CSA Preface
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 40210” throughout.
At the time of publication, ISO/IEC 40210:2011 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.
Abstract
SOAP Version 1.2 is a lightweight protocol intended for exchanging structured information in a decentralized, distributed environment. Part 1: Messaging Framework defines, using XML technologies, an extensible messaging framework containing a message construct that can be exchanged over a variety of underlying protocols.
Introduction
SOAP Version 1.2 (SOAP) is a lightweight protocol intended for exchanging structured information in a decentralized, distributed environment. It uses XML technologies to define an extensible messaging framework providing a message construct that can be exchanged over a variety of underlying protocols. The framework has been designed to be independent of any particular programming model and other implementation specific semantics.
Two major design goals for SOAP are simplicity and extensibility (see XMLP Requirements [XMLP Requirements]). SOAP attempts to meet these goals by omitting, from the messaging framework, features that are often found in distributed systems. Such features include but are not limited to reliability, security, correlation, routing, and Message Exchange Patterns (MEPs). While it is anticipated that many features will be defined, this specification provides specifics only for two MEPs. Other features are left to be defined as extensions by other specifications.
The SOAP Version 1.2 specification consists of three parts. Part 1 of the SOAP Version 1.2 specification (this document) defines the SOAP messaging framework consisting of:
1.The SOAP processing model defining the rules for processing a SOAP message (see 2. SOAP Processing Model).
2.The SOAP Extensibility model defining the concepts of SOAP features and SOAP modules (see 3. SOAP Extensibility Model).
3.The SOAP underlying protocol binding framework describing the rules for defining a binding to an underlying protocol that can be used for exchanging SOAP messages between SOAP nodes (see 4. SOAP Protocol Binding Framework).
4.The SOAP message construct defining the structure of a SOAP message (see 5. SOAP Message Construct).
The SOAP 1.2 Primer [SOAP Part 0] is a non-normative document intended to provide an easily understandable tutorial on the features of the SOAP Version 1.2 specifications.
SOAP 1.2 Part 2 [SOAP Part 2] describes a set of adjuncts that can be used in connection with the SOAP messaging framework.
Note:
In previous versions of this specification the SOAP name was an acronym. This is no longer the case.
