How do you link to a wikidata label in an OSM tag ? One that never suffers from renaming ? As far as I know, we can/should only use wikidata ids, which are stable but not user friendly. >> * wikidata objects don't necessarily exist for all wikipedia articles >> we want to use > > Apart from newly created Wikipedia articles, with a Wikidata item not > far behind, the reverse is true. Thanks to all who countered my examples. I see now that, even if wikidata may lag a bit (any stats to define "a bit" ?), there should be a wikidata item for every wikipedia article. >> * For data consumers wanting to show the wikipedia article (by far the >> most common usecase), using the wikipedia tag is much more >> straightforward than using the wikidata tag > > Except when the Wikipedia article has been moved and the old name reused. I had also mentioned rename issues. Why leave that sentense out of the quote and then restate it ? Of course ignoring renames and not taking advantage of the API to find the translated article is a bad thing, and no consumers should do that... But in the real world, most consumers will use the wikipedia tag instead. Because it's obvious, and because a simple regexp-replace will give you the url to forward the user to, instead of having to query so wikidata REST api. And when those consumers eventually encounter an OSM object that has a wikipedia tag but not wikidata, they'll display nothing. Which is why we should keep wikipedia tags (along with the human-friendly IDs). 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). Speaking of stable ids, how does wikidata handle renames, merges and splits on the wikipedia side ? Even in the best-case scenario, it seems that an OSM wikidata tag can drift off-target following reorganisations that are correct from a wikimedia POV but not from an OSM POV. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
