Submissions may be theoretical or practical papers, as well as case studies, addressing composition as a central topic either for Petri nets or related models of concurrency. The scope includes in particular (but not only):

• definitions and properties of composable, compositional hierarchical or modular variants of Petri nets
• improving modelling using compositions
• improving analysis using compositions or decompositions
• compositional or modular Petri nets semantics of other formalisms
• implementation issues related to compositions
• comparison of composition techniques
• comparison of Petri nets variants supporting compositions
• tools supporting compositions of Petri nets
• case studies involving compositions as a crucial feature

Papers may be accepted as full publication, for presentation only or for posters. It is possible to submit an extended abstract to apply for a presentation only or a poster.

A printed version of the proceedings will be distributed at the workshop and on-line proceedings will be published via CEUR-WS. After the PETRI NETS conference, best workshop papers will be invited to a joint post-proceedings, to be published in the new subseries of Lecture Notes in Computer Science (LNCS) entitled Transactions on Petri Nets and Other Models of Concurrency (ToPNoC), i.e., a selection of papers from all workshops will be combined into a single volume. The revised papers will go through an additional round of reviewing.

A printed version of the extended abstracts and posters will be distributed at the workshop and a bibliographical note will appear in the proceeding.

Papers must contain original contributions, be self-contained and clearly written in English, and include appropriate references to and comparison with related work. Simultaneous submission to other conferences or workshops with proceedings is not allowed.
