CFP: OASIS Web Services Reliable Messaging Technical Committee

CFP: OASIS Web Services Reliable Messaging Technical Committee

Date:      Thu, 13 Feb 2003 08:32:35 -0500
From:      Karl Best <>
Subject:   OASIS TC Call for Participation: WSRM TC (Reliable Messaging)

A new OASIS technical committee is being formed. The OASIS Web Services Reliable Messaging Technical Committee (WS-RM TC) has been proposed by the following members of OASIS: Doug Bunting, Sun Microsystems; David Burdett, Commerce One; David Chappell, Sonic Software; Colleen Evans, Sonic Software; Kazunori Iwasa, Fujitsu; Sunil Kunisetty, Oracle; Jeff Mischkinsky, Oracle; Katsutoshi Nihei, NEC; Eisaku Nishiyama, Hitachi; Sanjay Patil, IONA; Tom Rutt, Fujitsu; Alan J. Weissberger, NEC; Pete Wenzel, See Beyond; Scott Werden, WRQ; Nobuyuki Yamamoto, Hitachi; Prasad Yendluri, webMethods; and Sinisa Zimek, SAP.

The proposal for a new TC meets the requirements of the OASIS TC Process (see, and is appended to this message. The proposal, which includes a statement of purpose, list of deliverables, and proposed schedule, will constitute the TC's charter. The TC Process allows these items to be clarified (revised) by the TC members; such clarifications (revisions), as well as submissions of technology for consideration by the TC and the beginning of technical discussions, may occur no sooner than the TC's first meeting.

To become a member of this new TC you must 1) be an employee of an OASIS member organization or an Individual member of OASIS; 2) notify the TC chair, Tom Rutt ( of your intent to participate at least 15 days prior to the first meeting; and 3) attend the first meeting on 26 March 2003. You should also subscribe to the TC's mail list. Note that membership in OASIS TCs is by individual, and not by organization. You must be eligible for participation at the time you time you notify the chair.

The private mail list is for committee discussions. TC members as well as any other interested OASIS members should subscribe to the list by going to the mail list web page at, or by sending a message to with the word "subscribe" as the body of the message. (Note that subscribing to the mail list does not make you a member of the TC; to become a member you must contact the TC chair and attend the first meeting as described in the preceeding paragraph.)

A public comment list will be available for the public to make comments on the work of this TC; a message may be sent to the TC via the address

The archives of both of these mail lists are visible to the public at

Web Services Reliable Messaging Technical Committee (WS-RM TC)


The name of this Technical Committee is the Web Services Reliable Messaging (WS-RM) Technical Committee (TC).


The purpose of this TC is to create a generic and open model for ensuring reliable message delivery for Web services.

This TC defines reliable message delivery as the ability to guarantee message delivery to software applications -- Web services or Web service client applications -- with a chosen level of quality of service (QoS).

For this TC effort, QoS will be defined as the ability to determine the following aspects of message delivery:

  • Message persistence
  • Message acknowledgement and resending
  • Elimination of duplicate messages
  • Ordered delivery of messages
  • Delivery status awareness for sender and receiver applications

The TC will specify rules for combining these features and their parameters.

Essential elements of web services are SOAP and WSDL. The specification to be created will provide WSDL definitions for reliable messaging and the message formats will be specified as SOAP headers and/or body content. The resulting specification must be programming language-neutral and platform-neutral.

Lastly, the TC will address the dependencies between the capacity of the messaging nodes (persistence, message processing) and the level of QoS that can be provided.

The TC will focus on end-to-end reliable messaging. The TC will initially define reliable messaging requirements for Web services at the SOAP protocol level but can specify reliable messaging solutions that can be used with other messaging protocols.

Interoperability, ease of implementation, and ease of use will be fundamental characteristics for WS-RM. The TC's work should build upon similar, existing standards wherever possible and permitted and align with other relevant standards. Alignment means any of the following: feature reuse, bindings, guidelines on how to jointly use the specification with other related ones, or addressing requirements from other related standards.

Composability is a critical aspect of Web Service specifications. The resulting specification must be non-overlapping with, and have demonstrated composability with other Web Service specifications that are being developed in open, recognized standards setting organizations. The WS-RM TC will collaborate with other relevant OASIS TCs, such as the ebXML Message Service and the WS-Security TCs, as appropriate. The WS-RM TC will also work to align with relevant efforts of other organizations, such as the W3C's Web Service Architecture Working Group.

The WS-RM TC will accept as input the WS-Reliability specification [1] published by Fujitsu, Hitachi, Oracle, NEC, Sonic Software and Sun Microsystems on January 9, 2003. Other contributions in addition to WS-Reliability will be accepted for consideration without any prejudice or restrictions, and evaluated on their technical merit, as long as the contributions conform to this charter.

The benefits and results of this work will be:

  • The establishment of a standard and interoperable way of achieving a known, acceptable, and defined level of reliability at the SOAP messaging level.

  • The establishment of a common vocabulary for describing reliable message exchange patterns.

Out Of Scope

The following features are outside the WS-RM TC's scope:

  • Synchronous RPC at the application level
  • Conversations
  • Routing
  • Security: However, other mechanisms, such as work from the Web Services Security TC at OASIS, should be able to be used along with an implementation of this specification
  • Encryption
  • Message Integrity: However, WS-RM's work should be able to be used with Digital Signatures to provide some level of message integrity
  • Authentication
  • Message Non-Repudiation
  • Mechanisms for transaction and service references

As appropriate, this TC will use policy frameworks that are developed in open, recognized standards setting organizations and that meet the requirements of this TC for specifying quality of service levels.

In no event shall this Technical Committee finalize or approve any technical specification if it believes that the use, distribution, or implementation of such specification would necessarily require the unauthorized infringement of any third party rights known to the Technical Committee, and such third party has not agreed to provide necessary license rights on perpetual, royalty-free, non-discriminatory terms.


Reliability requirements document, such as use cases for WS-RM in EAI, B2B and wireless scenarios. Due within 2 months of first meeting.

WS-Reliability specification, including description of WS-Reliability bindings to transport protocol(s). This specification will reflect refinements and changes made to the submitted version of WS-Reliability that are identified by the WS-RM TC members for additional functionality and semantic clarity within the scope of the TC charter. Final draft due within 6 months of first meeting.

At the appropriate time the TC shall submit its Committee Specifications for balloting by OASIS membership for OASIS Standard status.


All business will be conducted in English.


The first meeting of the WS-RM TC will take place on Wednesday, 3/26, 2003, from 14:30 to 16:30 PST, over the phone, at a number to be provided to prospective participants no later than 5 days before the meeting. That date and time will be the time of record for establishing initial voting membership under the OASIS TC process. After the initial teleconference meeting, the TC shall meet bi-weekly over the phone unless another schedule is agreed upon. For example, phone meetings will not be necessary during face to face meetings.

A face to face meeting of the TC in the San Francisco area of the U.S. shall be arranged at the first phone meeting, to take place no later than three months after this initial phone meeting. Subsequent face to face meetings will be quarterly.

TC Co-Sponsors

The following persons eligible to participate in OASIS technical committees state that they are committed to the purpose and schedule stated above:


The TC shall be chaired by Tom Rutt, Fujitsu Software Corp.

Meeting Sponsors

The sponsor for face-to-face meetings during the first year shall be Oracle. The sponsor for phone meetings during the first year shall be Fujitsu.
