I just tried your query on a minimal dataset, guessing the structure
from your query. That query gave me results however. Here's the data I
used:
SailConnection connection = sail.getConnection();
URI photo = fa.createURI( "http://test/photo1"; );
URI tagPredicate = fa.creat
Allright, it seems you are using sparql-on-sail and not our integrated
neo sparql-engine. I have quite little experience with that setup, I
must add. Though I don't see why your case shouldn't work, since the
VerboseQuadStore supports all combinations of S P O C. I'm going on

thank you for looking , my query snippet:
try
{
sail.initialize();
Repository repo = new SailRepository( sail );
RepositoryConnection rc = repo.getConnection();
ValueFactory f = repo.getValueFactory();

possible cases, but according to my knowledge a ?S P ?O construct is
supported and tests in the sparql engine verifies that. It can however
depend on what other triple constraints your query has. The neo sparql
engine need

I was testing sail rdf component and I made test store based

like ?x dc:type ?z the query does not returning anything. (I do
have dc namespace prefix). It is work if I do (?x?y?z) or (?x ?
