The complexity of the 1948 Berlin airlift required the development of concepts and methods to exchange, sometimes over a 300 baud teletype modem, vast quantities of data and information about transported goods.
One such real-time system was the London Airport Cargo EDP Scheme (LACES) at Heathrow Airport, London, UK, in 1971.
The increase of maritime traffic and problems at customs similar to those experienced at Heathrow Airport led to the implementation of DTI systems in individual ports or groups of ports in the 1980s. ==Standards== EDI provides a technical basis for automated commercial "conversations" between two entities, either internal or external.
In 1996, the National Institute of Standards and Technology defined electronic data interchange as "the computer-to-computer interchange of strictly formatted messages that represent documents other than monetary instruments.
In most cases, these non-internet transmission methods are simply being replaced by Internet protocols, such as FTP, HTTP, telnet, and e-mail, but the EDI documents themselves still remain. In 2002, the IETF published RFC 3335, offering a standardized, secure method of transferring EDI data via e-mail.
However, the IETF has published several informational documents (the "Applicability Statements"; see below under Protocols) describing ways to use standard Internet protocols for EDI. As of 2002, Walmart has pushed AS2 for EDI.
On July 12, 2005, an IETF working group ratified RFC4130 for MIME-based HTTP EDIINT (a.k.a.
For this reason, EDI can be an important component of just-in-time production systems. According to the 2008 Aberdeen report "A Comparison of Supplier Enablement around the World", only 34% of purchase orders are transmitted electronically in North America.
