Culture is both the conventional conduct and ideologies of a given community. Culture may also refer to:

  • A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture media under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used extensively as a research tool in molecular biology.
  • Microbial food cultures are a group of microorganisms such as bacteria, fungi, and mold used in the food and beverage industry for processing food items. Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. →microbe, micro-organism
  • Organizational culture, also known as corporate culture, in management
  • Archaeological culture, in archaeology, a term attributed to human activity and also to a consistently recurring assemblage
  • Animal culture, aspects resembling culture in non-human animals
  • IETF language tags, used in computer internationalization and localization to identify a "culture" - the combination of language and peculiarities of geographical location in computing (like en-UK, en-US, de-AT, de-DE, fr-BE)

An IETF BCP 47 language tag is a code to identify human languages. For example, the tag en stands for English; es-419 for Latin American Spanish. To distinguish language variants for countries, regions, writing systems etc., IETF language tags combine subtags from other standards. The tag structure has been standardized by the Internet Engineering Task Force (IETF) in Best Current Practice (BCP) 47; the subtags are maintained by the IANA Language Subtag Registry. IETF language tags are used by computing standards such as HTTP, HTML, XML, and PNG.

  • The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol-related symbols and Internet numbers.

IETF language tags were first defined in RFC 1766, edited by Harald Tveit Alvestrand, published in March 1995. The tags used ISO 639 two-letter language codes and ISO 3166 two-letter country codes, and allowed registration of whole tags that included variant or script subtags of three to eight letters.

In January 2001, this was updated by RFC 3066, which added the use of ISO 639-2 three-letter codes, permitted subtags with digits, and adopted the concept of language ranges from HTTP/1.1 to help with matching of language tags.

The next revision of the specification came in September 2006 with the publication of RFC 4646 (the main part of the specification), edited by Addison Philips and Mark Davis and RFC 4647 (which deals with matching behaviour). RFC 4646 introduced a more structured format for language tags, added the use of ISO 15924 four-letter script codes and UN M.49 three-digit geographical region codes, and replaced the old registry of tags with a new registry of subtags. The small number of previously defined tags that did not conform to the new structure were grandfathered in order to maintain compatibility with RFC 3066.

The current version of the specification, RFC 5646, was published in September 2009. The main purpose of this revision was to incorporate three-letter codes from ISO 639-3 and 639-5 into the Language Subtag Registry, in order to increase the interoperability between ISO 639 and BCP 47.
