I just got an idea that is either insigntful or stupid, and I'm not sure which. Wikidata, it appears, wants to have a single, identifiable thing that can be queried and linked to. Our data are unlikely ever to have such a thing unless it is a relation created for the purpose. (For example, don't put wikidata on a street, put it on a route relation and add the street as a member, because the street could be split/joined/replaced at any time.) That's rather messy, but almost unavoidable, given that our object identity is and must be governed by topology. But then it occurred to me: our idea of 'Wikidata reference Q314159265' is 'the set of objeccts tagged with wikidata=Q314159265'. That set doesn't exist as a first-class object, but isn't that what Overpass is for? Would it work to have links into OSM from Wikidata resolved as Overpass queries, rather than tied to single OSM objects? _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
