From Model Versioning to Variability-Augmented Modelling Technologies

Version control systems are an essential part of the software development infrastructure. While traditional systems mostly focus on code-based artefacts, recent trends such as Cyber Physical Systems (CPS) require to support model-based artefacts as well – especially in interdisciplinary settings. As a consequence, several dedicated approaches for model versioning have been proposed recently. In this talk, I will review the active research field of model versioning, establish a common terminology, introduce the various techniques and technologies applied in current model versioning systems, and conclude with open issues and challenges such as the need for variability-augmented modelling technologies.
