| An ontology identifies the concepts, relationships, distinctions, and constraints that a community recognises within a defined domain. An ontology makes selected semantic commitments explicit. | An ontology identifies the concepts, relationships, distinctions, and constraints that a community recognises within a defined domain.

| An ontology captures selected semantic commitments for a domain. It does not capture all possible meanings associated with the domain. An ontology is not equivalent to [[private:99_annexes:annex-b-terms-and-definitions:o:owl|OWL]]; OWL is one ontology language that expresses ontology content. A governed ontology remains traceable to the conceptual model or other authoritative semantic source that establishes the intended domain meaning. | An ontology captures selected semantic commitments for a domain.
