Hello, I'm glad to can announce my last experiment to work with Wikidata and Wikipedia-coordinates: http://tools.wmflabs.org/wp-world/wikidata/superclasses.php?lang=en

This list shows how many objects we have in different classes and provide links to maps with only this specific class.

I think it's much more useful than in the past where 80% of our coordinates were simply a "landmark".

To create this tool I used properties "is instance of"[1] and "is subclass of"[2]. To extract this properties it was necessary to use "Wikidata Query".

Now all classes, where an object is a member, are in a numerical array-element in the database. So with an index on this array it should have a good performances.

Next steps are to try to bring more order inside this list and support the community to create more "is instance of"-entries in Wikidata. (Only 30% off all objects have such an entry).
