Armando, all, thanks, let's discuss this. I attach the latest version of the OWL ontology and the diagram. Please reviews the definitions of the concepts in the ontology. Talk to you in a few minutes, Philipp. Am 28.06.13 13:03, schrieb Armando Stellato: > > Dear all, sorry for the silence of these last days.. > > ...I would make things more complicate by adding a few things on the > discussion :-) > > First of all, I would reply on the commitsTo.
