Re: Tool for visually creating an ontology?

We are on the way to release ICOM 3, the latest reincarnation an old proof of concept which evolved in the last 13 years or so.
ICOM is an advanced conceptual modelling tool, which allows the user to design multiple ER or UML class diagrams with inter- and intra-model constraints, expressed in a rich view but usable language similar to OCL and relational algebra (based on a very expressive description logic). 
It is the first time I'm advertising the new version - still in beta; I'd be happy to get comments.
