I want to query a Jena model loaded by TDB from an RDF/XML file to get all
subjects whose objects each contains one particular RDFID. I tried the
following SPARQL query and it didn't return any result.
select ?s WHERE
{
?s ?p ?o .
FILTER(CONTAINS(?o, "_{9F750A5B-F02E-4B64-8D78-D0F527ACB900}>"))
}
I guess ?o is a Resource, and there should be some SPARQL function to apply to
"?o" first to extract the RDFID string and then do the "CONTAINS" function, but
I just couldn't find such a function.
Please help!
Thanks a lot!!
