Development of a MDSD-toolchain to replace a legacy system

Initial situation

The obsolete system of the RWE division GI-ADA, driven by Rational Rose as an UML-modelling tool and with a proprietary code generator, should be replaced by a lightweight. In doing so, the existing Rational Rose models and diagrams should be transferred into a new system.

Data migration and new deployment of a MDSD-toolchain

To replace the legacy system, itemis developed a MDSD-toolchain. For this purpose, a written migration tool transferred existing Rational Rose models and diagrams into Xtext-models and GMF-diagrams. The deployed GMF-modelling tool is customized to the needs of the user. Furthermore, the new toolchain is easier to maintain by the Modeling Workflow Engine (MWE) and Xpand based Generator.
