Abstract

In model-driven engineering, models constitute pivotal elements of the software to be built. If models are specified well, transformations can be employed for different purposes, e.g., to produce final code. However, it is important that models produced by a transformation from valid input models are valid, too, where validity refers to the metamodel constraints, often written in OCL. Transformation models are a way to describe this Hoare-style notion of partial correctness of model transformations using only metamodels and constraints. In this paper, we provide an automatic translation of declarative, rule-based ATL transformations into such transformation models, providing an intuitive and versatile encoding of ATL into OCL that can be used for the analysis of various properties of transformations. We furthermore show how existing model verifiers (satisfiability checkers) for OCL-annotated metamodels can be applied for the verification of the translated ATL transformations, providing evidence for the effectiveness of our approach in practice.
