Specification for a modern SEF implementation
XSEF is similar to npm in that they are both package managers.
- Configure Schemas between Business to Business Trading Channels / Message Channels
- Define, in a deterministic way, what is a valid and what is an invalid data interchange message
- Utilize modern techniques and applications to leverage performant featureset while still being small
- Enable easier B2B onboarding for companies by having a decentralized package management tool for accessing configurations
- an Infrastructure as Code approach to dealing with onboarding new business relations
- configuration management
- platform independence
- hermetic and deterministic builds
- reliability and safety
The eXtended Standard Exchange Format ('XSEF') is an open-standard file format
- files ending with the extension .xsef -
That defines the format and the format and implementation guideline for proprietary and standard EDI documents.
XSEF holds key advantages over other file formats in that it is designed for EDI
XSEF files are immediately useable by both users and computers They're small files and are easily transmitted easily via the web You can edit them with either a text editor or an XSEF manager XSEF is an open standard, so you can create and distribute XSEF files without special permissions or royalties under the Mozilla Public License 2.0.
The sections may appear in any order, with these exceptions: the .VER, if present, must be first. The .INI section must be the first section in the file if there is no .VER, or the second section if there is a .VER. Nothing may appear before these, including a comment. The .STD record, if used, must appear before .SETS. Example
.VER 1.6

The standard or implementation name (INVPO in the example above), generally the same as the filename of the SEF file.

The Functional Group Version, Release and Industry code which will identify the standard in any Functional Group Envelope Header Segment. Each code is separated by a space. In the example, there is no industry code. With an industry code, this field might contain: 003 030 UCS
-
The responsible agency code, which identifies the standards organization in the Functional Group Header: GC = GENDOD T = for T.D.C.C. (EDIA) TD = TRADACOMS UN = for UN/EDIFACT X = for ASC X12 (DISA)
-
The standard on which this implementation guidelines is based.

The description (title) of the implementation guideline.
The .VER section identifies the version and release of SEF, which is currently 1.6. It should be the first record in the file. If the .VER section is not present, SEF 1.0 is assumed.
These sections can occur anywhere after the .INI section. The .PRIVATE section provides a place for companies to place information that is useful to themselves but is of no interest to others. The .PUBLIC section marks the end of the private section.
.STD is only included for these standards: • Newer EDIFACT standards in which groups have position numbers • Newer EDIFACT and X12 standards that have repeating elements • Fixed-length standards like GENCOD.
The .SETS section defines the transaction set or message directory, including: • Each transaction set or message in the standard. • For each transaction set or message, it lists each segment reference in the order in which it appears. It also describes the requirement and quantity for each segment when it appears in a particular position in that set. • Loops, groups, and tables are also set up. In this section, all information about loops, groups, and segments is hierarchical: for example, the quantity for a PER segment only applies to that particular position in that particular set or message.
The .COMS section is the standard's composite data element dictionary: a list of all composites in the standard. It includes: • The composite name (C001, etc.). • A list of each subelement reference it contains, in order. • Each subelement's ID and requirement when used in this position of this composite. • Subelement relationals used within the composite. • Subelement repeat counts. • Masks for variations in the structure of a composite. If the standard has no composites, this section will be omitted.
The .ELMS section is the standard's data element dictionary: a list of each element, its type, and its minimum and maximum data value lengths.
The .CODES section is a list of each element that has code values, along with its code values. It also provides information about code sets.
