How can we make SEM_MATCH return the original inserted type?

CREATE TABLE test_delete_data (id NUMBER, triple SDO_RDF_TRIPLE_S);

EXECUTE SEM_APIS.CREATE_SEM_MODEL('test_delete', 'test_delete_data', 'triple');

INSERT INTO test_delete_data values (1,
  SDO_RDF_TRIPLE_S('test_delete',
  'http://example.com/a',
  'http://example.com/someProp',
  '"750"^^http://www.w3.org/2001/XMLSchema#nonNegativeInteger'));
commit;

The SEM_MATCH does not return nonNegativeInteger

SELECT s, p, o, o$RDFLTYP, o$RDFVID
FROM TABLE(SEM_MATCH(
  '{ ?s ?p ?o }',
  SEM_Models('test_delete'),
  null,null,null));

Outout:
http://example.com/a
http://example.com/someProp
750
http://www.w3.org/2001/XMLSchema#decimal
6.1687E+18


It is returning the canonical type
