Eddy

Eddy is a graphical editor for the specification and visualization of Graphol ontologies. Eddy features a design environment specifically thought out for generating Graphol ontologies through ad-hoc functionalities. Drawing features allow designers to comfortably edit ontologies in a central viewport area, while two lateral docking areas contains specifically-tailored widgets for editing, navigating and inspecting open diagrams. Eddy is equipped with design-time syntax validation functionalities which prevents ontology designers from constructing invalid Graphol expressions: feedback on the validity of the expression is given through color coding diagram elements. Eddy also supports the standard profiles of OWL 2, i.e. OWL 2 QL, OWL 2 RL, and OWL 2 EL (to appear). Moreover, to support interaction with third-party tools such as OWL 2 reasoners and editors like Protégé, Eddy is able to export the produced Graphol ontology into an OWL 2 ontology.
