Members of the OASIS Universal Business Language TC  have recently approved a Special Majority Ballot  to advance Universal Business Language Version 2.2 as a Candidate OASIS Standard (COS). The COS now enters a 60-day public review period in preparation for the member call to consider its approval as an OASIS Standard.
The Universal Business Language (UBL) is an open library of standard electronic XML business documents for procurement and transportation such as purchase orders, invoices, transport logistics and waybills. 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.
Version 2.2 is completely backward-compatible with UBL 2.0. UBL is freely available to everyone without legal encumbrance or licensing fees.
The TC has received 3 Statements of Use from JAVEST, the eSENS eTendering pilot, and the Norwegian Agency for Public Management and eGovernment (Difi) .
