Aims and scope

Tools are crucial for the promotion of graph and model transformation in industry. Currently, a variety of tool environments exist for different graph and model transformation approaches. These tools have already been compared in some detail. However, for potential users, working in application domains where transformation techniques may be a useful, it is difficult to select the right tool for their purpose. Moreover, even for most of the tool experts it is true that they know about one or two tools but little about others. Finally, and maybe most importantly, the tool developers themselves can also be inspired by a more detailed understanding of related approaches.

The aim of this event is to compare the expressiveness, the usability and the performance of graph and model transformation tools along a number of selected case studies. That is, we want to learn about the pros and cons of each tool considering different applications. A deeper understanding of the relative merits of different tool features will help to further improve graph and model transformation tools and to indicate open problems.

This workshop is the fifth in a series. Previous editions were:

  1. 2002: 7-8 October 2002, Barcelona, Spain (Satellite of ICGT 2002)
  2. 2004: 28 September-2 October 2004, Rome, Italy (Satellite of ICGT 2004)
  3. 2006: 21-22 September 2006, Natal, Brazil (Satellite of ICGT 2006)
  4. 2008: Leicester, 7-13 September 2008 (Satellite of ICGT 2008)
However, at the 2008 edition we have chosen a radically different format (see below), involving a much more active and hands-on approach. We believe that this makes the workshop more suitable for a broader audiance, not restricted to pure graph transformation; hence the proposal to hold the fifth workshop edition as a satellite of the TOOLS federation of conferences instead.

An upcoming special section of the STTT journal will include the case descriptions and most prominent solutions to these cases. Given a sufficient number of submissions, we will organise the same for GraBaTs 2009.

This year, we continue in the new direction from 2009: we plan a combination of submitted solutions to a pre-defined set of problems, with a live contest session. That is, the workshop will feature a session where contenders may use their tool of choice to model a problem that is handed out at the beginning of the day. In addition there will be presentation sessions in the afternoon, where both the submitted solutions to the predefined problem and the live solutions will be presented.
