Hi ajs6f, yes, what I am aiming for is what the FROM statement would do if it could target graphs outside my own dataset.
The only thing I have come up with so far - as an idea, not tested - is loading the RDF file into a named graph, querying it and then dropping it again. What I am asking is whether there is a simpler way of instructing Fuseki to temporarily load that graph just for the purposes of one query.
