JWG 1 was established in the late 80’s as so called “Joint Syntax Working Group (JSWG)” with the UNECE in order to develop and maintain the EDIFACT syntax. Since the publication of the syntax version 1 in 1988, the standard has been revised and amended several times until the current version 4, release 2.
With its publication in 2002, the work in JWG 1 is mainly concentrated on the twice-per-year update of the syntax codes directory (in alignment with the EDIFACT user directories) on the corresponding JSWG website.
