That's not my intention, and it's not what I do. In my case, I treat this as defining: ID => { < a, b, c > < a1, b1, c1 > < a2, b2, c2 > < a3, b3, c3 > } Part of the rationale is based on the equivalence with the quad approach, but you have reminded me that this is a *choice* I made, not an inevitable consequence. BTW, in N3, what do you think this means?: :id :- { :a :b :c . :a1 :b1 :c1 . :a2 :b2 :c2 . } :id :- { :a3 :b3 :c3 . } (all in a single document.) >I've never felt the need for more than {triples} names; >those names are written on documents which have URI's >and those URI's are the pivotal points.
