The Ontology UML Profile

UML profile is a concept used for adapting the basic UML constructs to a specific purpose. Essentially, this means introducing new kinds of modeling elements by extending the basic ones, and adding the new elements to the modeler’s repertoire of tools. Also, free-form information can be attached to the new modeling elements. The Ontology UML Profile extends UML in a standard way to enable ontology modeling in the widely used UML modeling tools.
