That's hard to say. Depends on what you're trying to achieve.

RAP can do two things with OWL. There's the ontology API, which lets =20
you load an OWL file and gives you access to the classes and =20
properties and instances in the ontology. There's a tutorial in the =20
documentation. The interesting PHP class is OntModel.

And RAP has two inference engines (forward and backward chaining) =20
that support a (smallish) subset of OWL. The PHP classes are =20
InfModelF and InfModelB.

ModelFactory has some factory methods for all of these.
