I guess the problem we're facing is rather common: Organisation A (in our case, Wikidata) publishes data about some entities and defines an identifier for each entity. Organisation B (in our case, DBpedia) wants to publish additional data about these entities. Does B have to use new identifiers?

Hi everybody, we should focus on features, we can provide: Major Feature 1: loading data for SPARQL queries. This is independent from the URIs and we might use the Wikidata URIs or new ones. Major Feature 2: providing linked data for the data in the store. If we reuse Wikidata URIs, we will
