The subject of the thesaurus is the practice and teaching of yoga. This vocabulary was created for the completion of an assignment for module INM303 Information Organisation. The thesaurus is not based on existing resources to index and is therefore entirely artificial. In this document, you will find a taxonomy structure with one section developed to the lowest level – other sections are shown up to three levels below the first terms – the thesaurus fragment for this section, and a short reflection on the building process.
