Ontology IRI and version IRI

Public Functions

bool cowl_ontology_id_equals(CowlOntologyId lhs, CowlOntologyId rhs)

Equality function.

Note

Ontology IDs are considered equal if they have the same ontology IRI and version IRI. Since OWL 2 allows for both the ontology and version IRIs to be simultaneously empty, in that case the ontology IDs are considered different unless they are the same instance.

Parameters

• lhs – LHS of the equality relation.

• rhs – RHS of the equality relation.

Returns

True if the equality relation holds, false otherwise.

ulib_uint cowl_ontology_id_hash(CowlOntologyId id)

Hash function.

Parameters

id – The ontology ID.

Returns

The hash value.
