External Reviewers

This volume contains the papers presented at CompoNet 2012: second international workshop on Petri nets Compositions (and other models of concurrency) held on June 26th 2012 in Hamburg, Germany as a part of the International Conference on Applications and Theory of Petri Nets (PETRI NETS 2012). This workshop aims at offering to researchers, using or developing compositions within their specific Petri net variants or related models of concurrency, a forum promoting cross-discussion and cross-fertilisation with the hope to enable the emergence of novel models of Petri nets compositions, dedicated to various application domains. We would like to thank the authors of submitted papers for their interest in CompoNet. We also thank the program committee members and the external reviewers for their efficient work during the reviewing process. Last but not least, we thank the authors of the EasyChair conference management system which made the practical organisation of the reviewing process considerably easier.
