6、GE HANDLING SERVICES: ELECTRONIC DATA INTERCHANGE MESSAGING SERVICE Summary This Recommendation is one of a set of Recommendations for message handling. The entire set provides a comprehensive specification for message handling comprising any number of cooperating open-systems. Message handling syst

7、ems and services enable users to exchange messages on a store-and-forward basis. A message submitted by one user, the originator, is conveyed by the message transfer system (MTS), the principal component of a larger message handling system (MHS), and is subsequently delivered to one or more addition

8、al users, the messages recipients. An MHS comprises a variety of interconnected functional entities. Message transfer agents (MTAs) cooperate to perform the store-and-forward message transfer function. Message stores (MSs) provide storage for messages and enable their submission, retrieval and manag

9、ement. User agents (UAs) help users access MHS. Access units (AUs) provide links to other communication systems and services of various kinds (e.g. other telematic services, postal services). This Recommendation defines the overall system and service description of the message handling application c

10、alled EDI messaging. This edition introduces new Elements of Services (EOS) to provide the EDI message store with capabilities similar to those of the IPM message store for message store correlation and services. Source ITU-T Recommendation F.435 was revised by ITU-T Study Group 7 (1997-2000) and wa

11、s approved under the WTSC Resolution No. 1 procedure on 18 June 1999. ii Recommendation F.435 (06/99) FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni-cations. The ITU Telecommunication Standardization Sector (ITU-T) is a perma

12、nent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years

13、, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall w

14、ithin ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGH

15、TS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserte

16、d by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned

17、 that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2000 All rights reserved.

Definitions of the elements of service applicable to EDI messaging are contained in Annex B. The elements of service applicable to t

44、he Message Transfer Service, and used by EDI messaging, are called out in this Recommendation, however their definitions are contained in Annex B/F.400/X.400. 3.1 EDI forwarding Onward transfer of a received EDIM to one or more recipients determined by the forwarding EDI user agent/message store. ED

45、I forwarding takes place when an EDI message having been delivered to an EDI user agent or EDI message store is forwarded onward to another EDI user agent or EDI message store. 3.2 EDI message Information in electronic form that is transferred between EDI messaging users. An EDI message is a member

46、of the primary class of information objects conveyed between EDI messaging users. See also clause 5 of ITU-T Rec. X.435 | ISO/IEC 10021-9. 3.3 EDI messaging user User that engages in EDI messaging. An EDI messaging user originates, receives, or both originates and receives EDI messages. The EDI mess

47、aging environment contains any number of EDI messaging users. An EDI messaging user may be a person or a computer process. An EDI messaging user may access the EDI messaging system through an access unit. 3.4 EDI notification Member of the secondary class of information objects that indicates to the

48、 originator of an EDI message the disposition of EDIM responsibility for the EDI message. 3.5 EDI message responsibility EDI message responsibility indicates whether the subject EDI message has been made available to a specific user by its EDI user agent/message store. EDI message responsibility car
