Universal Business Language v2.1 (#UBL 2.1) published by the UBL TC

We are pleased to announce the approval and publication of a new Committee Specification by the members of the OASIS Universal Business Language (UBL) TC:

Universal Business Language Version 2.1
Committee Specification 1
29 June 2013


This specification defines the Universal Business Language (UBL), version 2.1. UBL is a generic XML interchange format for business documents that can be restricted or extended to meet the requirements of particular industries.

This version includes 65 business documents used in the procurement and transportation domains (e.g.: invoices, purchase orders, waybills, transportation status messages, etc.).

TC Description:
The OASIS Universal Business Language technical committee is defining a royalty-free library of standard electronic XML business documents for various domains. Development is with participation from a variety of industry data standards organizations. UBL is designed to plug directly into existing business, legal, auditing, and records management practices, eliminating the re-keying of data in existing fax- and paper-based supply chains and providing an entry point into electronic commerce for small and medium-sized businesses.

The prose specification and related files are available here:

Our congratulations to the TC on achieving this milestone.
