The Open Research Knowledge Graph (ORKG) has some data on science that mirrors some of Wikidata/Wikicite/Scholia's data.
- ORKG is CC0, see https://orkg.org/page/license
- ORKG has a property for Wikidata ID, see, e.g., https://orkg.org/resource/R74653?noRedirect
- There is a query service-like interface at https://orkg.org/sparql/
I would like to be able to make federated queries from the Wikidata Query Service to the ORKG endpoint:
Add "https://orkg.org/triplestore" to
