National bodies that

15、are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other internati

16、onal organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in t

17、he ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at l

18、east 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 25437 was prepared by Ecma Internati

19、onal (as ECMA-366) and was adopted, under a special “fast- track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6, Telecommunications and information exchange between systems, in parallel with its approval by national bodies of ISO and IEC. This third

20、 edition cancels and replaces the second edition (ISO/IEC 25437:2009), which has been technically revised. ISO/IEC 25437:2012(E) vi ISO/IEC 2012 All rights reservedIntroduction ISO/IEC 22534, Application Session Services, specifies XML protocols that can be used to create and manage application sess

21、ions that are independent of the transport layer protocols. This International Standard (WS-Session) specifies Web services for ISO/IEC 22534. For Service Requester to receive the event notification from the Service Provider and from web services (e.g. ECMA-348) that use this International Standard

22、for session management, this International Standard introduces WS-Eventing as the mandatory mechanism and WS-BaseNotification as an Option to manage the event channel. This International Standard uses the approach in A.2 of WS-Eventing to specify the ApplicationSessionTerminated as an operation in t

23、he Notification WSDL. Since WS-Eventing has advanced to a W3C Proposed Recommendation at W3C, the 3 rdedition of this International Standard incorporates and complies with the latest edition of WS-Eventing. Heeding the guidance in the WS-I Profiles that WS-Eventing adopted, this Standard only uses a

24、 subset of WSDL Services, in particular, this Standard does not use the WSDL 1.1 Notification and Solicit- response operations. INTERNATIONAL STANDARD ISO/IEC 25437:2012(E) ISO/IEC 2012 All rights reserved 1Information technology Telecommunications and information exchange between systems WS-Session

25、 Web services for application session services 1 Scope This International Standard specifies Web Services (in WSDL, in Clause 5) and SOAP bindings (in Clause 6) for the Application Session Services defined in ISO/IEC 22534. The Application Session Services allow Applications to create and maintain a

26、 relationship with Servers termed Application Session. The Web services specified herein, allow Service Requesters (Applications in ISO/IEC 22534) and Service Providers (Servers in ISO/IEC 22534) to create and maintain such Application Sessions. This International Standard builds upon and imports th

27、e XML schema definitions from ISO/IEC 22534. The method of making the WSDL description of the specified services available to Service Provider and Requester is out of the scope of this International Standard. The Notification WSDL specifies the ApplicationSessionTerminated operation. The operation s

28、pecifies one input message for the event notification that Service Requesters receive from the Service Provider. Service Requesters may also receive the event notifications from web services, e.g. ECMA-348, that use this International Standard for session management. 2 Conformance The Service Reques

29、ter and Service Provider conform to the Application and Server conformance specified in ISO/IEC 22534, using the WSDL definitions, SOAP bindings, and event subscription and notification specified in Clause 5, 6 and 7 respectively. The Service Provider implements and publishes the operations in the P

30、rovider WSDL in 5.1 and the Notification WSDL in 5.2. The Service Provider implements and publishes the required operations from Annex A and it may additionally implement and publish operations from Annex B. The Service Requester implements the operation in the Notification WSDL in 5.2. The Service

31、Provider supports synchronous responses to Event Subscriptions and may also implement the asynchronous response Option specified in Annex C. 3 Normative references The following referenced documents are indispensable for the application of this document.

32、applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

ISO/IEC 25437:2012(E) ISO/IEC 2012 All rights reserved 35 Abstract WSDL Definitions This Clause specifies the abstract WSDL definitions to support the services specified in ISO/IEC 22534. There are two abstract WSDL definitions and both of them are specified by the Service Provider: 1) “Pr
