First public review for Version 2.4 ends April 5th
OASIS and the OASIS Universal Business Language TC are pleased to announce that Universal Business Language Version 2.4 is now available for public review and comment. This is the first public review for Universal Business Language Version 2.4.
About the specification draft:
UBL is the leading interchange format for business documents. It is designed to operate within a standard business framework such as ISO/IEC 15000 (ebXML) to provide a complete, standards-based infrastructure that can extend the benefits of existing EDI systems to businesses of all sizes. The European Commission has declared UBL officially eligible for referencing in tenders from public administrations, and in 2015 UBL was approved as ISO/IEC 19845:2015.
Specifically, UBL provides:
– A suite of structured business objects and their associated semantics expressed as reusable data components and common business documents.
– A library of schemas for reusable data components such as Address, Item, and Payment, the common data elements of everyday business documents.
– A set of schemas for common business documents such as Order, Despatch Advice, and Invoice that are constructed from the UBL library components and can be used in generic procurement and transportation contexts.
UBL v2.4 is a minor revision to v2.3 that preserves backwards compatibility with previous v2.# versions. It adds new document types, bringing the total number of UBL business documents to 93. As with previous UBL releases, the UBL 2.4 library is designed to support the construction of a wide variety of document types beyond those provided in the 2.4 package.
