Re: [OWLAPI-developer] How to create enumeration in ontology?

[Randy K. <rk...@sa...>]

You need to add an EquivalentClasses Axiom to equate the Named OWL Class Color to the ObjectOneOf ClassExpression.

To what you had before, add something like the following:

OWLOntology ontology = ....;
OWLClassExpression c = f.getOWLObjectOneOf( .... );

OWLClass colorClass = f.getOWLClass( IRI.create( "http://example.com/ex.owl#Color" ) );
OWLAxiom ax = f.getOWLEquivalentClasses( colorClass, c );
manager.applyChange( new AddAxiom( ontology, ax ) );

(Note: I'm just typing freehand into email message, so typos are possible)
