This is to call you attention to the tool contest, which is part of
the ICGT 2008 workshop on Graph Based Tools (GraBaTs):
http://www.fots.ua.ac.be/events/grabats2008/

Today, we selected three case studies out of ten submitted ones:

• a refactoring case study,
• a transformation performance and visualization case study,
• a translation case study.

Until July 11, you can work on your solution to one or more of these
case studies and submit it along with a brief description to
http://www.easychair.org/conferences?conf=grabats2008

After the workshop, we will use this contest as the basis for a
journal special issue. Although we will invite the complete
transformation community for submitting an article on the contest, you
are strongly encouraged to start working on your solution now and
present/compare it at the GraBaTs workshop.

GraBaTs 2008 Tools Contest: Call for Solutions

4th International Workshop on Graph-Based Tools: The Contest
Part of ICGT 2008: http://www.cs.le.ac.uk/events/icgt2008/
Contest Homepage: http://www.fots.ua.ac.be/events/grabats2008/

Tools are crucial for the promotion of graph transformation in
industry. Currently, a number of tool environments for different graph
transformation approaches are around. Though there have been some
comparisons, it is still difficult for newcomers to decide for the
right graph transformation tool to use for their
application. Moreover, for most of the tool experts it is true that
they know much about one or two tools but little about the others,
whereas they could actually learn from and be inspired by one another.

The aim of this event is to compare the expressiveness, the usability
and the performance of graph transformation tools along three selected
case studies. In this way, 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 transformation tools and to indicate open problems.

The event is the second of its kind: the first graph-based tool
contest took place as part of the AGTIVE 2007 workshop in Kassel,
Germany.

Phase 2: Case solutions

Three contest cases are published at
http://www.fots.ua.ac.be/events/grabats2008/ (see "Cases"). All those
who like to participate in the contest are asked to choose one or more
case studies, take their favourite graph transformation tool and
submit their solutions. A submission should consist of a description
of the chosen case study variant (if any) and a presentation of the
chosen solution, including a discussion of design decisions. Solutions
are to be submitted by July 11, 2008, to
http://www.easychair.org/conferences?conf=grabats2008.

Depending on the number of submissions, a selection will be made of
solutions to be presented; the other submissions will get a chance for
a (non-plenary) tool demo at the end of the workshop. In addition, it
is planned to have a special journal issue where submitters have a
chance to improve and write up their solutions.
