AGTIVE 2007 Graph Transformation Tool Contest

In this short paper we describe the setup and results of a new initiative to compare graph transformation tools, carried out as part of the AGTIVE 2007 symposium on "Applications of Graph Transformation with Industrial Relevance". The initiative took the form of a contest, consisting of two rounds: the first round was a call for cases, the second round a call for solutions. The responseto both rounds was very good, leading to the conclusion that this is an initiative worth repeating. There are, however, a number of lessons to be learned; these are summarised here, in order to improve the organisation and the eventual benefits of this type of contest
