Compare coordinates with Wikidata

If the coordinates in Wikidata vary wildly from those in OSM, issue a warning.

Hmm and what if its position is known for sure, but Wikidata has the wrong coordinates? I ran into this multiple times.

"what if its position is known for sure, but Wikidata has the wrong coordinates?"

A warning should sill be issued. We can never know, programmatically which are correct, and should the error be in Wikidata, it still requires fixing.

I was thinking that the plugin could update the Wikidata location from OSM. Of course, it would require Wiki registration.

Just an idea, what do you think?

Is this possible with ODbL?

I think yes. OSM is ODbL, while Wikidata is CC0. See here ​https://wiki.openstreetmap.org/wiki/Import/ODbL_Compatibility

Sorry, that is the opposite way (CC0 -> ODbL) but I asked about OSM to Wikidata (ODbL -> CC0) which is likely to fail as OSM has to be mentioned as source.

You can mention OSM in the location/position item as the source. Isn't it enough?

This might work for the website but I doubt this will work for the api.

Reading the mention wiki page, I stumbled over following in the first paragraph:

Note that while declared license of dataset may be compatible there may be still problems due to different jurisdiction and/or ignoring copyright issues. For example, Wikidata declares itself to be CC0 but includes location data copied from Google Maps, OpenStreetMap and other copyrighted sources.

and ​this wiki section. Seems there are even problems with the source and correct license of the location on wikidata, atm.
