EDI Standards
The basic concept of EDI is that companies agree to a
standardised format of EDI messages which are then
unambiguously exchanged using a reliable, connection-oriented
computer network delivery service.
There have been two proposed EDI standards:
- ANSI X.12
- developed in the US and widely adopted, although not an
international standard. Will eventually (supposedly) be replaced
by:
- EDIFACT
- (EDI For Administration, Commerce and Transport), originally
developed by the U.N. (?) and submitted to ISO for ratification as
an international (and hence Australian) standard.
In EDI, an interchange is made up of one or more
messages (or possibly functional
groups containing messages of the same type), which in
turn are composed of segments built up from one or
more single or composite data
elements.
