TermBase eXchange (TBX) has provided a successful mechanism for exchanging complex terminological data. Because TBX defines a family of related formats for representing terminological data rather than a single format, it can be adapted to many needs. However, use within commercial production environments has remained limited due to the perception that TBX is too complex for particular use cases. This paper describes the development of a new derivative of TBX, called TBX-Min, that is designed to represent the sorts of columnar tables of terms in two languages widely used by practicing translators, in a TBX-compatible fashion. Through TBX-Min, translators will be able to send and receive simple, machine-processable bilingual terminology while still gaining access to the wider ecosystem of TBX-compliant tools.
