Selecting data using SEM_MATCH

Hi,
 
I try to get index from family example using SEM_MATCH. For example I do
 INSERT INTO family_rdf_data VALUES (3,
 SDO_RDF_TRIPLE_S('family',
 'http://www.example.org/family/Janice',
 'http://www.example.org/family/motherOf',
 'http://www.example.org/family/Suzie'));
 
And now I want do somethink like this
 
SELECT a.id, ?x, ?y FROM TABLE(SEM_MATCH(
 '(?x :grandParentOf ?y) (?x rdf:type :Male)',
 SEM_Models('family'),
 null,
 SEM_ALIASES(SEM_ALIAS('','http://www.example.org/family/')),
 null));
 
to get: id, subject, object

As far as I know SEM_MATCH et al are proprietary Oracle functions and 
not part of SPARQL.
