On the other hand, the hot-staged DBpedia-Live [1] instance does have the partitioning I mentioned and the quickest route to getting graph IRIs is via the /FCT service [2][3]. > >> The SPARQL endpoint will support access to all the data across Named >> Graphs, if your SPARQL patterns aren't scoped to any specific Graph IRI(s). >> Re.
