UML Style Graphical Notation and Editor for OWL 2

Conference paper
Part of the Lecture Notes in Business Information Processing book series (LNBIP, volume 64)


OWL is becoming the most widely used knowledge representation language. It has several textual notations but no standard graphical notation apart from verbose ODM UML. We propose an extension to UML class diagrams (heavyweight extension) that allows a compact OWL visualization. The compactness is achieved through the native power of UML class diagrams extended with optional Manchester encoding for class expressions thus largely eliminating the need for explicit anonymous class visualization. To use UML class diagram notation we had to modify its semantics to support Open World Assumption that is central to OWL. We have implemented the proposed compact visualization for OWL 2 in a UML style graphical editor. The editor contains a rich set of graphical layout algorithms for automatic ontology visualization, search facilities, zooming, graphical refactoring and interoperability with Protégé 4.
