Hello, I would like clarification about multiple graph usage if I use quad of TriX for the files I'm loading.
In the release note about Virtuoso 6.1.0 here http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VOSNews#Announcing Virtuoso Open-Source Edition v6.1.0 There is this point : ---------------- Added special code generator for optimized handling of: SPARQL SELECT DISTINCT ?g WHERE { GRAPH ?g { ?s ?p ?o } } ---------------- If I understand it correctly, this should give me all distinct graph in use in the Virtuoso server, but I only get one which is this one: http://www.openlinksw.com/schemas/virtrdf# If I remove the distinct, ---------------- SPARQL SELECT ?g WHERE { GRAPH ?g { ?s ?p ?o } } ---------------- I receive all the graph in the Virtuoso server and like we should expect, some are listed many times. Is this a bug to only receive 1 graph in the first query? You can try it here http://refseq-trig-test.bio2rdf.org/sparql on this sparql endpoint if you want to try an endpoints. with multiple graph Thanks, Marc-Alexandre
