Model Driven Engineering (MDE) is increasingly gaining acceptance in the development of software systems as a mean to leverage abstraction and render business logic resilient to technological changes. Coordinated collections of models and modeling languages are used to describe
applications on different abstraction levels and from different perspectives. In general, both models and metamodels are not preserved from the evolutionary pressure which inevitably affects almost any artifacts, possibly causing a cascade of adaptations which severely affects the modeling languages or the model population.
This talk analyzes the different kinds of co-adaptations which are required, distinguishing among co-evolution in the large and in the small. In particular, the coupling between models and metamodels implies that when a metamodel undergoes a modification, the conforming models require to be accordingly co-adapted. Analogously, whenever a new version of a model is produced, the generated application may require an explicit adaptation of the generated artifacts, especially when specific
assets are not directly reflected by the models and transformations, as for instance when dealing with serialized objects or with page content which is persistently stored in a database.
