Henshin is an in-place model transformation language for the Eclipse Modeling Framework (EMF). It supports direct transformations of EMF model instances (endogenous transformations), as well as generating instances of a target language from given instances of a source language (exogenous transformations). Its main features are:
- Support for endogenous as well as exogenous transformations
- Natural treatment and efficient in-place execution of endogenous transformations
- Graphical syntax for transformations
- State space analysis for verification
An alternative visual editor for Henshin has been developed as a student project. See  for more documentation and literature on Henshin and for the update site for the alternative visual editor.
