If your ontology assertions contain an owl:Ontology assertion giving the URI of your ontology, your ontology will appear in Site Admin → Ontology List.  Otherwise, your ontology assertions will be added to be VIVO and will be fully functional as classes, object properties, and data properties, but will not be associated with a named ontology.

Ontologies added to VIVO should use the .owl file type, and should be written in OWL DL.  Ontologies written in RDF or OWL FULL are not supported by VIVO.
