Microsoft, IBM and BEA Systems plan to submit their web services choreography and business process specification to standards body the Organisation for the Advancement of Structured Information Standards (Oasis) later this week.
The Business Process Execution Language for Web Services (BPEL4WS) specification was initially proposed in August 2002.
Carol Geyer, spokeswoman for Oasis, said she anticipated the submission will be in the next two to three days as the proposing companies are still making modifications to it.
According to a source, SAP and Siebel Systems are joining the original developers of BPEL4WS in the submission.
BPEL4WS is intended to provide for more automated web services, which is considered crucial to wider use of the technology for back-end integration for applications such as e-commerce.
Oasis will form a technical committee to deliberate on the specification, with an initial meeting to be held on 15 May.
The submitting companies have agreed not to seek royalties, or financial compensation, for their contributions to the specification used in any implementations.
Sun Microsystems has proposed a rival specification, Web Services Choreography Interface, which is being deliberated on by the World Wide Web Consortium.
