The Web Services Interoperability Organization (WS-I) has published draft documents on web services and security with an emphasis on service oriented architecture (SOA), seeking public feedback.

SOA architects have been waiting for these deliverables, which provide guidance on interoperability for core web services and business processes in enterprises, WS-I said.

"The web services specifications and the web services stack is the underlying technology for SOA," said Michael Bechauf, WS-I chairman and SAP vice president of industry standards.

Formed in 2002, WS-I focuses on helping vendors and users implement web services. "At the end of the day, the end user really shouldn't care about the underlying specifications," Bechauf said.

WS-I features members such as IBM, Microsoft, Oracle, SAP, and Sun Microsystems.

Working Group Drafts being published include Basic Profile 1.2, Basic Security Profile 1.1, and Reliable Secure Profile 1.0 Usage Scenarios. The draft documents are up for public and member review and are expected to be approved early in 2007.

"The tangible results will be that vendors will actually build solutions according to those profiles," with users assured that the systems will work together, Bechauf said.

Basic Profile 1.2 is the revision of the Basic Profile 1.1, which offers guidance on basic interoperability of the web services stack. Version 1.2 incorporates errata and includes requirements pertaining to serialisation of web services envelopes and their representation in messages from the WS-I Simple SOAP Binding Profile 1.0.
