Specification of UML Model Transformations

The purpose of our research is to evaluate and compare different approaches for the specification, verification and implementation of model transformations, and to make recommendations for a transformation specification language which is modular, verifiable, and supports reuse and implementation. In this paper we survey existing approaches to model transformations and propose a new specification and implementation approach for transformations. We describe case studies, of state machine slicing, and re-architecting systems for achieving quality of service in service-oriented architectures, which are used to evaluate model transformation specification approaches and languages.
