Edapt

Due to their high level of abstraction, modeling languages are a promising approach to decrease software development costs by increasing productivity. Significant work in both research and practice has been invested into tool support for the initial development of modeling languages. Over the last years, the Eclipse Modeling Framework (EMF) has become the de-facto standard solution for the development of modeling languages. As modeling languages are more widely used in both academia and industry, their maintenance is gaining importance. Even though often neglected, a language is subject to change like any other software artifact. The languages behind the Graphical Modeling Framework (GMF) for instance -- although relatively young -- have already been evolved due to technological progress or changing requirements. In EMF, a modeling language is evolved by first adjusting its Ecore model to the new requirements. Other artifacts like instances, editors, interpreters and transformations (M2M, M2T) may no longer conform to the evolved Ecore model. Manually migrating these artifacts to the evolved Ecore model is tedious and error-prone, and thus heavily hampers cost-efficient maintenance of modeling languages.
