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
]
