> StreamRDF seems to mix concepts of triples/quads with tuples of RDF terms. Looking in the codebase, I can't find miuxed uses of triples/quads and tuples of rdf terms (I can't find much use of tuples at all).
> Maybe the abstraction is wrong and StreamRDF shoudl be just triples/quads and have a separate interface (if necessary) for a stream of rows of RDF terms. This would remove the ambiguity of whether a triple is a 3-tuple or not.
