Easy OWL drawing with the graphol visual ontology language

GRAPHOL is a visual language designed to help non-experts to understand and specify ontologies. Our language builds on the Entity-Relationship model, but has a formal semantics and higher expressiveness. Notably, OWL 2 can be completely encoded in GRAPHOL. Thanks to the novel open-source Eddy ontology editor, designers can easily draw GRAPHOL diagrams corresponding to OWL ontologies and export them into standard OWL 2 format. Both GRAPHOL and Eddy have been used in several successful industrial projects and are currently under active development. This paper reports on our more recent progresses.
