VIVO includes several ontologies that are not in common use and may be outside VIVO scope. These ontologies should be identified, and then prepared as distinct ontology modules outside vivo.owl that can be loaded by sites if desired. Modules outside the usual domain of scholarship will be identified.
This analysis should be distinguished from "rare" ontological assertions involving ontologies outside the VIVO ontology (such as the event class). These will continue to be included with the VIVO ontology. They are required to make assertions about scholarship.
