TBX (TermBase eXchange) is an open, XML-based standard developed by LISA (Localization Industry Standards Association) and currently maintained by ISO (ISO 30042) for the exchange of terminology data. It is the industry-standard format for sharing terminology databases between different computer-assisted translation (CAT) tools and terminology management systems. Because it is based on XML, it provides a structured, platform-independent way to represent complex terminological information, including metadata, definitions, grammatical information, and cross-references. By using TBX, organizations can ensure interoperability between various translation environments, preventing vendor lock-in and facilitating the seamless migration of glossaries and termbases across different software platforms. It is widely used by professional translators, localization engineers, and terminologists to maintain consistency in multilingual documentation and technical writing projects.
