Model transformation language

A model transformation language in systems and software engineering is a language intended specifically for model transformation.

Overview 
The notion of model transformation is central to model-driven development. A model transformation, which is essentially a program which operates on models, can be written in a general-purpose programming language, such as Java. However, special-purpose model transformation languages can offer advantages, such as syntax that makes it easy to refer to model elements. For writing bidirectional model transformations, which maintain consistency between two or more models, a specialist bidirectional model transformation language is particularly important, because it can help avoid the duplication that would result from writing each direction of the transformation separately. 

Currently, most model transformation languages are being developed in academia. The OMG has standardised a family of model transformation languages called QVT, but the field is still immature.

Available transformation languages 
 ATL : a transformation language developed by the INRIA
 Beanbag (see ) : an operation-based language for establishing consistency over data incrementally
 GReAT : a transformation language available in the GME
 Epsilon family (see ) : a model management platform that provides transformation languages for model-to-model, model-to-text, update-in-place, migration and model merging transformations.
 F-Alloy : a DSL reusing part of the Alloy syntax and allowing the concise specification of efficiently computable model transformations. 
 Henshin (see ) : a model transformation language for EMF, based on graph transformation concepts, providing state space exploration capabilities
 JTL : a bidirectional model transformation language specifically designed to support non-bijective transformations and change propagation (see ).
 Kermeta : a general purpose modeling and programming language, also able to perform transformations
 Lx family (see ) : a set of low-level transformation languages
 M2M is the Eclipse implementation of the OMG QVT standard
 Mia-TL : a transformation language developed by Mia-Software
MOF Model to Text Transformation Language: the OMG has defined a standard for expressing M2T transformations
 MOLA (see ) : a graphical high-level transformation language built in upon Lx.
 MT : a transformation language developed at King's College, London (UK) (based  on Converge PL)
 QVT : the OMG has defined a standard for expressing M2M transformations, called MOF/QVT or in short QVT.
 SiTra  : a pragmatic transformation approach based on using a standard programming language, e.g. Java, C#
 Stratego/XT : a transformation language based on rewriting with programmable strategies
 Tefkat : a transformation language and a model transformation engine
 Tom : a language based on rewriting calculus, with pattern-matching and strategies
