I see nothing there that enables using a wikidata label in an OSM tag. The only reference to labels is a javascript library that does the API calls for you, which is a completely different usecase. >> I had also mentioned rename issues.

We agree, just a misunderstanding on the wording. All users of the wikipedia tag will have issues with renames. The more meticulous consumers will use the wikidata tag instead, which avoids rename issues. >> Which is why we should keep wikipedia tags (along with the >> human-friendly IDs). > > But as already shown, Wikipedia tags have a higher-rate of link rot. Yes. I'm not saying that wikipedia tags are better. Just that we need to keep them, for better or worse. >> And when both wikipedia and wikidata tags are >> present, we can QA that they are in sync (just like we currently QA >> that website an wikipedia are not 404). > > Who will do that QA? I know Keepright does, and I'd be surprised if Osmose doesn't. >> Speaking of stable ids, how does wikidata handle renames, > > Links from the Wikidata item are updated.

An hypothetical example: a hotel that includes a restaurant. OSM uses two objects from the begining, both linked to the single wikidata article that talks about the hotel as a whole. The restaurant later gets spun off as an independent business and get its own wikidata item (either a split or a new one), but OSM still links to the "hotel as a whole" wikidata item. Does wikidata have some tricks up its sleeve to reliably deal with that kind of problem ? _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
