Classification notation

Each preferred or guide term in the TGDT is provided with an alphanumeric classifica-

tion code, which indicates its placement within the hierarchical structure of genus-species

relations. Classification codes are formed by appending to the facet’s letter a period and

decimal number for each branch taken in the hierarchy to arrive at the term itself. For ex-

ample, the term typesetting equipment has the classification O.3.5.44.78; its immedi-

ately broader term, equipment – its ‘parent’ – is classified as O.3.5.44.

These classification codes are intended primarily as a means to quickly move from a

term’s entry in the alphabetic listing to its corresponding position in the systematic list-

ing, but may also be used as a notational shorthand in indexing or retrieval applications.
