AbstractOWLOntology

Represents an OWL 2 Ontology in the OWL 2 specification.

Module Contents

class owlapy.abstracts.abstract_owl_ontology.AbstractOWLOntology

Bases: owlapy.owl_object.OWLObject

Represents 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).

Nothing.

abstract save(document_iri: owlapy.iri.IRI | None = None)

Saves this ontology, using its IRI to determine where/how the ontology should be saved.

Parameters:

document_iri – Whether you want to save in a different location.
