Abstract: We address cross-organizational workflows, such as document workflows, which consist of multiple workflow modules each of which can interact with others by sending and receiving messages. Our goal is to guarantee that the global workflow network has properties such as termination while merely requiring properties that can be checked locally in individual modules. The resulting query nets are based on predicate/transition Petri nets and implement formal constructs for business rules, thereby ensuring such global termination. Our method does not require the notion of a global specification, as employed by Kindler, Martens and Reisig.
