If a user wants to know something about a term used in the, say, ERN standard, it would make that user's life more complicated if (s)he has to look at terms that are only used in the, say, DSR or MLC standards. Therefore, DDEX provides an ERN-specific data dictionary that contains only those terms and composites used in the ERN standard. The same applies to all DDEX standards.


From September 2019 onwards, the Data Dictionary for each standard will be provided in two editions: a "structural" edition that contains all information for the tags used in the messages (syntax and semantics) with the exception of the allowed value sets. These allowed value sent are provided in a separate "AVS" edition.


Is there a complete data dictionary available?
