The World Wide Web Consortium (W3C) has released the proposed recommendation for the Soap 1.2 specification, saying that the protocol is cleaned up and in a strong position for final review.
The group called the latest version of the XML protocol for exchanging structured information in a decentralised environment, such as the web, lightweight and flexible.
"We have reached a very stable state and we hope the specification will be implemented," said Carine Bournez, a member of the W3C XML protocol working group.
More than 400 issues have been resolved, including 150 from Soap 1.1 and the protocol has now been sent on to the W3C membership for final review, which closes 7 June.
Soap 1.2 consists of the Soap 1.2 Messaging Framework, Soap 1.2 Adjuncts and a Primer. The Messaging Framework provides a message construct, a processing model and an extensibility framework, whereas the Adjuncts defines a set of adjuncts such as rules for encoding Soap messages.
Additionally, the cleaned-up protocol integrates core XML technologies and works with W3C XML schemas.
Bournez said the messaging part of the protocol is the most important, adding that the Soap developers committee gave a lot of feedback on the issue, with a focus placed on interoperability.
The protocol has gone through several working drafts and reviews, and the W3C now believes that it is ready for widespread adoption.
The organisations that are members of the consortium now have a month to give their final stamp of approval.
