Differencing of Model Transformation Rules: Towards Versioning Support in the Development and Maintenance of Model Transformations

摘要

With model transformations arising as primary development artifacts in Model-driven Engineering, dedicated tools supporting the development and maintenance of model transformations are strongly required. Calculating differences between versions of transformations is an essential service for effectively managing their evolution. In this tool demonstration paper, we present support for this task which is tailored for the differencing of graph-based model transformation rules. Our implementation is based on the model differencing framework SiLift which we adapt to the Henshin model transformation language. We demonstrate the usefulness of this feature using a running example.
