Web services standard: how it works

Oracle hopes to avert a battle over rival efforts to create Web services standards by asking the leading oversight group to pick a winner.

Oracle's proposal could help ease tensions between Sun and the tandem of Microsoft and IBM. Sun has been embroiled in a bitter feud with Microsoft and IBM over Web service standards, including a year-long dispute over Sun's desire to join a Web services coalition that Microsoft and IBM created to promote the technology.

Sun executives, over the past several months, have been the most vocal in publicly expressing concern that IBM and Microsoft have the ability to charge "tolls" to developers - in the form of royalties on patents - for using the Web services specifications they jointly have created, such as Simple Object Access Protocol (SOAP) and Web Services Description Language (WSDL). Neither Microsoft nor IBM has formally stated a desire to charge royalties on the standards, which are in part based on patents held by them.

Sun, for example, first balked at supporting a Web services security specification, called WS-Security, until its three creators - Microsoft, IBM and VeriSign - agreed to make the technology royalty-free.

Oracle executives said they expect that the W3C's Web Services Architecture Working Group will vote on Thursday on its proposal to create a committee to take the handful of existing choreography specifications and create a unified standard.

In addition to Sun, IBM and Microsoft, others are working on their own choreography standards including the Organization for the Advancement of Structured Information Standards, or OASIS, and the Business Process Management Initiative.

Microsoft could not be reached for comment. An IBM representative said the company will take part in the W3C talks. "We will be participating in the discussions about this proposed working group to sort out what needs to be done and when," said the IBM representative, who said the company supports BPEL4WS.

Members of the W3C Web Services Architecture Working Group include Microsoft, Apple, BEA, Macromedia, Nokia, AT&T, Hewlett-Packard, Cisco Systems and VeriSign.

Oracle's Deutsch, who said his company is neutral on which technology wins out, said he expects the W3C will support Oracle's idea to create a common choreography standard. The W3C previously accepted IBM and Microsoft's SOAP and WSDL and turned them into standards.

"We're cautiously optimistic," he said. "There are several different proposals. We will consider everything available and come up with a consensus specification."
