Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that 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 international 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 the 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 least 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 International (as ECMA-366) and was adopted, under a special “fast-
track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its
approval by national bodies of ISO and IEC.

Introduction
(ECMA 354) ISO/IEC 22534 specifies XML protocols that can be used to create and manage application
sessions that are independent of the transport layer protocols. This International Standard (WS-Session)
specifies Web services for ECMA-354 (ISO/IEC 22534).

INTERNATIONAL STANDARD ISO/IEC 25437:2006(E)

Information technology — Telecommunications and information
exchange between systems — WS-Session — Web Services for
Application Session Services
1 Scope
This International Standard specifies Web Services (in WSDL) and a SOAP binding for the Application
Session Services defined in (ECMA 354) ISO/IEC 22534. The Application Session Services allow Applications
to create and maintain a relationship with Servers termed Application Session. The Web services specified
herein, allow Service Subscribers (Applications in (ECMA 354) ISO/IEC 22534) and Service Providers
(Servers in (ECMA 354) ISO/IEC 22534) to create and maintain such Application Sessions.
This International Standard builds upon and imports the XML schema definitions from (ECMA 354)
ISO/IEC 22534.
Although this International Standard only specifies the abstract WSDL definitions and its SOAP binding,
Annex A shows an example WSDL binding with SOAP/HTTP.
Annex B lists SOAP XML Templates for (ECMA 354) ISO/IEC 22534 Messages.
Annex C illustrates how WS-Eventing can be used to establish event channels to receive
ApplicationSessionTerminated messages.
2 Conformance
Conforming implementations support the port type and the WSDL to SOAP binding as specified in this
International Standard.
To support the port type, conforming implementations support all operations in the port type.
For each operation, conforming implementations also satisfy all the requirements that (ECMA 354)
ISO/IEC 22534 specifies for the corresponding service definition.
3 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

4 Terms and definitions
For the purposes of this document, the terms and definitions given in (ECMA 354) ISO/IEC 22534 apply.
This International Standard refers to these two main Web services concepts:
1) Service Subscriber – provides the following major functions: 1) queries a Service Provider for
services, and 2) binds and interacts with a Service Provider.
2) Service Provider – provides the following major functions: 1) publishes its services (e.g. WSDL
document), and 2) interacts with a Service Subscriber.
4.1 Namespaces
This International Standard uses these two Ecma namespaces:
1) aps: http://www.ecma-international.org/standards/ecma-354/appl_session: This International Standard
imports all XML messages defined in ECMA-354 from the aps namespace.
2) tns: http://www.ecma-international.org/standards/ecma-366/ws-session: The target namespace for this
International Standard.
This International Standard refers to these other namespaces:
1) http://schemas.xmlsoap.org/wsdl/: This contains the W3C WSDL 1.1 schema.
2) http://www.w3.org/2001/XMLSchema: This contains the W3C XML Schema definition.
3) http://schemas.xmlsoap.org/wsdl/soap: This contains the W3C SOAP bindings for WSDL 1.1.
5 Service Provider WSDL Abstract Definitions
This Clause specifies the abstract WSDL definitions to support the services specified in (ECMA 354)
ISO/IEC 22534.

6 Service Provider WSDL SOAP Binding
This Clause specifies the binding of the abstract WSDL definitions in Clause 5 with SOAP Messages.
ECMA-354 (ISO/IEC 22534) requires Applications to include the aps:sessionID in some service requests, in
these cases, the corresponding Service Subscribers shall include the aps:sessionID as a header block in the
application SOAP message.
