Model Driven Engineering (MDE) advocates the use of Model Transformations (MT) in order to automate repetitive development tasks. Many different model transformation languages have been proposed with a significant tool development cost as common language elements like expressions, statements, ... must be built from scratch for each new language development tools. The Tom language is a shallow extension of Java tailored to describe and implement transformations of tree based data-structures. A key feature of Tom allows to map any Java data-structure to tree based data abstractions that can then be accessed by powerful non-linear, associative, commutative pattern matching. In this paper, we present how this approach can be used in order to develop model transformations, in particular relying on Eclipse Modeling Framework (EMF) based metamodeling facilities. This allows to provide a transformation language at a low cost both for the development of its tools and the training of its users.
