Industry Leaders Demonstrate Interoperability of WS-Policy Using the UDDI Policy Attachment
Friday 27 April 2007The interoperability evaluation event for the World Wide Web Consortium's (W3C) included Web Services Policy 1.5 Framework and Attachment (WS-Policy) Candidate Recommendation specifications.
webMethods, Inc, a business integration and optimization software company, today announced successful demonstration of interoperability of the WS-Policy Candidate Recommendation specifications using the UDDI (Universal Description, Discovery and Integration) 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.
""We're delighted by the opportunity to have hosted this important event," said Prasad Yendluri, principal architect, Office of the CTO, webMethods, Inc. "UDDI-based registries are fundamental to policy-based SOA governance. By ensuring that policies can be attached to UDDI entities in a manner that is compliant with the WS-Policy specification, we're able to greatly enhance the interoperability of all of the components used to achieve policy-based governance."

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 (Web Services Definition Language) 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.
""We have been very active in WS-Policy since our inception," said Toufic Boubez, Chief Technology Officer, Layer 7 Technologies. "The ability to exchange interoperable policies between enforcement points like our SecureSpan appliance and UDDI registries gives our customers a powerful standards-based solution for overall SOA management and governance."
