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

Standard conformance

We need to point out that the underlying modeling and transformation concepts of VIATRA2 are nonstandard.

• the model management framework (VIATRA2 Model Space) is more expressive than MOF / EMF,
• the VIATRA2 Transformation Language is not QVT, but combines formal techniques being in use for more than 15 years.

VIATRA2 plans to support related standards by offering

• powerful and extensible model importers and exporters
• exporters/importers of other transformation languages (e.g. QVT)
• domain specific languages integrated to the framework as VIATRA2 (and thus Eclipse) plug-ins.

Known uses

The VIATRA2 framework currently served as a key underlying model transformation technology in various research projects including:

• the DECOS EU FP6 IP in the field of dependable embedded systems
• the SENSORIA EU FP6 IP in the field of service-oriented computing
• the DIANA EU FP6 STREP in the avionics domain
• the HIDENETS EU FP6 IP in the field of vehicular networking.
• the MOGENTES EU FP7 ICT STREP

We regularly received valuable feedback from the following institutes

• Budapest University of Technology and Economics, HUN
• OptXware Research and Development LLC, HUN
• ARCS, Vienna, AUT
• LMU Munich, GER
• TU Kaiserslautern, GER
• Univ. of Pisa, ITA
• Georgia Institute of Technology, USA

Technical Information

Obtaining VIATRA2

VIATRA2 Downloads

Currently, there are two releases of VIATRA2 which are available for download:

• VIATRA2 Release3: the latest and much improved version of VIATRA2. This is the recommended version.
  • CVS: you can pull the sources from CVS (see below).
  • Update site: You can use the following update site URL to get the latest version: http://viatra.inf.mit.bme.hu/update/R3
• VIATRA2 Release2 (provided for historical purposes only)
  • Update site: You can use the following update site URL to get the latest version: http://viatra.inf.mit.bme.hu/update/R2

Sources

VIATRA2 is released under the Eclipse Public License v1.0. There are two ways to obtain the sources:

• Development Subversion repository: You can always check out the current development version from our development subversion repository. SVN repository URLs:
  • https://svn.inf.mit.bme.hu/viatra/
    • viatra_core/R3: R3 core (stable) components (current version)
    • viatra_core/R2: R2 core (stable) components (archived version)
    • viatra_extra/R3: R3 extra (experimental) components (current version)
    • viatra_extra/R2: R2 extra (experimental) components (archived version)

For instance, the current core components repository URL is: https://svn.inf.mit.bme.hu/viatra/viatra_core/R3. For more details on what you can get from the source repositories see VIATRA2/Components.

• Eclipse.org CVS

We synchronize the developer SVN with the official Eclipse CVS on every milestone release. Currently, you can check out VIATRA2 R3 Release Candidate 2 from the CVS repository: http://dev.eclipse.org/viewcvs/indextech.cgi/gmt-home/subprojects/VIATRA2/sources/R3/.

Installation

See VIATRA2/Installation.

Documentation

The official page has details on the available documentation. In short, the following off-line documentation is available:

• User's guide: PDF
• Transformation language specification: PDF
