GOLD (General Ontology for Linguistic Description) is an ontology for descriptive linguistics. It gives a formalized account of the most basic categories and relations used in the scientific description of human language. GOLD was first introduced by Farrar and Langendoen (2003). Originally, it was envisioned as a solution to the problem of resolving disparate markup schemes for linguistic data, in particular data from endangered languages. Meanwhile, GOLD is much more general and can be applied to all languages.
