one RDF1.2 "stated" 4-tuple per LPG edge

Converting an LPG edge to RDF1.2 will be simpler to think about, IMO, if we go with use of only a single "stated" id-s-p-o tuple compared to the alternative of using a "reified" id-s-p-o tuple along with an (asserted) s-p-o triple:

LPG edge:
        (s) -[id:p]-> (o)

RDF1.2:
        id rdf:states <<( :s :p :o )>> .
vs.
        :s :p :o .
        id rdf:reifies <<( :s :p :o )>> .
