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).
This document describes an abstract feature and a concrete implementation of it for optimizing the transmission and/or wire format of SOAP messages. The concrete implementation relies on the [XML-binary Optimized Packaging] format for carrying SOAP messages.
The first part of this document (2 Abstract SOAP Transmission Optimization Feature) describes an abstract feature for optimizing the transmission and/or wire format of a SOAP message ([SOAP Version 1.2 Part 1: Messaging Framework]) by selectively encoding portions of the message, while still presenting an XML Infoset to the SOAP application.
Use of the Abstract SOAP Transmission Optimization Feature is a hop-by-hop contract between a SOAP node and the next SOAP node in the SOAP message path, providing no mandatory convention for optimization of SOAP transmission through intermediaries. The feature does provide optional means by which binding implementations MAY choose to facilitate the efficient pass-through of optimized data contained within headers or bodies relayed by an intermediary (see 2.3.4 Binding Optimizations at Intermediaries). Additional specifications might also be written to provide for other optimized multi-hop capabilities, perhaps building on the mechanisms provided herein.
The second part (3 An Optimized MIME Multipart/Related Serialization of SOAP Messages) describes an Optimized MIME Multipart/Related Serialization of SOAP Messages implementing the Abstract SOAP Transmission Optimization Feature in a binding independent way. This implementation relies on the [XML-binary Optimized Packaging] format.
The third part (4 HTTP SOAP Transmission Optimization Feature) uses this Optimized MIME Multipart/Related Serialization of SOAP Messages for describing an implementation of the Abstract Transmission Optimization Feature for the SOAP 1.2 HTTP binding (see [SOAP Version 1.2 Part 2: Adjuncts] 7. SOAP HTTP Binding).
