Term Base eXchange is the open, XML based standard for exchanging structured terminological data. TBX was submitted to the International Organization for Standardization (ISO) on February 21, 2007, for adoption as an ISO standard. It is now being worked on within an ISO context (as ISO DIS 30042) and it is anticipated that it will be accepted by ISO Technical Committee 37 as a draft international standard (DIS) in Q2 2008. The version submitted to ISO is available on-line in XHTML format.
