The CRA's Controlled Subject Vocabulary (CRA CSV) has been developed to help Content managers, Librarians and Metadata developers in the Agency to select controlled subject terms for metadata requirements under TBITS 39.1 & 2. The CRACSV is to be used as a source of standardized terminology for the indexing and retrieval of CRA information resources in various formats, once it has been approved by Library and Archives Canada. Its main function to standardize the external form and meaning of index terms, thus ensuring that a particular concept or subject will always be represented in the same way in CRA Web site metadata resources.
