Machine-Readable Terminology Interchange Format - An ambitious and maturing standard designed to handle the needs of ornthologists and language specialists. It is an offshoot of earlier work done by the TEI ('Text Encoding Initiative') and the Localisation Industry Standards Association (LISA). The 150 data categories used in MARTIF are standardized as
ISO 12620. MARTIF is designed for concept-based systems. In their words: "[MARTIF] does not match the needs of non-concept-oriented approaches to terminology, i.e. lexicographic and NLP approaches, because MARTIF presupposes a
concept orientation rather than a
word orientation"
