All,
Cleaner version of the SKOS based example re. new Virtuoso Inference
Rules capabilities.
In my last post I had a potentially confusing entry for grabbing the
SKOS ontology (which isn't required and commented out).
The entry is removed from this version
## Cleanup
CLEAR GRAPH <urn:owl.test2.tbox>
CLEAR GRAPH <http://turnguard.com/virtuoso/test10.rdf>
##Load Instance Data into Quad Store
## PL Procedure
-- SQL realm
DB.DBA.RDF_LOAD_RDFXML (http_get
('http://www.w3.org/2009/08/skos-reference/skos-owl1-dl.rdf'), 'no',
'urn:owl.test2.tbox');
DB.DBA.RDF_LOAD_RDFXML (http_get ('http://www.w3.org/2002/07/owl.rdf'),
'no', 'urn:owl.test2.tbox');

##Transitivity Query re. SKOS concept hierarchy
DEFINE input:inference "urn:owl.test2.rules"
