The ISO EDI conceptual model activity and its relationship to OSI Available to Purchase

The developing ISO edi conceptual model and its relationship to OSI are described. The term “edi” (lowercase) contrasts with the familiar EDI (Electronic Data Interchange) and its connotation to syntax‐specific standards, such as X12 and EDIFACT. The edi model will define common structures, services, and processes that X12 and EDIFACT could adopt. OSI is of interest to edi because of its potential services to help enable “open edi”—global interoperability, across EDI functional groups. A sidebar describes the CCITT standard X.edi and its use of OSI services.
