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

Target Application Domains

VIATRA2 primarily aims at designing model transformations to support the precise model-based systems development with the help of invisible formal methods. Invisible formal methods are hidden by automated model transformations projecting system models into various mathematical domains (and, preferably, vice versa). In this way, VIATRA2 nicely complements other model transformation tools within the GMT initiative.

The most traditional application area for VIATRA2 – started as early as 1998 – is to support the transformation-based dependability analysis of system models taken from various application areas (safety-critical and/or embedded systems, robust e-business applications, middleware, serviceoriented architecture) described using various modeling languages (BPM, UML, etc.) during a model-driven systems engineering process. Such a model (and transformation)-based dependability analysis typically also includes the verification & validation, the testing, the safety and security analysis as well as the early assessment non-functional characteristics (such as reliability, availability, responsiveness, throughput, etc.) of the system under design. In addition, model transformations for specification, design, deployment, optimization or code generation in traditional model-driven systems engineering are also focal areas for VIATRA2.

Standard conformance

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

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:
