The Transformation Tool Contest (TTC) workshop is going into its 6th round! This year it will be co-located with ICMT and other conferences and workshops as part of STAF. The aim of the TTC 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.
The Eclipse-based portion of the tools participating at the TTC is continuously increasing. At the TTC 2011, we had some great solutions of many EMF and Eclipse-based transformation tools, including Edapt, Epsilon, Henshin, MDELab, VIATRA2 and others. Maybe your tool should be in that list too!
This year we have three great cases to be solved by you: a Flow Graphs case (submitted by Tassilo Horn), a Class Diagram Restructuring case (submitted by Kevin Lano and Shekoufeh Kolahdouz Rahimi), and a
Petri Nets to State Charts case (submitted by Pieter Van Gorp and Louis Rose). If you want to learn more about these cases, take a look at the introduction video by Louis Rose.
Hope to see you at the TTC 2013!

Henshin 0.9.6 released
We are happy to announce the release of version 0.9.6 of Henshin. If you don't know it yet, Henshin is a model transformation language for the Eclipse Modeling Framework (EMF) and is based on visual graph transformation rules. Below, you see two pretty much self-explaining example transformation rules in Henshin.
The Henshin transformation language itself is defined in EMF and provides you with powerful concepts including declarative rules, imparative control-flow constructs and attribute calculations in JavaScript. Transformations are executed using an interpreter engine with a stable light-weight API and can be analyzed using state space generation tools and a profiler.
Henshin 0.9.6 comes with lots of improvements in the graphical and the tree-based editors, including support for different color modes (essentially themes). Both the transformation language and the interpreter API are stable and thus fully backward compatible. The interpreter itself now understands expressions like "[a,b,c]" for multi-valued attributes. All in all, I think we are on a good way towards version 1.0!
