This composite change will convert a defined class to a primitive class by replacing equivalent classes axioms where the class in question is a class in the equivalent classes axioms to a set of subclass axioms whose superclasses are the set of classes which were originally equivalent to the class in question.

More formally, for a given class A, a set of ontologies S, and a target ontology T, this composite change will remove all equivalent axioms from each ontology O in S where the equivalent class axiom contains A as a 'top level' class (e.g. EquivalentClasses(A, C, D)). For each class, D, that was made equivalent to A via an equivalent classes axiom, a subclass axiom SubClassOf(A, D) will be added to the target ontology T.

This change supports a common pattern of working, where a class is converted from a defined class to a primitive class.

Method Detail

getChanges

public java.util.List<OWLOntologyChange> getChanges()

Description copied from interface: OWLCompositeOntologyChange

Gets the changes which compose this composite change. Once this method has been invoked, it will always return the same list of changes.

Returns:

A list of ontology changes.
