Motivation

3Jürgen Walter: Automated Transformation of Descartes Modeling Language to Palladio Component Model

Benefits Transformation• Tooling can be reused• Improves understanding of differences• Flexibility to change

Benefits Automation• Automated transformation is faster, less error-prone and less expensive compared to manual

extraction

Project Overview

•Tooling has to be developed for each formalism•Comparison challenging•Manual transformation error-prone and time consuming

Problem

•Model transformation of DML to PCMIdea

•Reuse of existing PCM tooling for DML• Improved understanding of differences and similarities•Simplified change of formalism

Benefit

• Implement a model-to-model transformationAction
