Also do I need to specify the name of the graphin dbpedia.nq.graph?Its been a lot of days since I have posted at the product support forum(). But I did not find any satisfiable answer. Therefore I am posting here. Hoping someone will help me out.Rose PhD
This is because when processing Quads, the 4th element in the quad is treated as the Graph IRI (which is why your other query returned the expected result). In this case, graph IRI parameter of the bulk loader isn't being used. In this case, we should be using the graph IRI parameter to designate a graph group.
