Hi all, I've got a questions about the interaction of DESCRIBE with GRAPH. Given this setup: # Default graph (stored at http://example.org/dft.ttl) @prefix dc: <http://purl.org/dc/elements/1.1/> . <http://example.org/bob> dc:title "Bob Hacker" . <http://example.org/alice> dc:title "Alice Hacker" . # Named graph: http://example.org/bob @prefix foaf: <http://xmlns.com/foaf/0.1/> . <http://example.org/bob> foaf:name "Bob" . <http://example.org/bob> foaf:mbox <mailto:bob@oldcorp.example.org> . # Named graph: http://example.org/alice @prefix foaf: <http://xmlns.com/foaf/0.1/> . <http://example.org/alice> foaf:name "Alice" . <http://example.org/alice> foaf:mbox <mailto:alice@work.example.org> . <http://example.org/bob> foaf:name "Bobby" . PREFIX foaf: <http://xmlns.com/foaf/0.1/> PREFIX dc: <http://purl.org/dc/elements/1.1/> DESCRIBE ?s FROM <http://example.org/dft.ttl> FROM NAMED <http://example.org/alice> FROM NAMED <http://example.org/bob> WHERE { ?s ?p ?o . GRAPH ?g { ?s foaf:mbox ?mbox } } Would you expect that the description would draw from any graph that had contributed to the result (including the default graph)? e.g. would the description of <http://example.org/bob> be: <http://example.org/bob> dc:title "Bob Hacker"; foaf:name "Bob"; foaf:mbox <mailto:bob@oldcorp.example.org>. or: <http://example.org/bob> dc:title "Bob Hacker"; foaf:name "Bob", "Bobby"; foaf:mbox <mailto:bob@oldcorp.example.org>. or: <http://example.org/bob> dc:title "Bob Hacker". or... I realized that DESCRIBE is somewhat loosely defined, but wondering what other implementations have done in this situation. Any guidance appreciated.... Thanks, Geoff
