Jean-Sébastien Sottet (Public Research Centre Henri Tudor, Luxemburg) and Hugo Bruneliere (AtlanMod Team – Inria, Ecole des Mines de Nantes & LINA) collaborated and won a prize during the last SoTeSoLa 2012 Hackathon  in August.

The objective of this hackathon was to experiment on innovative Reverse & Re-engineering technologies by using the 101companies initiative as the source context (i.e. the legacy). To this intent, a small solution has been developed and proposed based on several Eclipse Modeling tools, namely MoDisco , ATL , Acceleo  and Xtext .

It implements three different (model driven) reverse engineering scenarios to demonstrate the variety and capabilities of these modeling tools:

• Java model discovery from Java source code (using the MoDisco Java model discoverer) + Simple metrics computation from the obtained Java model (using a model transformation implemented in ATL) + HTML rendering/visualization of these computed metrics (reusing the MoDisco metrics visualization builder implemented with ATL)
• Java model discovery from Java source code (using the MoDisco Java model discoverer) + Refactoring on the obtained Java model (using a model transformation implemented in ATL)  + Regeneration of the Java source code from the refactored model (reusing the MoDisco Java generator implemented with Acceleo) 
• Json model discovery (new model discoverer implemented with Xtext) + Mapping from the Json model to UML2 for simplifying the representation as classes and instances (using a model transformation implemented in ATL)

All these scenarios have been integrated into a single project thanks to the MoDisco framework. Thus, three directly runnable MoDisco workflows are also provided. This solution is fully downloadable from here.
