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 Canadian Advisory Committee (CAC) 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).
This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
This Recommendation | International Standard specifies the messages and encodings that enable the use of Fast Web Services, together with the means of description of such services.
The protocol used to support these services satisfies the requirements of the SOAP processing model (see W3C SOAP Part 1, clause 2) and is based on the transfer of:
a) ASN.1 SOAP messages that contain embedded ASN.1 encoded values and embedded fast infoset documents; and
b) fast infoset SOAP messages.
This Recommendation | International Standard also specifies:
- an ASN.1 module for ASN.1 SOAP that defines the Envelope type (a value of this type corresponds to an ASN.1 SOAP message);
- a conceptual mapping between ASN.1 SOAP messages and W3C SOAP messages (defined as an instance of the XML Infoset, see W3C SOAP Part 1, clause 5);
- an extension to the W3C SOAP processing model for the processing of embedded ASN.1 encoded values;
- the ASN.1 SOAP HTTP Binding, which is a modification and extension of the W3C SOAP HTTP Binding (see W3C SOAP Part 2, clause 7), for the transfer of ASN.1 SOAP messages;
- support for the transfer of W3C SOAP message infosets serialized as fast infoset documents (fast infoset SOAP messages) using the W3C SOAP HTTP Binding (see W3C SOAP Part 2, clause 7);
- SOAP-oriented service descriptions that define the interface to and the semantics of Fast Web Services.
Two Multipurpose Internet Mail Extensions (MIME) media type names are allocated to identify:
- ASN.1 SOAP messages encoded using Basic Aligned PER;
- fast infoset SOAP messages.
