Abstract

In service-oriented architectures (SOA), deadlock-free interactionof services is an important correctness criterion. To support servicediscovery in an SOA, operating guidelines serve as a structure to characterizeall deadlock-freely interacting partners of a services. In practice,however, there are intended and unintended deadlock-freely interactingpartners of a service. In this paper, we provide a formal approach to expressintended and unintended behavior as behavioral constraints. Withsuch a constraint, unintended partners can be "filtered" yielding a customizedoperating guideline. Customized operating guidelines can be appliedto validate a service and for service discovery.
