Q. There are various situations where a feature has different names in different languages. In some regions, places and streets have names in all local languages. People will also want to render maps in a specific (not necessary local) language. See also Talk:Key:name.

A. People seem to generally agree on using name:code where code is a language's ISO 639-1 code, or ISO 639-2 if an ISO 639-1 code doesn't exist.


  • what should the plain name tag be (local name, at least if not disputed), and how to specify the language that the name tag is in.
  • how to specify transliterations. It has been proposed to use a key of name:code_trans where code is as above and trans specifies the transliteration. There doesn't appear to be a standard list of transliteration codes.
Street signs in Lebanon are written in Arabic and in French, tagging is name=بيروت for arabic name name:fr=Beyrouth for the french version, for the english version name:en=Beirut.

Q. I spoke to an IT guy in the fuel distribution. i may have access to all their GPS locations (united gaz stations) . Can we upload categorized POIs to osm? the osm website upload tool accepts only tracks, right?

A. You can upload anything that is :

1) Consistent with OSM Privacy Policy Privacy_Policy

2) no copyrighted or at least you have written agreement that they give you public data , not covered by copyright or other proprietary clause

3) any thing for community use having Lat , Long coordinates , the question is that OSM has it's own rendering for features and POI look here :


Proposed_Icons and thereof

4) You can propose a new feature , it is submitted to a vote and rejected if other people don't show interest in it.

Q. I woke up this morning to see that most of the secondary roads around my living place are screwed up. It took me hours to fix these roads. The problem show only in the edit page. The view page is still ok. How can i know who did that?

A. The last user who did an edit on a feature can be seen in the Potlatch interface under Layer (the + sign on top right ) window , below maplint choose data then zoom , then look at history in the left window. With Merkaartor click on the node/way and the last change and user name appears in the window Information
