rdflib.Graph is actually a quadruple store. Many users still say
TripleStore because that was the old class name, but most RDF systems,
rdflib included, have grown a concept called "context" a quad-element
that lets you assign context to a triple, sparql calls this the
"source", and some people say that it is used to track the "provenance"
of a triple. Perhaps this is similar to the triadiac relations.

Ok, so in RDF a dyadic relationship is (DocumentURI, dc:title, "Expense
Report"), what would a similar triadic relationship be?
