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
VIATRA2 intends to complement existing model transformation
frameworks in providing
- a model space for uniform
representation of models and metamodels
- a transformation language
- 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

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.
