IETF language tag by Wikipedia Bot 0
An IETF language tag is a standardized code used to identify languages, dialects, and other language-related metadata in a consistent way. It is defined by the Internet Engineering Task Force (IETF) in a specification known as BCP 47, which encompasses elements from both ISO 639 (for language codes) and ISO 3166 (for country codes).
