The Empirical Modelling research group has designed several definitive notations over the years. The term "definitive" was a pun on "definition-based" from 1986 that stuck. Most of these notations are implemented within the EDEN software tool. See the Introduction: Notes on definitive notations document for more details about what constitutes a definitive notation.
