Call for Papers Second International Workshop on Graph Transformation and Visual Modeling Techniques <http://www.elet.polimi.it/GT-VMT> Crete, Greece, July 12 and 13, 2001 A Satellite Event of ICALP'2001 <http://www.cti.gr/engl_v/news/sc_conf/icalp.html> SCOPE AND OBJECTIVES OF THE WORKSHOP The growing success of visual modeling techniques in the design and development of complex applications is justified by many reasons. For example, the use of visual representations simplifies the communication both among developers and between developers and their customers; furthermore, visual techniques provide a high-level, yet precise language which allows to express and reason about concepts at their natural level of abstraction; finally, the availability of modern computational resources (like graphical workstations) provides easier access to tools supporting such techniques. However, despite the wide-spread usage of visual modeling techniques, compared to textual languages there is a lack of well-understood (and integrated) methodologies for defining their semantics. For example, there exists no equivalent approach to operational semantics in the SOS style, nor is there a general method for defining denotational semantics. The same applies to concepts like type systems, deductive proof methods, etc. for visual modeling techniques. On the other hand there are a number of individual approaches which exploit formalisms like Graph Transformation Systems, Process Algebra, Abstract State Machines, etc. to solve certain aspects of the overall problem. The workshop aims at bringing together scientists and researchers interested in discussing formal methodologies for the definition of syntax and semantics of visual modeling techniques. In particular contributions exploring the use of the theory of Graph Grammars and Graph Transformation Systems to this aim are welcome, as well as approaches based on other formalisms. Preferably, the contributions should be methodological in nature, rather than focusing on particular technical aspects. 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 modeling 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 modeling techniques. Position papers and contributions making methodological statements are strongly encouraged. Submissions should be sent preferably in postscript format to the address baresi@elet.polimi.it (Luciano Baresi) before the submission deadline. In the case electronic submission is not possible, three copies should be sent to the address: Luciano Baresi DEI - Politecnico di Milano Piazza L. da Vinci, 32. I-20133 - MILANO (Italy) IMPORTANT DATES Deadline for submissions: March 5, 2001 Notification of acceptance: April 5, 2001 Final version of accepted extended abstracts: May 2, 2001 PROGRAM COMMITTEE Luciano Baresi (Politecnico di Milano, Italy) [co-chair] Andrea Corradini (University of Pisa, Italy) Gregor Engels (University of Paderborn, Germany) Robert France (Colorado State University, USA) Reiko Heckel (University of Paderborn, Germany) Hans-Joerg Kreowski (University of Bremen, Germany) Francesco Parisi Presicce (Universit=E0 di Roma, Italy) Mauro Pezze' (Universita' di Milano, Bicocca, Italy)[co-chair] Gregor Rozenberg (Universiteit Leiden ,Netherlands) Gabriele Taentzer (TU Berlin, Germany) [co-chair] PROCEEDINGS The abstracts of the contributions accepted for presentation will be published in a volume collecting the contributions to all satellite workshops of ICALP 2001. 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.
