project (talk) 13:29, 13 February 2014 (UTC)

For the latest information, see the OHM mailing list https://lists.openstreetmap.org/pipermail/historic/ Currently still down. --SomeoneElse (talk) 12:41, 13 October 2016 (UTC)

Time/history/life cycle concepts

Was there any discussion regarding this? There is a pretty decent Comparison of life cycle concepts. The use of start_date and end_date that was suggested in the transcript ( http://www.slideshare.net/frankieroberto/mapp-history-on-open-street-map ) seems to be the worst choice for a rich historic map. RicoZ (talk) 12:38, 19 December 2014 (UTC)

After some thinking I think that in most case the date namespace suffix is the way to go for most historic features. It is already routinely used with name=*, fully compatible with all existing tags and does not break backward compatibility of anything. A slight disadvantage is moderate data duplication and not easy to search for keys marked this way (a regexp is needed). RicoZ (talk) 11:52, 20 December 2014 (UTC)

RicoZ - are you still looking at / interested in this topic? We're currently doing some dev work and could possibly switch conventions, but are currently still recommending basic start_date=* and end_date=* based tagging. It is cumbersome for some applications (e.g. changing names), but we'd need to do more active dev to help support rendering tools. --Jeffmeyer (talk) 20:27, 6 June 2019 (UTC)
Yes, still interested in the topic although in the next time I can not help with programming. Recently there were several discussions in mailing lists, one of them about "start_date variants" showed another interesting idea - using eg "building:start_date=". So you might keep start_date/end_date and use it either as main key if it applies to all properties of an element or namespaced if different dates apply to different properties/attributes of an element. The date namespace still has the more obvious solution if a property was valid during several distinct periods of times. RicoZ (talk) 19:47, 8 June 2019 (UTC)

Update issues

Going to try and fix some bad links in section 4 that have suspicious extra characters at the end that are causing problems.

I've been trying to find links to OHM pages of documentation and support details after one account locked up for no clear reason and kept being sent via the links to OSM and OHM (update on migration failures). The link given when I was locked out was only for the OSM support and so they naturally couldn't help with a OHM based problem. If volunteers needed to fix port link fails or at least compile a list of them for others to work though let me know. {OHM - HGovanus/fgovanus} --Govanus (talk) 18:13, 7 October 2015 (UTC)

Will this ever come back online? Is this a lost cause? Does anyone have a status report or a reboot timetable?

Govanus - it should be up now. --Jeffmeyer (talk) 20:28, 6 June 2019 (UTC)

Old railways..

Way back in the mists of time, on a test server I traced out a good proportion of the Borders, Southern Scotland and Southern England, from a combination of background layers.

This project was later abandoned.

I propose to start adding these to OpenHistorical map if there is interest, as the interface is near identical to that I would have been using on the test server.

However, it wasn't clear if there was ever an agreed convention for making disused vs obliterated stations. ShakespeareFan00 (talk) 17:01, 24 May 2017 (UTC)

I've added the Helston Branch in Cornwall, which if you adding much much older stuff I can remove. ShakespeareFan00 (talk) 22:43, 24 May 2017 (UTC)
ShakespeareFan00 - yes, we'd love to have you add this information, if you still have it available. --Jeffmeyer (talk) 20:27, 6 June 2019 (UTC)

Usage with Marble ?

Would be great to implement this in Marble and to be able to scroll through the wikipedia:Migration_Period or similar historical events. Are values planned which could enable this ? user:rtfm Rtfm (talk) 20:26, 4 May 2018 (UTC)

Rtfm - Totally agree. I think we need to get some ambiguous border type of features and possibly some tool for overlays to treat the Migration Period well, but that's definitely what we have in mind. --Jeffmeyer (talk) 20:27, 6 June 2019 (UTC)

No access to the OHM-server with JOSM

Hi, with JOSM 13367, I get no access to the OHM-Server. I'm not able to make an access identifier. I tried to make a new one and logged in with my OHM user data (username and password), but it doesn't work. Can anyone help me? What am I doing wrong?

I had the same problem. I only managed to make it work through remote control from the website. Try that. 7rst1 (talk) 21:33, 4 March 2019 (UTC)
Hi 7rst1, oh interesting, thank you. I'll try it as soon as the queue at ohm.org isn't full anymore ;) Lukas458 (talk) 20:53, 8 March 2019 (UTC)
Unfortunately, that also did not work for me :/ Hmm, I think I'll have to edit further with iD... Lukas458 (talk) 18:44, 9 March 2019 (UTC)
Lukas458 - are you able to get up and running yet? I've been using it. Do you have an account on OHM & an account set up? --Jeffmeyer (talk) 20:27, 6 June 2019 (UTC)
Hi Jeffmeyer, thank's for your response, it works very well at the moment. I just forgot to post it here, the thing which caused my problem was, that I tried to use the "OAuth" software or whatever that is to log me in with JOSM accessing the OHM-server, but that was what didn't work. Now I use the "classic" basic legitimation with JOSM accessing the OHM-server, and everything works fine. Sorry I did not notice to write that here. There still are occasionally moments when the server seems not to be accessible, but then it seems to be not accessible at all, so also on the OHM-website not, but that has nothing to do with my originally problem. And it only appears some rarely times, so everything is ok ;) --Lukas458 (talk) 20:03, 15 June 2019 (UTC)

Tagging subpage

I have added the missing page on Tags and provided for some verying categories based on status; discussion on whether i've gone the right way is welcome. I think the proposed tags on this page should move there, and I have some thoughts on them going forward, which I'll add later. Nfgusedautoparts (talk) 18:33, 13 January 2020 (UTC)
