Abstract

This paper sketches an approach to the synthesis of provably correct model transformations within the Coq theorem prover, an implementation of Coquand and Huet's Calculus of Inductive Constructions. It extends work done by Poernomo on proofs-as-model-transformations in the related formalism of Martin-Löf predicative Constructive Type Theory. We show how the impredicative theory of Coq, together with its treatment of coinductive types, lends itself to the synthesis of a wider range of model transformations than Poernomo had treated before. We illustrate the practical benefits and potential scalability of our approach by means of a case study taken from industry.
