Taming EMF and GMF using model transformation

Abstract

EMF and GMF are powerful frameworks for implementing tool support for modelling languages in Eclipse. However, with power comes complexity; implementing a graphical editor for a modelling language using EMF and GMF requires developers to hand craft and maintain several low level-interconnected models through a loosely-guided, labour-intensive and error-prone process. In this paper we demonstrate how the application of model transformation techniques can help with taming the complexity of GMF and EMF and deliver significant productivity and quality benefits. In particular we demonstrate EuGENia, a widely-used tool that adopts a single-sourcing approach and advanced model transformation techniques for automatically producing and maintaining the low-level models required by EMF and GMF. We evaluate EuGENia through automated testing and substantial feedback from researchers and practitioners within the Eclipse modelling community.
