News Release: WS-Addressing 1.0 is a W3C Recommendation

Web Services applications developers got a critical tool today in the  
form of W3C standards for addressing Web Services messages - WS- 
Addressing 1.0 Core, and its SOAP binding.  For more information,  
please contact Janet Daly, W3C, at +1 617 253 5884 <janet@w3.org> or

http://www.w3.org/ -- 9 May 2006 -- The World Wide Web Consortium  
(W3C) announced today that Web Services Addressing 1.0 - consisting  
of the Core specification and the SOAP Binding - is a W3C  
Recommendation. Industry now has a reliable, proven interoperable  
standard to address Web services messages.

"Web Services Addressing 1.0 provides a mechanism to developers on  
how to address objects for Web services applications," explained  
Philippe Le Hégaret, W3C Architecture Domain Leader. "It extends the  
capabilities of Web services by enabling asynchronous message  
exchanges, and allowing more than two services to interact."

Web Services Addressing 1.0 Defines New Standard Way to Address Web  
Services Objects

Web Services Addressing 1.0 provides a transport-neutral mechanism  
for addressing objects in Web services applications built on top of  
URIs. This new method is called an endpoint reference, or EPR. EPRs  
are designed to solve the issues posed by specific scenarios:

     * Dynamic generation and customization of service endpoint  
descriptions, such as those created for a session id or customer id
     * Referencing and description of specific service instances that  
are created as the result of stateful interactions
     * Flexible and dynamic exchange of endpoint information in  
tightly coupled environments where communicating parties share a set  
of common assumptions about specific policies or protocols that are  
used during the interaction.

In addition to the addressing function of EPRs, they can serve a role  
similar to that of a cookie for Web services interactions. Another  
special feature of EPRs is referred to as a metadata bag. The  
metadata bag allows for additional information - whether it be a  
policy statement, a WSDL description, or Semantic Web data - to be  
included with the EPR.

EPRs serve as a key component of Web services specifications  
developed in a variety of different standards and industry  
organizations. The W3C work ensures that these diverse groups have a  
universal starting point with regards to addressing Web services  
messages.

SOAP Binding for WS Addressing Makes New, More Powerful Applications  
Easier to Implement, More Secure

Along with the core specification, the W3C Web Services Addressing  
Working Group issued an accompanying Recommendation, "Web Services  
Addressing 1.0 - SOAP Binding". The SOAP binding provides  
instructions to developers interested in implementing Web Services  
Addressing with either the W3C standard SOAP 1.2 or the earlier SOAP  
1.1 version. It specifies security considerations to use Web Services  
Addressing safely.

Web Services Addressing 1.0 Facilitates Asynchronous Interactions

Web Services Addressing introduces a way to specify the destination  
address, reply messages and faults in SOAP messages, taking advantage  
of SOAP's versatility in being carried by arbitrary underlying  
protocols and being applicable to a wide variety of interaction  
patterns. This capability facilitates in particular scenarios with  
long-running requests.

Web Services Addressing Carries Significant Industry Participation  
and Endorsement

The participants in the Web Services Addressing Working Group include  
BEA Systems, BT, CA, Ericsson, Fujitsu Limited, Hitachi Ltd, HP, IBM,  
IONA Technologies Inc., JBoss Inc., Microsoft Corporation, Nortel  
Networks, Oracle Corporation, Ricoh Company Ltd., SAP AG, Sonic  
Software, Sonoa Systems Inc., Sun Microsystems Inc., Systinet Inc.,  
TIBCO Software Inc., webMethods Inc, and WSO2. Many of these  
participants have implemented or are planning to implement Web  
Services Addressing 1.0 in their products, as identified in the  
testimonials.


Testimonials from CA, Hitachi and Microsoft

By enabling asynchronous messaging and better coordination of data  
exchanges, WS-Addressing frees Web services from the classic HTTP  
request/response and brings a new level of flexibility to corporate  
SOA environments. CA will continue to contribute to these  
advancements in SOA standards to help our customers better leverage  
all available information resources across and beyond the enterprise.

Hitachi is pleased that the W3C's new Recommendation "WS-Addressing"  
has standardized general methods of addressing Web services  
endpoints. Many business processes and practical applications require  
transport-independent addressing mechanisms. WS-Addressing permits  
for the first time a normative approach, which is a significant  
milestone that encourages the widespread use of Web services. The  
flexibility provided by this standard allows these Web service  
mechanisms to be used in a far wider scope of system images.
-- Takao Nakamura, Executive General Manager, Software Division,  
Hitachi, Ltd.


Microsoft Corp. is pleased to see WS-Addressing 1.0 become a W3C  
Recommendation. As co-authors and implementers of the original WS- 
Addressing submission in 2004, Microsoft has long viewed having a  
standard method of addressing messages as a fundamental extension to  
SOAP. Many other specifications, such as WS-Trust, WS- 
ReliableMessaging, and WS-Coordination, leverage this facility to  
provide secure, reliable, transacted Web services that interoperate  
across platforms. Microsoft will continue its support of WS- 
Addressing by implementing the W3C Recommendation in the next  
versions of its Web services-enabled products, including the  
forthcoming Windows Communication Foundation 1.0
