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

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
