Subject: 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

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 SOA Reference Model TC
OASIS UDDI Specification 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.

b. Anticipated contributions

- The Web Services Quality Model
- The Guidelines for Web Services Quality Testing
