EDI Message Standards – an Overview

Introduction

EDI message standards are useful for electronically exchanging structured data between business partners. Various organizations such as UN, ANSI, DIN or VDA define the EDI message standards. The most commonly used format is the UN/EDIFACT message (United Nations rules for Electronic Data Interchange for Administration, Commerce and Transport). Related to this format, a number of variations exist (usually defined by an industry, e.g. EANCOM). These dialects are usually referred to as subsets.

Other important message formats are ANSI.X12 (The American National Standards Institute Accredited Standards Committee X12). This standard is mainly used in North America, ODETTE (Standard of the European Automotive Industry) and VDA (Format of the Association of the German Automotive Industry). The TRADACOMS standard is the predecessor of EDIFACT in the UK. HIPPA (Law on Control and Safety of Medical Insurance) was specifically developed for the compliance of activities in health authorities and for legislation purposes.
