This chapter briefly introduces the EDIFACT standard and InterSystems IRIS® support for EDIFACT. It contains the following sections:
Introduction to EDIFACT
The Electronic Data Interchange For Administration, Commerce, and Transport standard (EDIFACT) is also known as the International Standards Organization (ISO) Standard ISO 9735-6.
United Nations rules for Electronic Data Interchange For Administration, Commerce and Transport comprise a set of internationally agreed standards, directories, and guidelines for the electronic interchange of structured data, and in particular that relate to trade in goods and services between independent, computerized information systems.
InterSystems IRIS Support for EDIFACT Documents
InterSystems IRIS supports EDIFACT documents as virtual documents. A virtual document is a kind of message that InterSystems IRIS parses only partially. This kind of message has the standard production message header and the standard message properties such as ID, Priority, and SessionId. The data in the message, however, is not available as message properties; instead it is stored directly in an internal-use global, for greater processing speed.
InterSystems IRIS provides tools so that you can access values in virtual documents, for use in data transformations, business rules, and searching and filtering messages. For background information, see Using Virtual Documents in Productions.
