Errr, actually, the first use of insertion of different triples into different graphs jumped up and bit us today... :-) We have a batch edit function in the app to change multiple properties of many resources in one operation. Up to now, we have had one query for each resource, but today we found that it results in too many OPTIONALs, and the query takes forever, so we decided to split it up by property instead, which results in much more manageable queries. However, the instance data that's manipulated here comes from many different archives, and each of them is given a graph name. So there we have the use case... :-) Whether we should accommodate for it is of course an open question. Then, the problem is which graph the triples should be inserted into. In our case, they should be inserted into only the graph that allready contains the subject of the triple. I don't know if this it solveable today with GRAPH in the WHERE clause, or if this introduces additional problems.
