[sorry for multiple copies] ---------------- FIRST CALL FOR CONTRIBUTIONS ----------------- Workshop on Graph Transformation and Visual Modeling Techniques <http://www.di.unipi.it/GT-VMT/> Geneva, Switzerland Saturday July 15, 2000 A Satellite Event of ICALP'2000 <http://cui.unige.ch/~icalp/> -------------------------------------------------------------------- SCOPE AND OBJECTIVES OF THE WORKSHOP Visual modelling techniques provide an intuitive, yet precise way in order to express and reason about concepts at their natural level of abstraction. The success of visual techniques in computer science and engineering resulted in a variety of methods and notations addressing different application domains and different phases of the development process. Diagrammatic languages are used, for example, during requirement specification in order to support the communication between developers and customers; but also for describing the architecture of systems and as high-level visual programming languages. However, despite the wide-spread usage of visual modelling techniques there is a lack of well-understood (and integrated) methodologies for defining their syntax and semantics. Until now, there exists no equivalent to Backus-Naur-Form which would be the notation for defining the syntax of a visual language. The same applies to type systems, deductive proof methods, operational or denotational semantics for visual modelling techniques. In fact, the situation could be compared with the state-of-the-art in programming languages about thirty years ago when the definition and implementation of languages was an ad-hoc task, and formal semantics was an exception rather than the rule. The workshop aims at bringing together scientists and researchers interested in discussing formal methodologies for the definition of syntax and semantics of visual modelling techniques. All aspects of this problem are of potential interest ranging from the concrete syntax defined, for example, by Constraint Grammars or Picture Layout Grammars, the abstract syntax specified by means of Meta Modelling or Graph Grammars, and the semantics of visual modelling techniques given, e.g., in terms of Graph Transformation, Process Algebra, Abstract State Machines, Type Theory, Logic, etc. In particular, we believe that Graph Grammars and Graph Transformation may play a central role in the definition of visual modelling techniques because they provide the graphical analogous to Chomsky Grammars and Term Rewriting which are widely used for defining the syntax and semantics of textual languages. CALL FOR CONTRIBUTIONS Authors are invited to submit extended abstracts of up to 5 (five) A4 pages. The contributions should report about ongoing research in the area of graph transformation and visual modelling techniques, especially on the syntax and semantics of visual languages according to the scope and objectives of the workshop. Contributions exploring the use of Graph Grammars and Graph Transformation Systems are particularly welcome, as well as papers which cover several aspects or integrate different formalisms for the definition of visual modelling techniques. Position papers and contributions making methodological statements are strongly encouraged. Submissions should be sent preferably in postscript format to the address <andrea@di.unipi.it> (Andrea Corradini) before the submission deadline. In the case electronic submission is not possible, three copies should be sent to the address: Andrea Corradini Dipartimento di Informatica Corso Italia 40 56125 - Pisa - ITALY IMPORTANT DATES Deadline for submissions: March 1, 2000 Notification of acceptance: April 3, 2000 Final version of accepted extended abstracts: April 28, 2000 PROGRAM COMMITTEE Andrea Corradini (University of Pisa, I) [co-chair] Hartmut Ehrig (Technical University Berlin, D) Wolfgang Emmerich (University College London, GB) Reiko Heckel (University of Paderborn, D) [co-chair] Dirk Janssens (University of Antwerp, B) Hans-Joerg Kreowski (University of Bremen, D) Fernando Orejas (University of Catalonia, Barcelona, E) Grzegorz Rozenberg (University of Leiden, NL) Andy Schuerr (University of the German Federal Armed Forces, Munich, D) PROCEEDINGS The abstracts of the contributions accepted for presentation will be published in a volume collecting the contributions to all satellite workshops of ICALP 2000. The volume will be published by Carleton Scientific, and it will be distributed to all ICALP participants. On the basis of the number and quality of the submissions, the Program Committee will consider the possibility of inviting submissions for a special issue of an international journal dedicated to the workshop.
