Abstract

WS-Policy is a framework that can be used to describe as- sertions for web services message exchange. In the context of Service Oriented Architectures and Clouds, where web services are belonging to, machine-to-machine communication is one of its core ideas. When those machines try to apply WS-Policy, mainly two events can occur: First, the machine-exchanged policies have common assertions – there is an intersection. Second, there is no direct intersection and the participants must reach an agreement by minimal adjustments to the policies. This paper introduces a new approach for reaching intersection by computing adjustments to the policies using partial ordering.
