Hi mmd,

This type of query, which you suggested, retrieves geolocations of all 
/the wikipedia/, /wikimedia_commons/, and /wikidata/ OSM tags assigned 
to either nodes, areas, or ways. The Overpass API works practically in 
real time, a tag appears in search results after a minute or so.

I implemented it already on the page: http://ausleuchtung.ch/geo_wiki/ 
with marker's direct click-able link to a Wikimedia category, file, 
wikidata and wikipedia page, and a changeable radius of a search down 
from 10 km. In densely populated areas with a lot of Wikipedia articles 
and Wikimedia categories like say London City it makes sense to reduce 
radius of a search.

So now it is possible to see on the map geolocations of the WIkipedia 
articles by coordinates from WIkipedia, and then see geolocations of OSM 
tags /wikipedia/=*, /wikimedia_commons/=*, and /wikidata=* /for the same 

/Some Wikimedia categories have got the coordinates too, for example, 
. I am trying to research now if it is possible to retrieve via the 
Media Wiki API also the geolocations of Wikimedia categories with 
coordinates in order to display them on the map too together with 
Wikipedia articles, but with a marker of a different colour.

Thank you and best regards,
