Dear colleagues,

It is our great pleasure to invite you to the next seminar of the “GReTA - Graph Transformation Theory and Applications” series:

     Friday December 3, 15:00 CET
     "Supporting Software Variability with Graph Transformations", D. Strüber
     (abstract, Zoom and YouTube links attached below)

The GReTA seminar series aims to serve as a platform for the international graph rewriting community, to promote recent developments and trends in the  field, and to permit a regular networking and interaction between members of this community. Seminars are scheduled twice a month (cf. for a list of upcoming events).

With best regards,

Nicolas Behr, Andrea Corradini, Jean Krivine and Reiko Heckel

Title: Supporting Software Variability with Graph Transformations


Daniel Strüber (Department of Computer Science and Engineering, Chalmers University of Technology, University of Gothenburg, Sweden)


Software systems and the artifacts they consist of often exist in many different variants. When creating new variants, developers typically rely on the "clone and own" strategy of copying and modifying existing variants, a simple and intuitive approach with significant long-term disadvantages. In this talk, I present a line of work on supporting variants in software engineering by explicitly addressing variability as a feature in graph transformations. I focus on three transformation scenarios: one where the input graph  has variability (representing the established notion of a software product  line), one where rules have variability (leading to variability-based rules), and a combination of the first two scenarios. Each scenario is supported with formal constructions, efficient transformation algorithms, and tool support. Our work shows that a systematic way of supporting variability in transformations can improve the maintainability and the performance of a software system.
