App/ontology
From mx Help Wiki
Ontologies in mx are very simple. They consist of user definable terms, relationship types, and relationships among terms. Terms can be tagged. References can be tied directly to terms through definitions, or through tags. Images can be attached to terms using figures.
Use
There is some information on how the ontology is being used here at the Hymenoptera Ontology wiki. A public example of the ontology in use can be found here.
