Good that RDF4J goes "quad first"!
That would simplify a lot both here and in jsonld-java integration, I
agree. However `Triple` is where we started and also a prime type in Jena. RDF
1.1 does not really define a 'quad' as much as it defines a "triple". Also many
non-expert users are likely to just want to stay at the RDF graph level and
could be confused if their 'contains' call fails.
And so I think we should still support triples and graphs for the RDF4J
integration.
