CAN/CSA-ISO/IEC 40270:18 (R2022)
Information Technology — W3C Web Services Policy 1.5 — Framework (Adopted ISO/IEC 40270:2011, first edition, 2011-09-01)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
For brevity, this Standard will be referred to as “CAN/CSA-ISO/IEC 40270” throughout.
At the time of publication, ISO/IEC 40270:2011 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
This Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. From time to time, ISO/IEC may publish addenda, corrigenda, etc. The TCIT will review these documents for approval and publication. For a listing, refer to the Current Standards Activities page at standardsactivities.csa.ca.
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
The Web Services Policy 1.5 - Framework provides a general purpose model and corresponding syntax to describe the policies of entities in a Web services-based system. Web Services Policy Framework defines a base set of constructs that can be used and extended by other Web services specifications to describe a broad range of service requirements and capabilities.
Web Services Policy 1.5 - Framework defines a framework and a model for expressing policies that refer to domain-specific capabilities, requirements, and general characteristics of entities in a Web services-based system.
Web Services Policy 1.5 - Framework does not cover discovery of policy, policy scopes and subjects, or their respective attachment mechanisms. A policy attachment is a mechanism for associating policy with one or more policy scopes. A policy scope is a collection of policy subjects to which a policy applies. A policy subject is an entity (e.g., an endpoint, message, resource, interaction) with which a policy can be associated. Web Services Policy 1.5 - Attachment [Web Services Policy Attachment] defines such policy attachment mechanisms, especially for associating policy with arbitrary XML elements [XML 1.0], WSDL artifacts [WSDL 1.1, WSDL 2.0 Core Language], and UDDI elements [UDDI API 2.0, UDDI Data Structure 2.0, UDDI 3.0]. Other specifications are free to define either extensions to the mechanisms defined in Web Services Policy 1.5 - Attachment [Web Services Policy Attachment], or additional mechanisms not covered by Web Services Policy 1.5 - Attachment [Web Services Policy Attachment], for purposes of associating policy with policy scopes and subjects.
