Graphol offers a completely visual representation of ontologies to users, in order to help understanding by people who are not skilled in logic.
Graphol provides designers with simple graphical primitives for ontology editing, avoiding complex textual syntax. Graphol's basic components are inspired by Entity-Relationship(ER) diagrams, thus ontologies that can be rendered as ER diagrams have in Graphol a similar diagrammatic shape.
Graphol allows to express SROIQ(D) TBoxes, thus it is suited for graphically representing OWL 2 ontologies. Through the Eddy Graphol editor one can draw ontologies in Graphol and export them in OWL 2.
