Electronic Communications of the EASST Volume 73 (2016) Graph Computation Models Selected Revised Papers from GCM 2015 Preface 2 pages Guest Editors: Detlef Plump Managing Editors: Tiziana Margaria, Julia Padberg, Gabriele Taentzer ECEASST Home Page: http://www.easst.org/eceasst/ ISSN 1863-2122 http://www.easst.org/eceasst/ ECEASST Preface The Sixth International Workshop on Graph Computation Models (GCM 2015) took place in L’Aquila, Italy, on 20 July 2015, as part of STAF 2015 (Software Technologies: Applications and Foundations). This volume of the Electronic Communications of the EASST contains six revised and extended articles which have been selected from the proceedings of GCM 2015. In addition, there is an invited paper by Anthony Anjorin, Erhan Leblebici and Andy Schürr. All submitted contributions were carefully reviewed by the GCM Programme Committee and addi- tional reviewers. The topics of the papers include triple graph grammars, applications of graph transformation to parsing and policy modelling, parallel execution models of graph transforma- tion, the theoretical foundations of graph transformation with attributes, and the verification of graph programs. I would like to thank the authors for revising and extending their workshop papers, and the reviewers for their contribution in ensuring the high quality of this volume. Thanks are also due to Gabi Taentzer and the ECEASST staff for their help in preparing this volume.
