In scenarios where a set of independent business partners engage in complex conversations, global interaction models are a means to specify the allowed interaction behavior from a global perspective. In these models atomic interactions serve as basic building blocks and behavioral dependencies are defined between them. Global interaction models might not be locally enforceable, i.e. they specify constraints that cannot be enforced during execution without additional synchronization interactions. As this property has only been defined textually so far, this paper presents a formal definition. For doing so, this paper introduces interaction Petri nets, a Petri net extension for representing global interaction models. Algorithms for deriving the behavioral interface for each partner and for enforceability checking are provided.
