The World Wide Web Consortium's WS-Addressing working group Friday released three working drafts, moving the specification closer to ratification.
The spec outlines a standard way for referencing and addressing network endpoints receiving Web services messages.
The drafts were identified as deliverables when the group was chartered in October.
In August, Microsoft, Sun Microsystems Inc., IBM, BEA Systems Inc. and SAP AG submitted the spec to the W3C, an early sign of cooperation between Microsoft and Sun on a Web services specification.
"It's a nuts-and-bolts spec. By itself, it doesn't enable an application to be built, but it allows other things to be built on top of it," said Ronald Schmelzer, founder and senior analyst of ZapThink LLC. "It will help developers name endpoints and indicate how a Web service can reach them."
The working group charter demanded that the submission document be separated into three specifications: WS-Addressing Core, SOAP Binding and WSDL Binding.
WS-Addressing Core removes a dependency on the WS-Policy specification and references to WS-Trust and WS-Security specs that existed earlier. The new spec explains abstract properties and an XML information set that identifies Web services endpoints.
WS-Addressing WSDL Binding, meanwhile, shows how the WS-Addressing Core abstract properties are described using the Web Services Description Language.
WS-Addressing SOAP Binding defines how the abstract properties are bound to SOAP messages. These bindings map a Web service endpoint reference to the message, the document said.
