Initial WS-I Working Group Planning Sessions

WS-I Announces Formation of Key Working Groups; Membership Grows to More Than 100

100+ Member Community Meets for Initial Working Group Planning Sessions

AT&T, Proctor & Gamble, Sabre and Others Join Industry Effort

San Francisco, CA, USA. April 18, 2002.

The Web Services Interoperability Organization ("WS-I") ( announced the formation of key working groups at the organization's first community meeting held this week in San Francisco. WS-I is an open industry organization committed to promoting consistent and reliable interoperability among Web services across platforms, applications and programming languages. More than 100 companies have joined WS-I since its official launch in February 2002.

"The enormous interest we've received from such a broad base of industry leaders demonstrates the importance of WS-I's mission and the emphasis companies are placing on Web services interoperability," said Anthony Roby, WS-I board member and working group chair. "WS-I has aligned around a common definition of Web services based on open industry standards and is now focused on delivering the tools and implementation guidance necessary for creating interoperable Web services."

Working Group Charters Defined

WS-I has defined the charters for three initial working groups:

  • The Basic Web Services Profile Working Group will identify a core set of specifications (including XML Schema, SOAP, WSDL and UDDI) that provide the foundation for Web services, and will establish conventions and recommendations for coordinating their use.

  • The Sample Applications Working Group will provide sample applications of basic Web services to accelerate deployments. These sample applications illustrate best practices for implementation and will be developed in multiple programming languages using multiple development tools. Sample applications serve as working examples for companies planning to implement Web services.

  • The Test Materials and Tools Development Working Group will develop a suite of self-administered tests to verify conformance with the Basic Web Services Profile. These tools and materials can be used to ensure that Web services interoperate across platforms, applications and programming languages.

WS-I is targeting a Fall release for the first set of working group deliverables.

Strong Industry Interest

"Web services will play an increasingly important role for Procter & Gamble as underlying standards and architecture mature, thus allowing us to improve the interoperability of our enterprise-wide legacy and Web applications," said Steve David, chief information officer at Proctor & Gamble, a new WS-I community member. "WS-I represents a common industry vision for Web services interoperability and ensures the continued evolution of Web services technologies."
