I meant: "Data Source Ontology" :-)

The "Data Source Ontology" is where NeXT and more recently Entity 
Frameworks have focused their attention. RDF on the other hand, extends 
this concept by adding the ability to go beyond the "Data Source 
Ontology" directly from the RDBMS or by mapping the "Data Source 
Ontology" to a "Domain Ontology".

Phew! Got that sorted :-)
