EDEN is the Engine for DEfinitive Notations. It is the primary software tool of the Empirical Modelling research group. We build models with it, using a variety of definitive notations that it implements.

It has been developed since 1987 by a succession of four primary authors, and is now available for Windows, Mac OS X and Linux.
