Does the inference engine used by Oracle 10g2 have a name? Is it an engine that was developed by a third party? Was it developed by Oracle? If it does not have a name, is it of a specific type? I am not referring to supporting RDF, RDFS or OWL. Someone has asked me if the engine name is Pellet. Any ideas?
The Oracle 10gR2 inference was developed at Oracle. It is not Pellet (which is an open source inference engine).
I am not sure what you mean when you ask whether it is of a specific type. The inference engine at Oracle is a SQL based engine. It supports RDF, RDFS and user-defined rules in 10gR2 and support for OWL is planned in a future release.
