OWLViz has the facility to save both the asserted and inferred views of the class hierarchy to various concrete graphics formats including PNG, JPEG, and SVG. OWLViz integrates with the Protege-OWL editor, using the same color scheme so that primitive and defined classes can be distinguished, computed changes to the class hierarchy may be clearly seen, and inconsistent concepts are highlighted in red. It enables class hierarchies in an OWL Ontology to be viewed and incrementally navigated, allowing comparison of the asserted class hierarchy and the inferred class hierarchy. OWLViz is designed to be used with the Protege-OWL editor.
