Showcasing Modelio and pure:variants Integration in REVaMP$$^2$$ Project

REVaMP\(^2\) project is part of the ITEA 3 industry-driven Research, Development and Innovation programme in the domain of software innovation. REVaMP\(^2\) project aims to develop automated and comprehensive tools that support massive customizing of “Software-Intensive Systems and Services” (SIS) Product Lines (PL). This approach requires agile round-trip engineering processes for managing the different configurations in legacy assets, and for more systematic and automated variability management. For this purpose, the project puts among its priorities the standardization of a variability language called “Variability Exchange Language” (VEL) as a format for describing variability in models. This paper showcases the integration of the model-driven engineering (MDE) tool “Modelio” with the variability management tool “pure::variants” using the VEL language as data exchange format. VEL is used to model both the feature model, also referred to as “150% model”, with all possible variation points and all variant configurations coming from the features selection for the variant of a specific product.
