I am trying to use tdb.tdbquery for the first time (but I am running it via an
Ant script).
I have loaded data into TDB.
I have a few queries that had been working with SDB, but every query I run
returns no results.
I thought maybe the graphs I was referring to in the query were wrong or needed
to be different, I tried several variations, including urn:x-arq:UnionGraph.
I am using an assembler file, which has the models and associated graph names
declared, but they don’t work.
Still no results. Then I tried the following query I found in the Learning
SPARQL book
select distinct ?g
where
{
GRAPH ?g {?s ?p ?o}
}
I thought this would tell me the right graph names to use. But this came back
with no results either.
Any ideas?
