Content-based Publish/Subscribe (CPS) is a powerful paradigm providing loosely-coupled, event-driven messaging services. Although the general CPS model is well-known, many features remain implementation specic because of dierent application requirements. Many of these requirements can be captured in policies that separate service semantics from system mechanisms, but no such policy framework currently exists in the CPS context. In this paper, we propose a novel policy model and framework for CPS systems that benets from the scalability and expressiveness of existing CPS matching algorithms. In particular, we provide a reference implementation and several evaluation scenarios that demonstrate how our approach easily and dynamically enables features such as notication semantics, meta-events, security zoning, and CPS rewalls.
