Karl,
Please forward this W3C CfR to the BTP TC, requesting them to provide a
response to OASIS management within 2 weeks. I would like to see a listing
of and specific portions of the BTP Specification that cover work items,
deliverables or other specific topics noted within the WSC WG Scope of Work.
As a W3C member, I plan to file a response on behalf of OASIS.
Upon initial review of this CfR (and without benefit of closer examination),
I am disturbed by the lack of research that the organizers of this new WSC
WG have done on other relevant work. Their is NO mention of the OASIS BTP
TC work and no listing of a liaison to OASIS to coordinate their proposed
new work with relevant work that has gone on at OASIS over the past 22
months in the BTP TC.
Thanks,
Patrick Gannon
President & CEO

Subject: Call for Review: Web Services Choreography Working Group
Proposal
Dear Advisory Committee representative,
This is a call for review of a proposal to modify the Web Services
Activity and create a Web Services Choreography Working Group as part
of the existing Web Services Activity.
The charter of the proposed Working Group can be found at:
http://www.w3.org/2002/11/chor-proposal
If you have any questions or need further information, please contact
Hugo Haas, Web Services Activity Lead at <hugo@w3.org>, or
C. M. Sperberg-McQueen, Architecture Domain Leader at <cmsmcq@w3.org>.
Thank you,
for Tim Berners-Lee, W3C Director;
Hugo Haas, W3C Web Services Activity Lead and
Susan Lesch, for the W3C Communications Team
----------------
Activity Summary
----------------
The Web Services Activity statement is:
http://www.w3.org/2002/ws/Activity
As described there, new work in the Web Services Activity is to
be started on the basis of work by the Web Services Architecture
Working Group.
A Web Services Choreography Working Group is proposed to address the
following problem:
| Existing specifications for Web services describe the indivisible
| units of atomic interactions. It has become clear that taking the
| next step in the development of Web services will require the
| ability to compose and describe the relationships between atomic
| services. Although differing terminology is used in the industry,
| such as orchestration, collaboration, coordination, conversations,
| etc., the terms all share a common characteristic of describing
| linkages and usage patterns between Web services. For the purpose
| of this document, and without prejudice, we use the term
| choreography as a label to denote this space.
|
| [..]
|
| The Web Services Choreography Working Group, part of the Web Services
| Activity, is chartered to create the definition of a choreography,
| language(s) for describing a choreography, as well as the rules for
| composition of, and interaction among, such choreographed Web
| services. The language(s) should build upon the foundation of the Web
| Service Description Language 1.2 (WSDL 1.2).
-- Proposal for Web Services Choreography Working Group Charter
http://www.w3.org/2002/11/chor-proposal#scope
In order to guarantee the broadest possible grounding for the work of
the Working Group, the first face-to-face meeting is proposed to be in
the form of an open forum with presentations to the Working Group of
relevant technologies listed in the charter.
----------------------
Context and Motivation
----------------------
The Web Services Architecture Working Group has considered
choreography since the group's inception. Discussion grew as various
proposals were published and considered:
- In February 2002, W3C received the WSCL Submission
(http://www.w3.org/Submission/2002/02/) from Hewlett-Packard
Company, drawing attention to the choreography area.
- In June 2002, W3C received the WSCI Submission
(http://www.w3.org/Submission/2002/04/) from BEA Systems, BPMI.org,
Commerce One, Fujitsu Limited, Intalio, IONA, Oracle Corporation,
SAP AG, SeeBeyond Technology Corporation and Sun Microsystems,
asking the creation of a Web Services Choreography Working Group.
In response, the W3C Team asked the Web Services Architecture Working
Group to review the Submission.
At the beginning of August 2002, another set of proposals (BPEL4WS,
WS-Coordination, WS-Transaction) was released by BEA Systems, IBM and
Microsoft.
At the Working Group's 11-13 September 2002 face-to-face meeting, the
Working Group agreed unanimously that, due to the proliferation of
proposals, work on choreography should happen soon in a open
environment:
| The WSA WG is committed to the creation an open common Web Services
| architecture where customers, developers, and IT vendors build
| solutions together--an architecture that takes the principles of
| interoperability, vendor-independence, and openness into account.
|
| It has become clear that a critical next step in the evolution of
| Web services will be the ability to compose and describe the
| relationships between Web services to support stateful,
| long-running interactions. Although differing terminology is used in
| the industry, such as orchestration, collaboration, coordination,
| conversations, etc., the terms all share a common characteristic of
| describing linkages and usage patterns between web services. For
| this purpose, and without prejudice, we use the term choreography.
|
| The WSA WG encourages the formation of an open, industry-wide
| working group with the aim of developing interoperable and open Web
| services standard(s) that support stateful, long-running
| interactions.
