(Universal Business Language) A format for exchanging data from one XML business language to another. Based on ebXML Core Components, UBL is designed to provide a common language that acts as an intermediate vocabulary so that one XML vocabulary can interoperate with another. UBL was created to promote e-business over the Internet. Derived from the Common Business Language (CBL), which was sponsored by the U.S. Government, UBL became an OASIS standard in 2004. See ebXML.
