Just to be crystal clear since it's evidently an issue easy to get confused on, do you think that for two arbitrary graph patterns G1 and G2, should Join(G1, G2) = Join(G2, G1). Where Join/2 is inner/natural/standard join. If so, should the basic connective of graph patterns in SPARQL be Join? My answers are Yes and Yes. This is the answer in SCS. From what I can glean, Andy is in favor a different basic connective (where the above relation isn't always true). (I presume he'd agree that Join obeys the above equality). Cheers, Bijan.
