Demo 1: semantic technology in Oracle DB's

infer new relnsh's from RDF data using RDFS and ... user-defined rules RDF queries query RDF/OWL data and ontologies

simple case: use rulebase "RDFS"

planned directions/soon: - support OWL subsets: a goodly portion of OWL-DL - ontology-assisted query or enterprise data - also bulk load of data

scaling up to millions of triples, WITH inference in RDFS and bigger OWL subset

SNOMED

e.g., jaw, mandible, maxilla, T-11170, T-11180

      a table 

A to Q: indexing is done at time of bulk load
