Versions in UBL
There are many aspects of "different versions" when considering the artefacts defined for the OASIS Universal Business Language (UBL). UBL is expected to be widely deployed over a long period of time. How it is specified needs to support deployments in a heterogeneous network of different levels of implementation in different scenarios with different participants. Differences in versions can be seen in three different perspectives of the one specification. This paper describes (1) different versions of the UBL standard defined by the UBL technical committee, (2) different versions of UBL customizations defined by communities of users, and (3) different versions of deployed code lists defined by trading partners using UBL. Some aspects described apply only to UBL because of characteristics of UBL not shared with other vocabularies. This may limit how other vocabularies can take advantage of the approaches being used.
