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.
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.
Web Services Quality Model (WSQM): Completion date in twelve months from formation of this TC.
Schema for describing WS-QDL: Completion date is six months after the completion of the WSQM above.
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.
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):
d. On-going meeting schedule (subject to TC approval).
Meeting schedule will be monthly conference calls as well as quarterly Face to Face meetings pending approval and adoption by the TC. If necessary, sponsors will be solicited from among participants
