Sorry, I should've been clearer. My search starts with articles in English Wikipedia Categories, I look for the matching Wikidata items, then search OSM for items within 400m that have matching tags. For example 'Category:Castles by country' and 'historic=castle'. I compare the names with some fuzzy matching, if the names match then the two items are the same. The credit for this idea goes to Andy Mabbett (pigsonthewing), I just wrote the code. -- Edward. _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
