Hello,
I've done a big table that summarizes 5 notations used with formal ontologies in OWL: description logics, the syntax of the Protégé editor, the syntax of Owlready2 in Python, and the semantics in first-order logic and in set formula. Useful when working on formal ontologies!
You can download the great table of ontologies in PDF here:
