"We recast SOAP 1.2 in terms of the infoset," Fallside said. An infoset is an information description of an XML document, he said. "The infoset description does not care about a specific system but about a general model being conveyed in an XML document."
"I think this is a good step for the industry," said Ronald Schmelzer, an analyst with ZapThink LLC. "What the release of the proposed recommendation for SOAP shows is two major things: the final step in a long process towards industry consensus around Web Services specifications, and the fact that theyve resolved quite a few interoperability issues. While the WS-I [Web Services Interoperability Organization] was mainly slated with resolving interoperability issues between different Web services implementations, solving these issues in the specification definition process is the best route to go—the more ambiguities that are removed from the spec early on in the process, the better it will be for companies building products for the spec, and for enterprises implementing them."
Members of the XML Protocol working group include AT&T Co., BEA Systems Inc., IBM Corp., IONA Technologies Inc., Microsoft Corp., Oracle Corp., SAP AG, Sun Microsystems Inc., Systinet Inc., TIBCO Software Inc. and Unisys Corp., among others.
Cambridge, Mass.-based Systinet said its WASP [Web Applications and Services Platform] for Java, 4.5 is a reference implementation for the standard, and was used to provide valuable evidence of interoperable implementations of SOAP 1.2.
Fallside said SOAP 1.3 will be coming down the road. "In general, working groups, once they have completed a recommendation, they spend some time on errata and other things," he said. "To date no decision has been made on SOAP 1.3."
