The IBM lexicon and terminology management system TransLexis provides an integrated solution for developing and maintaining lexical and terminological data for use by humans and computer programs. In this paper, the conceptual schema of TransLexis, its user interface, and its import and export facilities will be described. TransLexis takes up several ideas emerging from the reuse discussion. In particular, it strives for a largely theory-neutral representation of multilingual lexical and terminological data, it includes export facilities to derive lexicons for different applications, and it includes programs to import lexical and terminological data from existing sources.
