TC PROPOSAL
OASIS WEB SERVICES QUALITY MODEL TC
a. The name of the TC, such name not to have been previously used for an OASIS TC and not to include any trademarks or service marks not owned by OASIS.The proposed TC name is subject to TC Administrator approval and may not include any misleading or inappropriate names. The proposed name must specify any acronyms or abbreviations of the name that shall be used to refer to the TC.
OASIS Web Services Quality Model (WSQM) Technical Committee.
b. A statement of purpose, including a definition of the problem to be solved.
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. EachQuality factor measures 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 asmanageability, 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 the difficulties in 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. The scope of the work of the TC, which must be germane to the mission of OASIS, and which includes a definition of what is and what is not the work of the TC, and how it can be determined when the work of the TC has been completed. The scope may reference a specific contribution of existing work as a starting point, but other contributions may be made by TC members on or after the first meeting of the TC. Such other contributions will be considered by the voting members of the TC on an equal basis to improve the original starting point contribution.
We would like to specify an overall model of quality of Web services in WSQMTC.It will includespecified quality factors, associate roles, and activities. It does not cover the detail 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.
We alsodevelop test guidelines for our quality model.
We anticipate the contribution of a Web services Quality Model and Test Guideline,already developed and applied practically in the public arena of Korea e-government projects in 2004to serve as a starting point.
We will develop a global standard model for Web Services quality by attaching and expanding various relationships of associates and contracts case by case.
The TC will be open to anybody with interest this topic and global cooperation.
d. A list of deliverables, with completion dates.
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 WSQM.
e. Specification of the IPR Mode under which the TC will operate.
RF on Limited Terms (as specified in the OASIS IPR Policy)
f. The anticipated audience or users of the work.
All Web Service and SOA TCs, standards groups and vendors, e-Government 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. The language in which the TC will conduct business.
English. The TC may elect to form subcommittees that produce localized documentation of the TC's work in additional languages.
------
The following is informational only for the purposes of starting the TC, and will not be part of the TC's charter.
a. Identification of similar or applicable work that is being done in other OASIS TCs or by other organizations, why there is a need for another effort in this area and how this proposed TC will be different, and what level of liaison will be pursued with these other organizations.
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 TC
