Hi Ruben,

I think if one had a quads interface, you would have to go with a variant of

Maybe also the SPARQL 1.1 Service Description vocabulary could be used here to
provide a description of the RDF dataset exposed by the interface.

Could be, assume it would return SPARQL results formats (XML,JSON,CSV,TSV).
