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
Discussion:
Q: where do you get the class info for the relational data A: (it directly talks about it, thus) starting at load time, have ontol for
a table
A to Q: indexing is done at time of bulk load
