On the concurrent versioning of metamodels and models
Antonio Cicchetti, Federico Ciccozzi, Thomas Lévêque, Alfonso Pierantonio · 2011
Model-Driven Engineering aims at shifting the focus of software development from coding to modelling in order to reduce the complexity of realizing nowadays applications. In this respect, models are expected to evolve due to refinements, improvements, bug fixes, and so forth. Because of the same reasons, also modelling languages (i.e. metamodels) are expected to be changed, even though at a different speed if compared to models. The relevant corpus of research grown up in the latest years and dealing with both these problems considers them as separate events; however, in normal practice not all the models are migrated instantaneously due to a metamodel adaptation, rather the co-adaptation is required when commits are attempted from a local workspace to the model repository, which can demand for different management policies.
