The three major components of EDIFACT are a standard syntax for structuring data, i-EDI (interactive EDI), and standard messages to accommodate interaction among various industries and countries.
The EDIFACT standard was developed by the United Nations. Further development of the standard is also overseen by that organization’s Centre for Trade Facilitation and Electronic Business. The standard is sometimes seen as UN/EDIFACT.
XML/EDIFACT, defined in ISO TS 20625, specifies a way for XML-based systems to work with EDIFACT messages.
