OWLOntologyID
Objective-C
@interface OWLOntologyID : NSObject <NSCopying>
Swift
class OWLOntologyID : NSObject, NSCopying
An object that identifies an ontology.
Since OWL 2, ontologies do not have to have an ontology IRI, or if they have an ontology IRI then they can optionally also have a version IRI. Instances of this OWLOntologyID class bundle identifying information of an ontology together. If an ontology doesn’t have an ontology IRI then we say that it is “anonymous”.
