Ahh .. now were getting to the meat of the issue.
If we do it the way you prescribe above, then yes "A triple is unique". But
my stating now that [Bush wonThe Election] is certainly different from (not
identical to) the Electoral College stating [Bush wonThe Election]. Certainly
the context of utterance is what gives a triple its unique identity. I think
I stand on firm ground when I say that. [Word&Object] So if a triple is to
represent a unique entity ("A triple is unique"), then we would need to
Skolemize the entire node, the nodes to which it arcs and the nodes that arc
to it.
I disagree: a triple is not unique.
