Scope and Objectives
of the Workshop

Effective applications of visual modelling techniques require tool support at a semantic level, e.g., for model analysis, transformation, and consistency management. Due to the variety of languages and methods used in different domains, an engineering approach is required which allows for the generation of such tools from high-level specifications.

Graph transformations provide means to specify, at a conceptual level, complex operations on diagrams. Complementing this by techniques like
  • meta modelling (including OCL)
  • compiler construction
  • logic and algebraic semantics
the workshop aims to bring together researchers from different communities to discuss their respective contributions to different aspects of modelling and modelling languages, like
  • syntax and well-formedness,
  • static and dynamic semantics,
  • analysis and verification,
  • refinement and transformations, and
  • integration and consistency of models.


This workshop is the fourth in the series of GT-VMT workshops:

Program Committee

The PC consist of members of the graph transformation community and external experts for complementary techniques and application areas.


Electronic paper submission is closed.

Authors are invited to submit extended abstracts of 5 to 10 pages in ENTCS format. The submission works in two stages:
  1. register your paper with title, authors, abstract, etc. by December 19, 2003
  2. upload the file to a link sent to you after the registration until December 29, 2003
Contributions should report about ongoing research in the areas of graph transformation and visual modeling techniques according to the scope and objectives of the workshop. Position papers and contributions making methodological statements are strongly encouraged.

Accepted contributions will appear in an issue of Elsevier's Electronic Notes in Theoretical Computer Science. A preliminary version of the issue will be available at the workshop.
