The EDIFACT reference provides the most comprehensive EDIFACT repository for simplifying XML and legacy data integration projects, providing detailed information on all EDIFACT structures. The enhanced EDIFACT reference site includes the following features:

• All EDIFACT data models in a Javadocs format.
• Combines references to the control and segments (e.g. UNB, UNH) with the content segments (e.g. DTM, QTY) so all searching can be done in one place.
• Graphical trees of the segments used in a message are available.
• Cross references show which tables, elements, segments and messages are available in each version, making it easy to see what has changed.
• Includes all versions of the base standard from D93A onward, including the EDIFACT B and even C variants.
• Syntax versions 3, 4 and 4.1 are all included

Using this along with the annotated output of the Stylus Studio native EDI adapter and EDI Tools can simplify the task of building EDIFACT applications and diagnosing trouble spots.
