Universal Business Language V2.2 from the #UBL TC is now an OASIS Committee Specification

OASIS is pleased to announce that Universal Business Language Version 2.2 from the OASIS Universal Business Language TC [1] has been approved as an OASIS Committee Specification.

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.

This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.
