The TBX framework defined by ISO 30042 is designed to support various types of processes involving terminological data, including analysis, descriptive representation, dissemination, and interchange (exchange), in various computer environments. The primary purpose of TBX is for interchange of terminological data. It is limited in its ability to represent presentational markup. Intended application areas include translation and authoring. A previous version (ISO 30042:2008) has been marked as "to be revised", with this version listed as under development and also under publication.
