This is a revised charter for the formation of a vocabulary management task group working under the TDWG TAG. It will focus on requirements for the creation and management of basic vocabularies for biodiversity informatics. The scope includes provision of a framework, tools, best practices and routines starting with the definition of individual vocabulary concepts. This task group will not include the development of ontological relationships between concepts but provide the foundation to support such activities. The overall objective is to support activities for developing basic vocabularies by reusing as far as possible concepts/terms defined by the existing TDWG and other related standards.
