I’m surprised any tool will read this at all. owl:class is not defined in any standard. It’s owl:Class (case sensitive).
Also, I’m not sure why you’d do these odd things in your ontology, but Composer is not going handle them well. Asserting a class as its own subclass is not necessary (and will ruin many hierarchy viewers) and a resource being both a class and an ontology has no semantics. Classes are sets really, and an ontology is this according to the standard: > An OWL 2 ontology is an abstract notion defined in terms of the structural > specification.

OWL 2 tools, however, are free to devise other types of > ontology documents — that is, to introduce other ways of physically storing > ontologies. So definitely not a set.
