The EDIFACT standard provides
IFT+3+NO MORE FLIGHTS'
Note: The line breaks after each segment in this example have been added for readability. There are typically no line breaks in EDI data.
UNH+1+PAORES:93:1:IA’- This is the header segment which is required at the start of every message. This code specifies that the message name and version is PAORES 93 revision 1 and it was defined by the organisation IA (IATA).
IFT+3+NO MORE FLIGHTS’ - This is an 'Interactive Free Text' segment containing the text 'NO MORE FLIGHTS'
UNT+13+1’ - This is the tail segment. It indicated that the message sent contains 13 segments.
A group or segment can be mandatory (M) or conditional (C) and can be specified to repeat. For example, C99 indicates between 0 and 99 repetitions of a segment or group, while M99 signifies between 1 and 99 repetitions.
A group, like a message, is a sequence of segments or groups. The first segment or group beneath a group must be mandatory, and the group should be made conditional if the logic of the situation demands it.
There is an apparent battle between XML and EDIFACT. An equivalent XML message has a larger file size than an EDIFACT message, but it is easier for users to read (although this is not necessary because the contents are created to be read by computers). Another possible explanation is that compatibility is being favored over performance, since more tools exist to work with XML data than with EDIFACT. EDIFACT-messages can be as much as one tenth the size of XML-messages. That makes XML less attractive for very high volume applications.
An advantage of EDIFACT is the availability of agreed message-contents, which XML must leverage to develop its own similar agreed contents. RosettaNet is one of the emerging XML standards and is widely used in semiconductors and high tech industries.
UBL is another currently being adopted by Scandinavian governments as a legally required standard for sending invoices to governments, and was enforced in February 2005 that all invoices to the Danish government must be sent in an electronic format.
However, EDIFACT is likely to remain the most widely used in high tech, civil aviation, retail and tourism industries, due to the amount of software that leverages the standard, and the need for integration between new systems and legacy systems.
Europe has a large EDIFACT installed base because it adopted the technology early, while the Asian region adopted B2B in later implementations and is therefore using more XML standards.
EDIFACT will grow further in Europe's energy market where it is a current requirement.
Simplifying Complexities: Multifaceted. Complex. Archaic. These are terms used by many in the life reinsurance sector to describe the industry's inability to reduce complexity and embrace data quality. Are standards the solution?
