Framework EDI (FREDI) refers to implementation guidelines for
verification of correct syntax. Only the following types are used
by FREDI to verify EDI documents:
Standard Reference Library. This is an internal library
containing versions of the ASC/X12 or UN/EDIFACT standard that FREDI
will reference to verify the syntax of, or build, EDI documents.
Standard
Exchange Format (SEF). Files that follow the SEF standard
contain syntax information that FREDI references to verify, or
build, EDI documents. If these files are provided, they will
be used first before referencing the Standard Reference Library.