-- Web Services Architecture Working Group: 11-13 September 2002
face-to-face minutes
http://www.w3.org/2002/ws/arch/2/09/f2f-minutes
After further consideration, the Working Group decided (17 to 1
in favor, with 8 abstentions) to request the formal chartering of
a Working Group on choreography specifically at W3C.
The Web Services Architecture Working Group expressed the motivation
for such work:
| WSDL has proved very useful for describing a single service.
| Currently complex natural language describing the obligations of the
| participants detailing how to use a service (sequencing, state
| management, etc.) have to accompany a WSDL description. The next step
| is to partially replace these somewhat imprecise instructions with
| precise language. This will simplify the daunting task companies now
| face when trying to use web services to integrate their business
| processes. In a B2B context such a specification could reduce the
| cost of integrating with new trading partners and responding to
| changes in existing interfaces. As well, creating a standard language
| to describe the relationships between document exchanges will be
| helpful to other standards bodies, such as RosettaNet or CIDX, giving
| them a standard infrastructure for message choreography and enabling
| them to focus on the core competencies relevant to their domain.
-- Proposal for Web Services Choreography Working Group Charter
http://www.w3.org/2002/11/chor-proposal#scope
The W3C Director recognizes the importance of this work for Web
services and is therefore presenting this charter for your
consideration.
It is believed that the Web Services Architecture Working Group has
framed the work enough for experts in this area to continue the
discussion inside this new proposed W3C Working Group.
The Web Services Architecture Working Group identified BPEL4WS and
WSCI as important inputs for the proposed work. As per the request
from the Web Services Architecture Working Group and the Web Services
Coordination Group, the W3C Management Team has been approaching the
main stakeholders in this area to try and guarantee their
participation in this effort. While WSCI was submitted to W3C, the
authors of BPEL4WS have not made the specification available to W3C to
work on yet.
--------------------------------
Activity Structure and Resources
--------------------------------
W3C will allocate 0.6 full-time equivalent engineers to the Working
Group. Yves Lafon will be the W3C Team Contact for this Working Group.
Hugo Haas will be the Alternate Team Contact.
The W3C Team is in the process of evaluating candidates for chairing
the Web Services Choreography Working Group. Proposals for additional
candidates are welcome, and should be sent to Michael Sperberg-McQueen
<cmsmcq@w3.org>, Yves Lafon <ylafon@w3.org> and Hugo Haas
<hugo@w3.org>.
---------------------
Intellectual Property
---------------------
As with all Working Groups under the Web Services Activity, the
proposed Web Services Choreography Working Group will operate in a
Royalty-Free mode, as defined in the W3C Current Patent Practice:
http://www.w3.org/TR/2002/NOTE-patent-practice-20020124
-----------------------------------------
Proposed Changes to Web Services Activity
-----------------------------------------
This proposal to modify the Web Services Activity
Web Services Activity
http://www.w3.org/2002/ws/
to include a Web Services Choreography Working Group follows the
guidelines of sections 3.3 and 4.2.1 of the W3C Process Document:
3.3 Activity Proposals
http://www.w3.org/Consortium/Process-20010719/activities.html#BPCreation
4.2.1 Working Group and Interest Group Creation and Modification
http://www.w3.org/Consortium/Process-20010719/groups#WGCreation
----------------------------
Review Form and Instructions
----------------------------
This call for review includes a call for participation. Should the
final version of the charter be significantly different as a result of
this review, the W3C Team will treat the participation commitments as
provisional.
In the discussions about how to proceed with this work, some Members
suggested that further preparatory work should be done before
chartering the Working Group. In the response form below, this
possibility has been called out separately: in addition to supporting
the idea or being opposed to it, you can express the view that W3C
should definitely work in this area, but that the work should be
started only in a few months, after some additional preparation work
that you can specify.
1. Preparation. Please review the proposed charter:
http://www.w3.org/2002/11/chor-proposal
2. Deadline. Your review must be received before:
24:00 UTC 12 December 2002
The Director expects to announce the results of the review within two
weeks after the deadline. The Director will keep the Advisory Committee
informed if additional time for consideration is required.
3. Where to send your review.
Replies to this proposal must be sent to:
team-ws-chor-review@w3.org
The W3C Team encourages Advisory Committee representatives to send
their reply both to the review list <team-ws-chor-review@w3.org>,
which is Team-confidential, and to the AC forum <w3c-ac-forum@w3.org>,
which is Member-readable, in order to foster discussions around this
proposal.
