If the resource returned by listClasses() has a URI, then you can use =20=

$ontModel->createOntClass($uri) to retrieve a matching OntClass =20
object. I don't know if it is possible with an anonymous class.

OntModel also has createOntProperty and createIndividual methods.

Hope that helps,
Richard
