OASIS TC Call for Participation: OASIS Web Services Quality Model Technical Committee

A new OASIS technical committee is being formed.
The OASIS Web Services Quality Model Technical Committee has been
proposed by the members of OASIS listed below.  The proposal (below)
meets the requirements of the OASIS TC Process [1].  The TC name,
statement of purpose, scope, list of deliverables, audience, and language
specified in the proposal will constitute the TC's official charter.
Submissions of technology for consideration by the TC, and the beginning
of technical discussions, may occur no sooner than the TC's first
meeting.

     This TC will operate under our 2005 IPR
Policy.[2]  The eligibility requirements for becoming a participant
in the TC at the first meeting (see details below) are that:

     (a) you must be an employee of an OASIS member
organization or an individual member of OASIS;

     (b) the OASIS member must sign the OASIS
membership agreement (see [3]);

     (c) you must notify the TC chair of your intent
to participate at least 15 days prior to the first meeting, which members
may do by using the "Join this TC" button on the TC's public
page at [4]; and

     (d) you must attend the first meeting of the TC,
at the time and date fixed below.

     Of course, it also will be possible to join the
TC at a later time.

     Standards always are improved by broad
participation.  Non-OASIS members who wish to participate may
contact us about joining OASIS [3].  Our rules and structure are
designed to promote inclusiveness. We look forward to assisting parties
interested in joining the community of implementers, technologists,
academics and end-users working on OASIS standardization projects. 
All also are welcome to take advantage of the public resources maintained
for each TC: a mail list archive, document repository and public comments
facility, which will be available via the TC's public home page at
[4].  Archives of the TC's mail list and public comment lists, as
with all OASIS TCs, will be visible at [5].

     Please feel free to forward this announcement to
any other appropriate lists.  OASIS is an open standards
organization; we encourage your feedback. JBC

WEB SERVICES QUALITY MODEL TC

a. Name

OASIS Web Services Quality Model (WSQM) Technical Committee.

b. Statement of purpose

With the widespread proliferation of Web services into software
integration and service integration, the quality of Web services will
become a very significant factor in executing the services successfully
among service consumers, providers, brokers, managers, etc. 
Although most Web services systems adhere to standards, they may exhibit
a wide range of quality in such aspects as interoperability, security,
and manageability, etc. It is possible that a specific level of quality
of Web services could be requested and agreed according to a contract
between a provider and a consumer. However, there is no known common
specific model or criteria to evaluate the quality level of 
services. So, we need an obvious quality model of Web services that may
be composed of three components: quality factors, quality associates, and
quality activity. 

Each quality factor measure may specify classification and criteria for
Web services quality.  Each quality factor is a fundamental
component that recognizes Web services quality as the target for control,
such as manageability, security, interoperability, stability, etc. 
Measures of quality associates may define or constrain the role and
responsibility of persons/organizations with a relationship to a service,
in detail. Quality activity may provide a model for all the actions
needed to specify, agree upon and obtain a specific level of services
such as contracting, monitoring, and notifying.  By specifying the
quality model, service consumers could significantly reduce the risks
associated with obtaining practical and stable Web services. 

The TC will prepare a quality model (WSQM) in the context of contracting
for Web services between associates conceptually, in order to secure Web
services at a specific level of service quality. Probably as a second
phase after the general model is described, the TC also will propose
WS-QDL (Web Services Quality Description Language) to describe the WSQM
in a standardized type of XML representation. Additionally, the TC will
develop test guidelines for our quality model.

c. Scope

We would like to specify an overall model of quality of Web services in
WSQM TC. It will include specified quality factors, associate roles, and
activities. It will not cover the detailed  management of Web
services which has already been covered in WSDM. 

First, we will prepare the Quality model in the focus of contract for Web
services between associates more conceptually in order to secure Web
services Quality at some level. Then we will propose WS-QDL (Web Services
Quality Description Language) to describe the WSQM in the type of XML
schema. Additionally, if possible, we develop the test guideline for our
quality model. So, we will first make a Web Services Quality Model (WSQM)
1.0 and Web Services Quality Test Model (WSQTM) 1.0.  We anticipate
the contribution of a Web Services Quality Model and Test Guideline,
already developed and applied practically in the public arena of Korean
e-government projects in 2004 to serve as a starting point. We will
develop a global standard model for Web services quality by attaching and
expanding various relationship of associates and contracts case by
case.  The TC will be open to anybody with interest in this topic
and global cooperation.

d. Deliverables

1. Web Services Quality Model (WSQM): Completion date in twelve months
from formation of this TC. 

2. Schema for describing WS-QDL: Completion date is six months after the
completion of the WSQM above. 

3. Web Services Quality Test Guideline: Completion date is twelve months
after the completion of WS-QDL.

e. IPR Mode 

RF on Limited Terms (as specified in the OASIS IPR Policy)

f. Anticipated audience

All Web Service and SOA TCs, standards groups and vendors, eGovernment
personnel and users are the primary audience. The work should be of
interest to anyone involved with Web Services regardless of the standards
body under which the work is sanctioned.

g. Language

The TC will conduct its business in English.  The TC may elect to
form subcommittees that produce localized documentation of the TC's work
in additional languages.

==== 

The following additional information relates to the launch of the TC, but
will not be part of the TC's charter.

a. Similar and related work and liaisons

All Web services groups are the primary targets of this Model. Liaisons
will be decided by team consensus based on needs.  It is anticipated
that liaisons will be needed for many or all Web Services-related
Technical Committees and may be necessary or useful for the following
organizations (Note: this is a non-exhaustive list):

OASIS WSDM TC 

OASIS WSN TC 

OASIS WSRF TC 

OASIS DCML TCs 

OASIS FWSI TC 

OASIS SOA Reference Model TC 

OASIS WSRM TC 

OASIS WS-RX TC 

OASIS WSS TC 

OASIS ebSOA TC 

OASIS ebXML IIC TC

OASIS UDDI Specification TC 

OASIS WSBPEL TC 

OASIS WS-CAF TC

W3C WS Choreography Working Group 

W3C WS Description Working Group 

W3C XML Protocol Working Group

Many other works may be relevant, including network management models
from DMTF, GGF and ITU, and interoperability profiles from 
WS-I.
