Hi Andy, Thanks for your reply.

Remove these. > > Did you load into "http://example.org/bob"; So I used tdbloader2 to store dft.ttl into an empty instance of TDB. I assume this places the data in the default graph? The dft.ttl data looks like this: @prefix dc: <http://purl.org/dc/elements/1.1/> . <http://example.org/bob> dc:publisher "Bob Hacker" . <http://example.org/alice> dc:publisher "Alice Hacker" . Then I used s-put to store bob.ttl and alice.ttl into the named graphs http://example.org/bob and http://example.org/alice respectively. bob.ttl looks like this:- @prefix foaf: <http://xmlns.com/foaf/0.1/> . _:a foaf:name "Bob" . _:a foaf:mbox <mailto:b...@oldcorp.example.org> . and alice.ttl looks like this... @prefix foaf: <http://xmlns.com/foaf/0.1/> . _:a foaf:name "Alice" . _:a foaf:mbox <mailto:al...@work.example.org> . When I run the query though I get no results. > Run this: > > SELECT * { > { ?s ?p ?o } UNION { GRAPH ?g { ?s ?p ?o } } > } > > to see what you have. > > I have this:- -------------------------------------------------------------------------------------------------------------------------------------------- | s | p | o | g | ============================================================================================================================================ | <http://example.org/bob> | <http://purl.org/dc/elements/1.1/publisher> | "Bob Hacker" | | | <http://example.org/alice> | <http://purl.org/dc/elements/1.1/publisher> | "Alice Hacker" | | | _:b0 | <http://xmlns.com/foaf/0.1/mbox> | <mailto:b...@oldcorp.example.org> | <http://example.org/bob> | | _:b0 | <http://xmlns.com/foaf/0.1/name> | "Bob" | <http://example.org/bob> | | _:b1 | <http://xmlns.com/foaf/0.1/mbox> | <mailto:al...@work.example.org> | <http://example.org/alice> | | _:b1 | <http://xmlns.com/foaf/0.1/name> | "Alice" | <http://example.org/alice> | -------------------------------------------------------------------------------------------------------------------------------------------- > > I have tried using the form <http://localhost:3030/my-** >> dataset/data?default <http://localhost:3030/my-dataset/data?default>> >> but this has no affect (although I can download the data from here...) >> > > Longer: > > In TDB it picks FROM/FROM NAMED from the set of already loaded named > graphs. > > http://jena.apache.org/**documentation/tdb/dynamic_**datasets.html<http://jena.apache.org/documentation/tdb/dynamic_datasets.html> > > But it is only from data already loaded.

Are you saying that the default graph is either the data not in named graph or the combination of named graphs? It can only be one or the other? Thanks Rob
