ROSO — Relationships between classes when referring to other ontologies such as Commons and CORA to be described.

Consider describing the relationship between classes using EquivalentClass, DisjointClass, etc. For example, Robot and Person seem to disjoint parts of Agent. References to Commons or CORA classes may use EquivalentClass.
IEEE RAS, however, does not provide CORA-owl officially. Is it possible to refer them in OWL?
