Are you talking about a construct like this: rr:subjectMap [ rr:subject _:1] This gives the ability to define two TriplesMaps that refer to the same constant blank node. Offhand I don't see why this would be prohibited. The fact that blank nodes are not shared between graphs seems orthogonal to this question. But maybe I am not understanding you right? -David
