Foreword
ISO (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the specialized system for worldwide
standardization. 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, also take part in the work.
International Standards are drafted in accordance with the rules given in the
ISO/IEC Directives, Part 3.
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.
Attention is drawn to the possibility that some of the elements of this part of
ISO/IEC 10021 may be the subject of patent rights. ISO and IEC shall not be held
responsible for identifying any or all such patent rights.
International Standard ISO/IEC 10021-8 was prepared by Joint Technical
Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6,
Telecommunications and information exchange between systems, in collaboration
with ITU-T.
This second edition cancels and replaces the first edition (ISO/IEC 10021-8:1995),
which has been technically revised.

ISO/IEC 10021-8 : 1999 (E)
Introduction
This part of ISO/IEC 10021 is one of a number of parts of ISO/IEC 10021
(Information technology - Message Handling Systems (MHS)).
Message handling systems and services enables user to exchange of 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 other users, the message's recipients. A user may interact directly with the
MTS, or indirectly via a message store (MS).
The MTS comprises a variety of interconnected functional entities called
message transfer agents (MTAs). MTAs cooperate to transfer messages and deliver
them to their intended recipients. Message stores (MSs) provide storage for
messages and enable their submission, retrieval and management. 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 part of ISO/IEC 10021 was initially developed and published by the ITU-T in
1991. The current ITU-T version is published as ITU-T Recommendation F.435
(1999).
This part of ISO/IEC 10021 defines the overall system and service description of
the message handling application called EDI Messaging.
ISO/IEC NOTE
As stated in the ITU-T version of this part of ISO/IEC 10021 [i.e., F.435 (1999)],
the expression “Administration” is used for conciseness to indicate both a
telecommunication Administration and recognized private operating agency.

3.1 Terms defined in this part of ISO/IEC 10021
3.1.1 EDI forwarding: Onward transfer of a received EDIM to one or more recipients determined by the
forwarding EDI user agent/message store.
EDI 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.
3.1.2 EDI message: Information in electronic form that is transferred between EDI messaging users. An EDI
message is a member of the primary class of information objects conveyed between EDI messaging users.
See also ISO/IEC 10021-9 | ITU-T Recommendation X.435 clause 8.
3.1.3 EDI messaging user: User that engages in EDI messaging. An EDI messaging user originates, receives, or
both originates and receives EDI messages. The EDI messaging 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.
3.1.4 EDI notification: Member of the secondary class of information objects that indicates to the originator of an
EDI message the disposition of EDIM responsibility for the EDI message.
3.1.5 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 carries no legal
significance within this part of ISO/IEC 10021 and ISO/IEC 10021-9 | ITU-T Recommendation X.435.

6 EDI messaging service
6.1 Introduction
The EDI messaging service provides an EDI messaging user with features to assist in communicating with other EDI
messaging users. EDI messaging users are in many cases computer processes. The EDI messaging service uses the
capabilities of the Message Transfer service (see also Recommendation F.410) for sending and receiving EDI
messages. The elements of service describing the features of the EDI messaging service are defined in annex B, and
classified in clause 14.
EDI, electronic data interchange, can be described as computer to computer exchange of structured business data, such
as invoices and purchase orders. In some cases the EDI messaging service can be used to transmit an EDI interchange
to a physical rendition system, such as a physical delivery system, or facsimile.
The EDI messaging service is provided by EDI messaging.
6.2 EDI messaging
EDI messaging (EDIMG) consists of the exchange of EDI messages (EDIMs), and EDI notifications (EDINs), which
are information objects specified in ISO/IEC 10021-9 | ITU-T Recommendation X.435.

6.3 EDI messaging environment
The environment in which EDI messaging takes place can be modelled as a functional object which is hereafter
referred to as the EDI messaging environment (EDIME). When refined (i.e., functionally decomposed), the EDIME
can be seen to comprise lesser objects referred to as the primary objects of EDI messaging. They include a single
central object, the EDI messaging system (EDIMS), and numerous peripheral objects called EDI messaging users
(EDIMG users).
The structure of the EDIME is depicted in figure 1.

6.4 EDI messaging user
An EDI messaging user (EDIMG user) is a user that engages in EDI messaging. An EDIMG user originates, receives,
or both originates and receives EDIMs. The EDIME contains any number of EDIMG users.
An EDIMG user may be a person or a computer process. An EDIMG user may access the EDIMS through an
access unit.
7 EDI messaging system
7.1 Introduction
The EDI messaging system (EDIMS) is the functional object by means of which all EDIMG users communicate with
one another in EDI messaging.
The EDIMS can be modelled as comprising lesser functional objects which interact with one another. These lesser
objects are referred to as the secondary objects of EDI messaging. They include a single, central object, the message
transfer system (MTS), and numerous peripheral objects of three kinds: EDI user agents (EDI-UAs), EDI message
stores (EDI-MSs), and EDI access units (EDI-AUs).
The structure of the EDIMS is depicted in figure 2. As shown in figure 2, EDI-UAs, EDI-MSs, and EDI-AUs are the
objects by which the EDIMS provides service to EDIMG users.

7.1.1 EDI user agents
An EDI user agent (EDI-UA) is a user agent tailored so as to better assist a single EDIMG user to engage in EDI
messaging. It helps that EDIMG user originate and receive messages containing EDIMs. The EDIMS contains any
number of EDI-UAs.
NOTE – An exact definition of the boundary between the EDI-UA and the EDIMG user is beyond the scope of this part of
ISO/IEC 10021.
7.1.2 EDI message store
An EDI message store (EDI-MS) is a message store tailored so as to better assist a single EDI-UA engage in EDI
messaging. It helps that EDI-UA submit, take delivery of, store, and retrieve messages containing EDIMs.
