W3C Publishes Open Standard for Describing Web Services Policies
Policy Layer Enables Benefits of Extension Architecture
http://www.w3.org/ -- 4 September 2007 -- Today, the World Wide Web Consortium issued a critical Web standard for extending the features of Web services and Service Oriented Architecture (SOA) applications. Building on the fundamental open Web services standards from W3C, Web Services Policy enables developers to meet requirements for secure transactions, reliable messaging, addressing metadata, and other scenarios, in modular fashion. With Web Services Policy 1.5, SOA developers can enable extensions to a service without disruption or requiring changes to lower level service descriptions. The extensions themselves (consisting of what are called "policy assertions") are defined by other specifications.
Web Services Policy 1.5 Based on Industry Needs, Experience
Years of customer experience with commercial Web services applications have made clear the need for a modular approach for describing required and optional extensions used by a service. Without this capability, it can be costly to rewrite an entire service whenever application needs change. Web Services Policy 1.5 can reduce this cost. It connects the core Web services standards -- SOAP 1.2, WSDL 2.0, and XML Schema -- to a growing set of extensions that reflect industry needs and experience.
The W3C Web Services Policy Working Group invited implementers to demonstrate interoperability by evaluating software against the group's test suite. Ten implementations of Web Services Policy 1.5 helped confirm the maturity of the specification. The tests focused on security assertions, one of the most important use cases cited by industry.
Another use case, addressing metadata, is the focus of W3C's WS-Addressing Working Group. The two W3C Working Groups have collaborated to ensure that the Addressing Metadata Specification is aligned with the policy framework.
The W3C Web Services Policy Working Group also secured review from several OASIS Web Services Technical Committees (UDDI, WS-RX, WS-TX, and WS-SX) to ensure that Web Services Policy 1.5 would satisfy their use cases.

Adobe Systems, Inc.
As an active contributor and participant in the WS-Policy Working Group, Adobe is pleased to see WS-Policy become a W3C Recommendation. WS-Policy is a key component of the Web service metadata standards, allowing activities to determine compatibility and dynamically adapt to requirements at runtime. This work furthers SOA governance and management within and across enterprises, along with enabling a significant expansion in what can be done with digital rights management, web analytics, content management and messaging. WS-Policy represents a significant development in Web services and SOA, and Adobe supports the W3C in its efforts to standardise the Web.-- Charlton Barreto, Senior Computer Scientist and Software Architect, Adobe Systems Inc.
As a leading global provider of collaborative business solutions, Axway is very pleased to see WS-Policy reaching the W3C recommendation status. WS-Policy was the missing link in B2B Web Services; we now have a standard way of describing and processing policies between partners. Our Synchrony 4.1 platform will embed this essential technology.
-- Arnaud Meyniel, Web Services Product Manager, Axway Software
BEA Systems is excited by the finalization of the standardization process of W3C-Policy 1.5. A key aspect of Service Oriented Architecture deployments is the description of the services, and WS-Policy can enhance service description and can represent a crucial building block for SOA and other related initiatives such as Service Component Architecture (SCA). BEA Systems was one of the first vendors to offer supported product implementation of WS-Policy, and BEA Systems plans to continue our early adoption strategy of key interoperability initiatives.-- David Orchard, Senior Technical Director, BEA Systems
IBM is pleased to see Web Services Policy 1.5 Framework and Attachments specifications advance to Recommendation status. Customers deploying Web services based solutions with advanced quality of service characteristics (such as security) want to avoid the need for manual exchange of configuration information. The WS-Policy specifications facilitate interaction between producers and consumers of Web services within context of a Quality-of-Service policy. We supported the W3C in this effort by providing the WS-Policy Working Group co-chair, and a member of the Working Group editing team. IBM will offer support for these important standards in market leading products including WebSphere Application Server, Tivoli Federated Identity Manager and WebSphere DataPower SOA Appliances.-- Karla Norsworthy, Vice President, Software Standards, IBM
JBoss/Red Hat is pleased to see Web Services leadership continue through the W3C with the announcement of the WS-Policy standard. WS-Policy is a critical component for the evolving Web Services architecture and a standard in this area has been lacking for several years. JBoss is happy to have been associated with the working group and W3C. We are already implementing WS-Policy in our flagship Web Services product line, JBossWS.
-- Dr. Mark Little, Director of Standards, JBoss/Red Hat
As co-editors of the specifications and active participants in the workgroup, Layer 7 is very pleased to see Web Services Policy 1.5 Framework and Attachment specifications become W3C Recommendations. We see them as fundamental and necessary components for any interoperable Web Services deployment. Without a standard Policy mechanism, developers have had to resort to implementing tightly coupled, brittle systems, with hard-coded constraints and capabilities. WS-Policy will allow the deployment of truly loosely coupled Service Oriented Architectures. Layer 7 is one of the first vendors to offer a WS-Policy implementation in its products, and has been actively participating in the various interop activities to ensure successful WS-Policy interoperability.-- Dr. Toufic Boubez, Chief Technology Officer, Layer 7 Technologies
Microsoft Corporation is pleased to see Web Services Policy 1.5 become a W3C Recommendation. As co-authors and implementers of the original Web Services Policy submission in 2006, Microsoft views the Recommendation as a fundamental part of the metadata foundation for interoperable Web services. Many Web services specifications such as WS-SecurityPolicy, WS-RMPolicy, WS-AtomicTransaction, WS-Addressing Metadata and WS-MTOM Policy use WS-Policy to enable automatic and flexible use of key features such as security, reliability, transaction, addressing and message optimization. Microsoft will continue its support of Web Services Policy by implementing the W3C Recommendation in the next version of its Web services-enabled products, including the forthcoming Windows Communication Foundation 3.5.-- Andrew Layman, Partner Product Unit Manager, Microsoft Corporation
As an active participant in the WS-Policy Working Group, Nokia is pleased to see the WS-Policy Framework and Attachment specifications become W3C Recommendations. We believe it is important to have open standards for obtaining policy information associated with a service and being able to determine policy compatibility between a client and service. To give one example, policy compatibility in security is important to Web Services. WS-Policy is a major step forward and we are supportive of the W3C and its effort to drive interoperable standards for Service Oriented Architecture.-- Frederick Hirsch, Senior Architect, Nokia
