DogmaModeler
DogmaModeler is a free and open source ontology modeling tool based on object-role modeling. The philosophy of DogmaModeler is to enable non-IT experts to model ontologies with a little or no involvement of an ontology engineer. This challenge is tackled in DogmaModeler through well-defined methodological principles: the double-articulation and the modularization principles. Other important features are: the use of ORM as a graphical notation for ontology modeling; the verbalization of ORM diagrams into pseudo natural language that allows non-experts to check, validate, or build ontologies; the automatic composition of ontology modules, through a well-defined composition operator; the incorporation of linguistic resources in ontology engineering; the automatic mapping of ORM diagrams into the DIG description logic interface and reasoning using Racer; and many other functionalities.
The first version of DogmaModeler was developed at the Vrije Universiteit Brussel.
