Hi folks,
I was checking the map, and the current map seems a bit skewed.
Kosovo has been recognized as a country for a while now, and to my understanding that should be okayish to have its boundary. The reference to the wikipedia article suggests that too. Where can we read about the country boundaries? I am sure there is some reason for this 
The boundary for Kosovo is present in the database and it does render on the map. However, you’ve linked to two specific versions of the boundary relation in the database’s revision history. It’s a bit confusing, but we track both the history of the world and the history of what we’ve mapped so far. Each time someone edits a boundary, a new version is recorded in the database, even if nothing has changed in the real world. When a boundary does change in the real world, we create a new relation to represent it.
Unfortunately, the page for a specific version of an element normally doesn’t highlight that element on the map and doesn’t automatically move the time slider to a date within the element’s time span. If you click the “Relation” link at the bottom of the sidebar, it takes you back to the relation’s main page, which will let you visualize the boundary.
Yes, sure - sorry, not very clear what I was suggesting.
I think the place=region should be set to place=country so that when it gets rendered, it gets rendered as a country, which it is.
Updated title to show that.
I probably do not have the rights to tag that, as i can see that I can contribute only with new places if I zoom in.
Ah, sorry for the confusion. Yes, I see now that the boundary relation was originally tagged as admin_level=2 and place=country, but it was changed to admin_level=4 and place=region a few years ago. There likely wasn’t any discussion about it at the time. We probably didn’t notice because OHM’s coverage of even present-day countries was so incomplete at the time.
Instead of relegating the “factual” situation to a note=*, we should probably follow OpenStreetMap’s approach to modeling this geopolitical dispute: tag it as admin_level=2 place=country again, based on the de facto situation, but add a disputed_by=* tag indicating that several countries disagree.
You do have permission to edit the boundary relation. If you aren’t able to make this change in iD, it’s probably because you’re zoomed out too far. Go to the relation’s main page, then click Edit. You’ll see a banner saying you have to zoom in, but the details will be editable in the left sidebar. If not, you can also enter the relation ID into the search bar to force the relation to load. Note that the place=* tag may not be visible by default in the sidebar. You’ll have to expand the Tags section to see it.
Super, someone fixed it already when I went to check it!
Still main language in OpenHistoricalMap seems Serbian, while OSM suggests Albanian, and actually main official language is Albanian (shared in Wikidata).
If you mean cities like Ferizaj/Uroševac, there are two issues:
name:al=*, using a nonexistent language code. The correct key would be name:sq=*.name:sq=* tag, or if your preferred language is set to something else like English that isn’t tagged yet, the map falls back to the name=* tag, which is supposed to represent the contemporary local language (could be the official language, but not necessarily; it depends on the country). If Albanian is the most relevant language, the name=* tag should be in Albanian. If both Albanian and Serbian are equally relevant, then name=* should contain both names separated by a semicolon.I was just looking at Kosovo on the map, and was shocked to see that Montenegro only became independent in 2006. I always knew Kosovo was a new country, but I never knew that Montenegro was almost as new.
Yeap - I think the main difference is how they became independent and what is their current relationship - so it is less problematic as an issue Montenegro’s independence in the international arena - so less complex narrative.
