Another, small but significant, data donation secured from the BBC was a set of "BBC Thing" identifiers for news topics (for example, this one for Iran). Added to Wikidata using P1617 (BBC Things ID), they plug the relevant items more tightly into the web of semantic, linked, open data (here's the same ID's BBC linked data for Iran).
Coordinates on Russian Wikipedia now link to maps generated with the Kartographer extension. The map includes the location outline, if that object exists in OpenStreetMap (OSM) with a corresponding Wikidata ID (ways and relations only, not nodes). Example: w:ru:Зальцбург (click coordinates in the upper right corner, or in the infobox on the side). If you create a Wikidata item about a specific administrative area, building, or other physical individual object which appears on maps, then please add the Wikidata ID to the relevant object in OSM, using key:wikidata= (here's how to contribute to OSM).
