“…Among them, we focus on seven complex changes: move property, pull property, push property, extract super class, atten hierarchy, extract class, and inline class. A study of the evolution of GMF 3 metamodel showed that these seven changes are the most used ones and constitute 72% of the applied complex changes [8,14]. In our case study they constitute 100% of the applied complex changes in the evolutions.…”

“…Please note that 30 concurrent changes is significantly higher than the average number of changes per commit according to the case study performed by Herrmannsdoerfer et al [HRW09]. With these versioning scenarios, we measured the steady state performance 6 of AMOR including and excluding the signifier-based merge issue detection.…”

In model-driven engineering (MDE), models constitute the central artifacts in the development process, and thus, are often built by teams of developers. As a consequence, adequate version control for models is crucial to the success of MDE-based projects. Several model versioning systems have been proposed recently. Most of them are generic in the sense that they are agnostic to modeling languages. Although this ensures a wide applicability, important merge issues may not be detected.In this paper, we present an orthogonal extension to generic model versioning systems for enabling the detection of an important subset of language-specific merge issues. Users may enhance the versioning system's capabilities by defining signifiers, which describe the combination of features of a model element type that convey the superior meaning of its instances. Signifiers improve the different phases of the versioning process including comparing and merging models leading to a higher quality of the finally merged models. We showcase the applicability of our approach by enhancing the versioning support for the modeling language Ecore.

“…We call this vertical co-adaptation: Changes need to be propagated from the meta-layer (top) down to the instance layer (bottom). Notable contributions to this kind of co-adaptation came from Wachsmuth [4] and Hermannsdörfer [5].…”

Abstract. Software language descriptions comprise several heterogeneous interdependent artifacts that cover different aspects of languages (abstract syntax, notation and semantics). The dependencies between those artifacts demand the simultaneous adaptation of all artifacts when the language is changed. Changes to a language that do not change semantics are referred to as refactorings. This class of changes can be handled automatically by applying predefined types of refactorings. Refactorings are therefore considered a valuable tool for evolving a language. We present a model transformation based approach for the refactoring of software language descriptions. We use asymmetric bidirectional model transformations to synchronize the various artifacts of language descriptions with a refactoring model that contains all elements that are changed in a particular refactoring. This allows for automatic, type-safe refactorings that also includes the language tooling. We apply this approach to an Ecore, Xtext, Xtend based language description and describe the implementation of a non-trivial refactoring.
