Protege is probably running the DL reasoner behind the scenes all the time. Composer does not do that. Best just create the relation yourself and store it. No reason to infer it since it’s in the ontology. > Furthermore, if I define an instance under class A have the property C, it > won't even appear in the "incoming reference" section of class B. > > All equivalentClass inference does is add a rdf:type statements. It means all instance of A are also all instance of B and all instance of B are also instance of A.

Simple equilvalentClass statements are within the OWL RL profile though, so you could use the TB OWL RL profile implemented using SPIN rules to make inferences but those are "on-demand", not "all the time". If your data is based on one ontology, I’d just make the class in that ontology a subclass of the class in the other and then simple rdfs inferencing (which Composer does run) handles your problem. That way the second ontology is more or less a “view” over the first ontology and its data.
