By running the following RDQL query:
SELECT ?b
FROM <http://www.w3.org/2000/10/swap/test/dt10-premise.rdf>
WHERE
(?a, <dc:title>, ?X),
(?b, <ex:age>, ?X)
USING
rdf for <http://www.w3.org/1999/02/22-rdf-syntax-ns#>,
dc for <http://purl.org/dc/elements/1.1/>,
ex for <http://example/vocab#>
RDFStore returns the following:
$result->{ b } = [ http://www.w3.org/2000/10/swap/test/dt10-premise.rdf#mary
]
