Model Driven Architecture is an initiative of the OMG that puts a platform and programming language independent modelling using UML in the center of the development. Transformation from high level views to technologydependent views take place more or less automatically through mappings. However, this requires heavy tool support and so far few tools to support this idea adequately exist. In a series of papers an outlook on such tools and the effect on the possibilities for a new generation of Model-Driven Software Engineering processes are discussed. The focus in this paper lies on the execution of models and code generation from state diagrams.
