I suspect that some RDF-Query cases aren't expressible in the RDF-Path that I sketched. For example:- ?x foaf:knows ?person . ?x foaf:knows ?anotherPerson . ?anotherPerson foaf:knows ?person . With ?person as the end point. I suppose that since SELECT in RDQL and SquishQL pretty much identify end points, there's nothing that RDF-Path can do that RDF-Query can't. But again, see my previous email for an API approach that wouldn't be possible using RDF-Query--it seems to me that that approach might yield faster results. But I'm not sure. Cheers, -- Sean B.
