I think it is very sad that the Taginfo maintainer Jochen Topf has effectively decided not to include information from Data Items. Back then I asked him to unlock the discussion again but he did not even reply to my e-mail. Taginfo also can not handle multiple tags or values documented at one page. This is often helpful to compare tag values. It always expects a wiki page named like “Tag:x=y”. As a result, people created almost empty pages and duplicated information on the wiki side. In case the translation extension is added to the wiki, the wiki markup will change even more.

The current consensus among the wiki editors seems to be not to change existing tag documentation pages in either way. So when I create pages, I write “{{KeyDescription}}” but I do not change existing pages.

The wiki recently experienced a huge traffic increase when overpass.openstreetmap.fr creased to exist and a redirect to its wiki page was created.

Thanks for the notice, I was actually a bit confused when some “unknown” user edited the wiki page of OSM Promotional Material Programme. I was looking for spammers. Well, all the best for you!

Thank you for those insights.

The second diagram shows Switzerland twice. The point at ~7400 unique visitors and 15 survey responses is actually CZ.

Great, that was one of the items on my wish list for 2020. Three down, one to go!
