I periodically wonder what an RDF without the binary restriction would look like. Would each property/relation have a fixed arity, eg. dc:source might 'be a 4', 'foaf:knows' a 7? That doesn't make a lot of sense to me. So presumably they'd vary freely. In which case, we have a lot of figuring out to do when wondering whether livesWith(alice, bob, 2007, 'y') implies livesWith(alice,bob) or livesWith(alice, bob, 'y', 'foo.html'). The binary straightjacket makes some of these questions impossible, albeit maddeningly... DanReceived on Thursday, 14 January 2010 17:32:16 UTC
