Bases:
owlapy.abstracts.AbstractOWLOntologyRepresents an OWL 2 Ontology in the OWL 2 specification.
An OWLOntology consists of a possibly empty set of OWLAxioms and a possibly empty set of OWLAnnotations. An ontology can have an ontology IRI which can be used to identify the ontology. If it has an ontology IRI then it may also have an ontology version IRI. Since OWL 2, an ontology need not have an ontology IRI. (See the OWL 2 Structural Specification).
An ontology cannot be modified directly. Changes must be applied via its OWLOntologyManager.
