GMF: A Model Migration Case for the Transformation Tool Contest

Using a real-life evolution taken from the Graphical Modeling Framework, we invite submissions to explore ways in which model transformation and migration tools can be used to migrate models in response to metamodel adaptation.Comment: In Proceedings TTC 2011, arXiv:1111.440

Operation-based versioning of metamodels with COPE

Model-based development promises to increase produc-tivity by offering modeling languages tailored to a specific domain. Such modeling languages are typically defined by a metamodel. In response to changing requirements and tech-nological progress, the domains and thus the metamodels are subject to change. Manually migrating existing models to a new version of their metamodel is tedious and error-prone. Hence, adequate tool support is required to support the maintenance of modeling languages. COPE provides adequate tool support by specifying the coupled evolution of metamodels and models. In this paper, we present the tool support to record the operations carried out on the meta-model directly through an editor. These operations can be enriched by instructions on how to migrate corresponding models. To further reduce migration effort, COPE provides high-level operations which have built-in meaning in terms of the migration of models.

Towards a generic operation recorder for model evolution

There are two basic kinds of approaches to track model evolution: State-based approaches derive the changes by comparing model versions, whereas operation-based approaches record the changes when performed on the model. The more accurate changes allow operation-based approaches to better support various use cases of model evolution. However, operation-based approaches are not very widespread in both industry and research, as extensive tool support is required to record and persist the changes. To lower the barrier for building tool support for operation-based approaches, we propose a generic operation recorder. The operation recorder covers a number of use cases and is both customizable and extensible. The implementation of the operation recorder is based on the widely used Eclipse Modeling Framework (EMF)
