Getting VIATRA2

Refer to the Installation page for instructions on obtaining and installing VIATRA2.

Learning to use VIATRA2

For new users of VIATRA2, we recommend the following introductory material:

VIATRA2 is a Model Transformation (MT) tool. The concept of model transformation is explained in the Model Transformations Intro.
The Using Transformations page presents a tutorial on using existing VIATRA2 transformations. Covers the user interface basics, including an example-guided exercise about loading instance models, exploring the model space, running a ready-made transformation and extracting its output.
The Model Editing page gives an intro on models in VIATRA2. Features a more in-depth introduction to the VIATRA2 model space, including the VPM metamodel, structure, as well as UI support for browsing and editing.

Learning transformation development

Basics concepts of the VIATRA2 transformation language are introduced in the Creating Transformations page.
Afterwards, to learn transformation development, the Hello World tutorial is the place to start. Includes a walk-through of creating and populating a model space with a very simple model, the creation of a "Hello World!" transformation, and two more transformation programs for demonstrating the concepts of pattern matching and model manipulation.
Next, we recommend proceeding to the Case Studies page, where numerous example transformations are showcased. It is especially useful to start with the Activity Diagrams to Petri Nets transformation, which is a very simple tutorial intended for learners, and includes a small exercise.

-Model transformations (MT) are the backbone of the Model-Driven concept. Primarily, MTs are programs that receive as input a '''source model''' that conforms to its '''source metamodel''' and produces a '''target model''' conforming to a '''target metamodel'''. Based on the work of  <ref name="MTSurvey">Czarneck i K., Helsen S.: Feature-based survey of model transformation approaches. IBM Syst .J.  45 (3) (2006) 621-645</ref> MTs are categorised into ''model-to-code'' (M2C) and ''model-to-model'' (M2M) transformation approaches. In general, transforming models to code can be treated as a special case of model-to-model transformations; where a metamodel is provided for the target programming language. However, for many reasons (e.g., reusability) code is usually generated as text rather than its model.

-M2C transformation (a.k.a. automated code generation) is the act of generating source code of an application from high-level models. Automated code generation can be also considered as a special subset of MT yielding textual languages as their target model. Their aim is to simply speed up development, increase code quality, and comply to coding standards. VIATRA2 supports mode-to-code generation in different [[VIATRA2/UseCases/CodeGeneration|ways]].

-Usually, M2M are further categorised into
-* ''Intra model transformations'' , where both the source and the target models are conforming to the same metamodel. A good example for intra MTs are simulations, where the manipulation is taken on the same model.
-* ''Inter model transformation'' , where the source and target metamodels differ. Typical model transformations (e.g., UML-to-RDBMS) are usually InterMTS.
-Both of these transformation categories are supported by the  [[VIATRA2/GettingStarted/GTASMmIntro|transformation language]] of the VIATRA2 framework.
