Re: A single reifier can reify more than one triple term

Aside from this, I also worry about having to explain an identifier reifying a set of triples vs. an identifier identifying a set of triples (a named graph). I promise that distinction will be lost on many people.
First of all, let’s not call it identifier; reifier is, so far, a better and LESS CONFUSING name.
A reifier is a resource the is unique only in the case the triple term it reifies uniquely identifies it. Whenever the triple term does not uniquely identify a reifier (like in the liz and Richard marriage) then you allow multiple reifiers for the same triple term.
And for any such triple terms not uniquely identifying a reifier, NECESSARILY do exist other triple terms that form another incomplete way to identify a reifier. The union of all those triple terms would completely identify uniquely a reifier, but we can not express this in RDF, which can only express binary predicates.
