Agree on the purpose of Wikidata but many OSM features (such as buildings) does not have a Wikidata item (only major buildings have one, usually landmarks). I would rather say that as soon as an OSM item has a Wikidata attribute then a QA tool may suggest to move some other attributes in Wikidata where they would be better updated and served (start_date for instance). Otherwise those attributes would be fine if no Wikidata item is associated. The OSM wiki pages of such attributes (e.g. start_date) would suggest to put them in Wikidata if and only if an item already exists there. Yours, LeTopographeFou

How to tag this? Maybe: construction:start_date? +1 (but link to Wikidata instead of [or in addition to] Wikipedia) Most OSM data users only care about what is located where. Very few OSM data users would be interested in historical information such as when a building, a basilica, or an airport began and finished its construction. The actual people who would be interested in such information would look elsewhere instead of OSM and I think Wikidata is an excellent place to document such rich types of information. For example, see the Wikidata item for the Sagrada Família: https://www.wikidata.org/wiki/Q48435 | ||
