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. > > > But I would guess this would return all statements that are in a named graph > > (rather than the list of graphs), which potentially could be a lot of data. > > Exactly. > > DISTINCT would actually be a nice separate interface feature > that servers might decide to offer to clients.
