It seems clear that DM should generate _:1 <IOU#BORROWER> "Alice". _:1 <IOU#AMOUNT> 10. _:2 <IOU#BORROWER> "Alice". _:2 <IOU#AMOUNT> 10. If that's what the spec says, we are done. There may well be a RDF semantics/SPARQL issue lurking here but that's another matter.

But if we query in SPARQL, we get two different things. Therefore, there is a mismatch between the semantics of SPARQL and RDF.
