OASIS WSBPEL TC

OASIS TC Call For Participation: WSBPEL

Date:      Thu, 17 Apr 2003 00:12:32 -0400
From:      Karl Best <karl.best@oasis-open.org>
To:        members@lists.oasis-open.org, tc-announce@lists.oasis-open.org,
           xml-dev@lists.xml.org, wsbpel@lists.oasis-open.org
Subject:   OASIS TC Call For Participation: WSBPEL

A new OASIS technical committee is being formed. The OASIS Web Services Business Process Execution Language Technical Committee (WSBPEL TC) has been proposed by the members of OASIS listed below.

The proposal for a new TC 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.

As specified by the OASIS TC Process, the requirements for becoming a member of the TC are that you must 1) be an employee of an OASIS member organization or an Individual member of OASIS; 2) notify the TC chair of your intent to participate at least 15 days prior to the first meeting; and 3) attend the first meeting of the TC.

For OASIS members, to sign up for the TC using the new OASIS collaborative tools, go to the TC's public page at http://www.oasis-open.org/committees/wsbpel and click on the button for "Join This TC" at the top of the page. You may add yourself to the roster of the TC either as a Prospective Member (if you intend to become a member of the TC) or an Observer. A notice will automatically be sent to the TC chair, which fulfills requirement #2 above. You must sign up for membership at least 15 days before the first meeting and must attend the first meeting of the TC in order to become a member.

Note that membership in OASIS TCs is by individual, and not by organization.

For non-OASIS members, a public comment list wsbpel-comment@lists.oasis-open.org is available for the public to make comments on the work of this TC; the public may subscribe to this list by going to the mail list web page at http://lists.oasis-open.org/ob/adm.pl.

The archives of the TC's private and comment mail lists are visible to the public at http://lists.oasis-open.org/archives/.

Proposal for Oasis Web Services Business Process Execution Language Technical Committee

Name of the TC

OASIS Web Services Business Process Execution Language (BPEL)

Statement of Purpose

The purpose of the Web Services Business Process Execution Language TC is to continue work on the business process language published in the Business Process Execution Language for Web Services (BPEL4WS) specification in August 2002 [1]. Continuing the approach and design used in BPEL4WS, the work of the BPEL TC will focus on specifying the common concepts for a business process execution language which form the necessary technical foundation for multiple usage patterns including both the process interface descriptions required for business protocols and executable process models. It is explicitly not a goal of the TC to specify bindings to specific hardware/software platforms and other mechanisms required for a complete runtime environment for process implementation.

The Technical Committee will take advantage of the OASIS provided services for such things as e-mail lists and archives, and also web pages for tracking progress. E-mail archives will be visible to the public.

Identification of Existing Activities

Many efforts related to business process management and related technologies are underway throughout the industry. The following work may be relevant to this Business Process Execution Language TC:

Technical Committee Deliverables

The TC has the following deliverables:

  • The specification of the core elements and functionalities of BPEL4WS
  • An extension specification for business protocol description
  • An extension specification for executable process description

The two extension specifications for the usage patterns of business protocol description and executable process description are normative, mandatory extensions to the core specification and will include only the essential feature extensions required for the given usage pattern.

The scope of the Web Services Business Process Execution Language Technical Committee is the support of process mechanisms in the following areas:

a. Sequencing of process activities, especially Web service interactions
b. Correlation of messages and process instances
c. Recovery behavior in case of failures and exceptional conditions
d. Bilateral Web service based relationships between process roles

Specification work in areas not explicitly listed in the scope above is out-of-scope for this TC but will be considered for future TC charters layered on the results of this TC. It is the intent of the proposers that the TC address requested clarifications to this charter; seeking to resolve ambiguities and narrowing the scope of work. Other requested charter changes that are not clarifications may be noted and archived for possible future work after the conclusion of this TC's lifecycle. Each of the process mechanisms will use implementation and language neutral XML formats defined in XML Schema [2].

The OASIS Web Services Business Process Execution Language TC will:

  1. Accept contributions as input within the TC's defined scope. BEA, IBM, Microsoft, SAP and Siebel intend to submit the Business Process Execution Language for Web Services (BPEL4WS) V1.1 specification [3] at the first meeting of the TC. This BPEL4WS document is an update to the BPEL4WS specification published by IBM, Microsoft, and BEA on August 9th 2002. The revised document is a modularized and updated version of the original specification that clearly identifies the core concepts and required extensions for BPEL4WS.

  2. Produce as output a specification, in one or more documents, for the "Web Services Business Process Execution Language", hereafter referred to as the "resultant specification". This resultant specification will reflect refinements and corrections that are identified by the TC members within the scope of the TC charter. In the interests of stability, continuity and speed, the committee will not make arbitrary changes, i.e., scope will be limited to material technologic improvements. At the TC's option, suggestions for future features, out-of-scope extensions, harmonization with other or broader work and the like may be noted and archived for possible future work after the conclusion of this TC's lifecycle. The final draft of the resultant specification will be due within 9 months of the first meeting.

  3. Identify relevant Web services efforts to assist in leveraging the resultant specification as a part of their specifications or solutions.

  4. Establish appropriate relationships and coordinate with the chairs of the other business process related standards organizations and industry groups as appropriate, and in accordance with the OASIS Bylaws and TC Process.

  5. Oversee ongoing maintenance and errata of the resultant specification.

Language in Which the TC will Conduct Business
