Experiment with a type-theoretic approach to the verification of model transformations

Abstract

"This paper presents ongoing work on the application of constructive type theory for safe development in Model-Driven Engineering. In particular, we put into practice a certification framework based on the Calculus of Inductive Constructions (CIC) as follows: we first describe methods for representing metamodels and specifications of model transformations as types and then outline principles for representing given transformations, written in a certain transformation language, as functions in CIC. Then properties of these functions are proven, including their correctness with respect to sufficiently expressive specifications, thereby providing a semiformal way to verify the original transformations. We carry out a concrete case taken from an on-line base of basic examples and patterns of use of the ATL transformation language, implementing it on machine using the Coq proof assistant." [Abstract]
