Subject: (ANN) AS4 Profile of ebMS 3.0 Version 1.0 approved and published as a Committee Specification

OASIS Members,

We are pleased to announce the approval and publication of an OASIS
Committee Specification (CS) by the members of the OASIS ebXML
Messaging Services TC:

AS4 Profile of ebMS 3.0 Version 1.0
Committee Specification 02
13 August 2011


While ebMS 3.0 represents a leap forward in reducing the complexity of
Web Services B2B messaging, the specification still contains numerous
options and comprehensive alternatives for addressing a variety of
scenarios for exchanging data over a Web Services platform. The AS4
profile of the ebMS 3.0 specification has been developed in order to
bring continuity to the principles and simplicity that made AS2
successful, while adding better compliance to Web Services standards,
and features such as message pulling capability and a built-in Receipt
mechanism. Using ebMS 3.0 as a base, a subset of functionality is
defined along with implementation guidelines adopted based on the
“just-enough” design principles and
AS2 functional requirements to trim down ebMS 3.0 into a more
simplified and AS2-like specification for Web Services B2B messaging.

This document defines the AS4 profile as a combination of a
conformance profile that concerns an implementation capability, and of
a usage profile that concerns how to use this implementation. A couple
of variants are defined for the AS4 conformance profile - the AS4
ebHandler profile and the AS4 Light Client profile -  that reflect
different endpoint capabilities.

Members of the OASIS ebXML Messaging Services TC [1] requested a
Special Majority Vote to approve this specification as a Committee
Specification. The specification had been released for public review
as required by the TC Process [2]. The vote to approve at Committee
Specification (CS) level passed [3], and the approved CS <stage> is
now available online in the OASIS Library as referenced above.

Our congratulations to the TC on achieving this milestone.
