But these, um, authorities all disagree. The Wikipedia article seems to suggest that naming a graph is done by http resolving to a graph document, for example. That has squat to do with SPARQL datastores. Some of the authorities (including the SPARQL specs themselves) reference the old article which I helped co-author; some of these follow the terminology used there, others use it entirely differently or ignore it altogether. The meaning of 'named graph' even changes between implementations of the same specifications. In a situation like this, established practice needs to be fixed, not emulated.
