Practical use of EMF Compare
Abstract
In the Eclipse ecosystem the Eclipse framework (EMF) has been established for modelling. Compare and merge EMF-based models was supported only on a lexical level in XML sourcecode. In this session of our series of lectures, Dr. Lothar Wendehals and Holger Schill introduce the EMF compare framework which uses the logical structure of the models against matching instead.
The EMF compare framework builts a difference model or a matching model that are EMF models as well. This logical level typically also uses a comparison tool which helps the user merge different models.
The first part of the presentation will explain using the EMF compare framework and its basic function. The run-time behavior of different model sizes is examined to show the practical applicability. The second part of the presentation will present the EMF compare tools and the Eclipse integration. To process models, the openArchitectureWare framework has prevailed in the Eclipse environment. It can perform model to text (M2T) or model to model (M2M) transformations using languages Xpand and Xtend.

Holger Schill, Software Architect and Coach
Holger Schill is employed as a software architect and coach for itemis in Kiel. His areas of focus lie in model-based software development and the creation of EMF-based textual and graphical editors for individual DSL's. In various projects Holger Schill applies intensive Xtext and GMF as a hybrid form of modelling.
