Linking RMLibrary to ECARTICO/Wikidata

[LvanWissen]

We need a linkset between the RMLibrary dataset and ECARTICO. Wikidata can serve as a hub and already has many references to both datasets, but this needs to be extended.

At this moment, there are 776/1999 persons with an URI on https://id.rijksmuseum.nl/ in this dataset linked on Wikidata (property P7444), and thereby sometimes to ECARTICO (property P2915) and the NTA (property P1006).

Query on endpoint https://sparql.goldenagents.org/sparql, or through https://api.triplydb.com/s/IwdLzxjNS for every Person resource that is referred to by Wikidata:
