Hi!
Dear Wikidata developers and contributors,
I see that it is currently not possible to run federated queries from wikidata to other sparql endpoints. I understand why you are not allowing this in the general case. However, it would be nice to allow this in the special case.
Would a patch allowing limited known remote sparql endpoints to org.wikidata.query.rdf.blazegraph.WikibaseContextListener be possible?
Technically, it is possible and shouldn't be very hard to do. We need to figure out which endpoints we want to allow.
What do we need to take into account to figure this out? What are the constraints/concerns/etc? During the last weeks several people said they'd like to see this happen and I think we should explore this more if possible.
Cheers Lydia
