The Web Services Interoperability Organization (WS-I) announced the general availability of the Basic Profile 1.0. The Basic Profile 1.0, which has been formally approved by the WS-I member community, consists of implementation guidelines on how core Web services specifications should be used together to develop interoperable Web services. The specifications covered by the Basic Profile include SOAP 1.1, WSDL 1.1, UDDI 2.0, XML 1.0 and XML Schema.

"Starting today, every Web service developer and provider will have a common framework for implementing interoperable solutions, and buyers will have a common reference point for purchasing decisions," said Tom Glover, chairman of WS-I. "WS-I has resolved more than 200 interoperability issues associated with using the core Web services specifications together. The Basic Profile 1.0 will significantly simplify the task of implementing interoperable Web services solutions within and across enterprise boundaries."

"Support for the Basic Profile is the baseline for interoperable Web services," said Dan Sholler, vice president of Technology Research Services at the META Group. "Customers should demand that all of their Web services- enabled technology be compliant with the Basic Profile, and that in turn will lay the foundation for Web services to fulfill their promise and provide technology independent interoperability."

Later this Fall, WS-I will release Test Tools and Sample Applications supporting the Basic Profile 1.0. The Test Tools, available in both C# and Java (TM) implementations, are designed to inspect and validate that a Web service meets the interoperability requirements of the Basic Profile. The Sample Applications demonstrate the Basic Profile at work, including the design, implementation, test and deployment of Web services, based upon selected business scenarios and implemented on 10 different platforms.

In parallel with the release of the Test Tools, WS-I will announce how Web services software vendors, hardware vendors, and services providers will be able to claim conformance of their products to the Basic Profile 1.0.

WS-I is currently developing interoperability guidelines for SOAP with Attachments, and for the Basic Security Profile. These efforts will extend the functionality provided by the Basic Profile and will reference existing specifications.

Today, more than 25 WS-I member companies announced their support for the Basic Profile. To obtain a copy of Basic Profile 1.0 and the supporting documentation, please visit WS-I's Web site at
