This standard provides a system whereby uses of plants (in their cultural context) can be described, using standardised descriptors and terms, and attached to taxonomic data sets. It resulted from discussions at the International Working Group on Taxonomic Databases for Plant Sciences (TDWG) between 1989 and 1992. Users and potential users of the standard include: economic botanists and ethnobotanists whose purpose is to record all known information about the uses of a taxon; educationalists, taxonomists, biochemists, anatomists etc. who wish to record plant use, often at a broad level; economic botany collection curators who need to describe accurately the uses and values of specimens in their collections; bibliographers who need to describe plant uses referred to in publications and to apply keywords consistently for ease of data retrieval. While this standard is still in use, it is no longer actively maintained (labelled as prior on the TDWG website).
