Yes, I'm matching based on the coordinates in Wikidata and OSM, the
coordinates need to be within 400m of each other.

I don't think there is a license problem. I'm not planning to copy location
information from Wikidata to OSM, just establishing the mapping between OSM
and Wikidata.

I think a good comparison is there various ref:*=* tags.
See http://wiki.openstreetmap.org/wiki/Key:ref#Key_variations

We use keys like ref:mhs and ref:sandre to establish a link to other datasets.
There are no rules about the how these datasets were generated.
