Project Overview

The main objective of the VIATRA2 (VIsual Automated model TRAnsformations) framework is to provide a general-purpose support for the entire life-cycle of engineering model transformations including the specification, design, execution, validation and maintenance of transformations within and between various modeling languages and domains.

VIATRA2 intends to complement existing model transformation frameworks in providing

  • a model space for uniform representation of models and metamodels
  • a transformation language with
    • both declarative and imperative features
    • based upon popular formal mathematical techniques of graph transformation (GT) and abstract state machines (ASM)
  • a high performance transformation engine
    • supporting incremental model transformations
    • trigger-driven live transformations where complex model changes may trigger execution of transformations
    • handling well over 100,000 model elements (see our benchmarks)
  • with main target application domains in
    • model-based tool integration framework
    • model analysis transformations

    VIATRA2 Milestone 3.2 has been uploaded to our secondary update site. The milestone notes can be found on the Eclipse Wiki, as always.
  • April 4th 2011
    We are proud to announce the EMF-IncQuery project, a spin-off of VIATRA2 to bring the incremental pattern matching technology to EMF models. With EMF-IncQuery, you can re-use your VIATRA2 pattern definitions in a pure EMF technology environment, will all the advanced features of the VIATRA2 pattern matching engine (i.e. automatic update propagation through ResourceSets, and delta monitors for high level change detection). EMF-IncQuery is available as open source software under the EPL v1.0 from http://viatra.inf.mit.bme.hu/incquery
    EMF-IncQuery also features a generic EMF importer for VIATRA2, which can be used to import EMF meta- and instance models into VIATRA2 model spaces.
