ISO 15924, Codes for the representation of names of scripts, defines two sets of codes for a number of writing systems (scripts). A writing system is a type of Symbolic system used to represent elements or statements expressible in Language. Each script is given both a four-letter code and a numeric one.

Script is defined as "set of graphic characters used for the written form of one or more languages". So scripts that are not (yet) "used for the written form of one language" are explicitly excluded.

Where possible the codes are derived from ISO 639-2 where the name of a script and the name of a language using the script are identical (example: Gujarātī ISO 639 guj, ISO 15924 Gujr). ISO 639-2 is the second part of the ISO 639 standard, which lists codes for the representation of the names of languages Preference is given to the 639-2 Bibliographical codes, which is different from the otherwise often favored use of the Terminological codes.

4-letter ISO 15924 codes are incorporated into the Language Subtag Registry for IETF language tags and so can be used in file formats that make use of such language tags. IETF language tags are defined by BCP 47, which is currently RFC 4646 and RFC 4647 For example, they can be used in HTML and XML to help Web browsers determine which typeface to use for foreign text. HTML, an initialism of HyperText Markup Language, is the predominant Markup language for Web pages It provides a means to describe the structure Don't change "Extensible" A web browser is a software application which enables a user to display and interact with text images videos music games and other information typically located on a In Typography, a typeface is a set of one or more Fonts designed with stylistic unity each comprising a coordinated set of Glyphs A typeface usually comprises This way one could differentiate, for example, between Serbian written in the Cyrillic (sr-Cyrl) or Latin (sr-Latn) script, or mark romanized text as such.

ISO has appointed the Unicode Consortium as the Registration Authority for the standard. The Unicode® Consortium ( Unicode Inc) the non-profit organization that coordinates the development of the Unicode ™ Standard has the ambitious goal of eventually In 2004, the Registration Authority appointed Michael Everson to act as Registrar. Michael Everson (born January 9, 1963) is a linguist, script encoder, typesetter, and Font designer. [1]
