Hmmm, if a quad store simply establishes an additional link for
a context (or some other entity), then why could we not use the
predicate mechanism of a triple store to access the 4th link?
Must we also standardize on predicates? (02)
Since RDF handles n-ary graphs using blank nodes, why couldn't
quad-graphs also be handled with blank nodes (with an appropriate
predicate)? (03)
