What is the relationship of UBL to ebXML Core Components?
UBL is the first international standards body implementation of the ebXML Core Components Technical Specification (CCTS 2.01, aka ISO 15000-5). The UBL library consists of ebXML CCTS Business Information Entities (BIEs). UBL XML schemas are defined through the application of UBL Naming and Design Rules (NDRs) to an underlying data model mapped to the Core Component types. UBL is also currently working with UN/CEFACT to converge the UBL library with the emerging UN/CEFACT Core Component library.
