EDI messaging (EDIMG)
EDIM is transferred as X.400 message content accompanied by an envelope (which
conforms to P1 protocol). The format of the message content is similar to, but not the
same as, a P2 message. In addition to the MTS, the EDIMS also consists of numerous
peripheral objects of three kinds: EDI user agents (EDI-UAs), EDI message stores
(EDI-MSs), and EDI access units (EDI-AUs). These peripheral objects can be viewed
as access points for EDI users.
EDI messaging (EDIMG). The exchange of EDI messages (EDIMs) and EDI notifications
(EDINs). Both are information objects specified in CCITT Recommendation X.435.
EDI-MS (EDI message store). An X.400 MS that is tailored to better assist a single EDI-UA
to engage in EDI messaging.
EDI-UA (EDI user agent). An X.400 UA that is tailored to assist an EDIMS user to engage
in EDI messaging.
EDIFACT (Electronic Data Interchange for Administration, Commerce, and
Transport). Trade document format developed in 1988 by the United Nations
Economic Commission of Europe (UNECE). EDIFACT is generally accepted
worldwide as the de facto standard for an EDI interchange.
EDIM (EDI message). Mechanism used to transfer an EDI interchange between originator
and recipient(s). An EDIM consists of a heading and body. The heading contains
information that describes the EDI interchange. The body consists of one primary body
part and, optionally, one or more additional body parts. The primary body part contains
a single EDI interchange (which may be original or forwarded). Additional body parts
contain information related to the EDI interchange, such as drawings or explanatory
text.
EDIM responsibility. An EDIM cannot leave the EDI messaging system unless its
responsibility is accepted by some user (recipient). When a user accepts responsibility,
the body parts of that message are made available to the user by the associated EDI-UA,
EDI-MS, or PDAU (which received the EDIM on behalf of the user).
EDIMS user. An X.400 user that engages in EDI messaging. An EDIMS user originates or
receives (or both originates and receives) EDIMs. An EDIMS user may be a person or a
computer process. An EDIMS user may access the EDI messaging system directly
through an EDI user agent or access unit, or indirectly through an EDI message store.
Note that each EDIM contains only one EDI interchange (which may or may not have
been forwarded).
EDIN (EDI notification). A notification indicating the disposition of an EDIM received. An
EDIN can be requested by the originator of an EDIM when the EDIM is sent. The
EDIN is generated by the EDI-UA, EDI-MS, or PDAU associated with the recipient.
There are three possible conditions that can be requested and reported on: forwarded
notification (FN), negative notification (NN), and positive notification (PN). Each type
of notification relates to acceptance or refusal of responsibility for the EDIM by the
recipient. See also forwarded notification, negative notification, and positive
notification.
