Industry Leaders Demonstrate Interoperability of WS-Policy Using the UDDI Policy Attachment

webMethods, Inc. recently announced successful demonstration of interoperability of the WS-Policy Candidate Recommendation specifications using the UDDI standard. The first-ever interoperability evaluation event for the World Wide Web Consortium's (W3C) Web Services Policy 1.5 Framework and Attachment (WS-Policy) Candidate Recommendation specifications was hosted by webMethods. During this recently concluded event, leading products that support the UDDI registry specification for lifecycle governance -- the HP SOA Systinet Standard Edition and the webMethods Infravio X-Registry -- were used to demonstrate interoperability with the Layer 7 SecureSpan XML Appliance, a widely deployed policy enforcement point, using the WS-Policy specifications.

The development of a standards-based model for governance interoperability between Policy Enforcement Points (PEP) and each policy's system-of-record represents a significant step towards enabling standards-based federated policy management for the enterprise. 

One of the fundamental challenges that service-oriented architecture (SOA) works to address is orchestrating a series of very dynamic interactions between disparate Web services in accordance with enterprise-class standards for Quality-of-Service. WS-Policy helps to achieve this objective by facilitating agreement between producers and consumers of Web services. More specifically, WS-Policy provides a means for describing and communicating the capabilities and requirements of specific Web services in a coherent and reliable manner, ensuring that specific preconditions are fully met within each interaction.
As an underlying component of WS-Policy, the "Web Services Policy 1.5 - Attachment" specification can be used to bind specific policies to unique services via either WSDL or UDDI. In the case of a UDDI registry, it defines how policies can be stored and accessed within an associated repository to deliver optimal performance. Successful testing paves the way for UDDI to be included, along with WSDL, as an acceptable means for policy exchange in the Candidate Recommendation of the specification.
