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, aiso take part in the work. In the field of information technology, ISO and IEc have established a joint technical committee, ISO/IEC JTC 1. 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. International Standard ISO/lEC 10026-5 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 21, Open systems interconnection,data management and open distributed processing. ISO/lEC 10026 consists of the following parts, under the general title Information technology - Open Systems Interconnection Distributed Transaction Processing: Part 1:OSI TP Model Part 2: OSI TP Service Part3:Protocolspecification Part4: Protocol Implementation Conformance Statement (PiCS) Part 5: Application context proforma and guidelines when using OSITP Part6:UnstructuredData Transfer Part 7: Message queueing Annex A forms an integral part of this part of iSO/lEC 10026.
