ISO 15924

ISO 15924, Codes for the representation of names of scripts, defines two sets of codes for a number of writing systems (scripts). Each script is given both a four-letter code and a numeric one.[1] Script is defined as "set of graphic characters used for the written form of one or more languages".[1]

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). Preference is given to the 639-2 Bibliographical codes, which is different from the otherwise often preferred use of the Terminological codes.[1]

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. For example, they can be used in HTML and XML to help Web browsers determine which typeface to use for foreign text. 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.

Maintenance

ISO has appointed the Unicode Consortium as the Registration Authority (RA) for the standard. In 2004, the RA appointed Michael Everson to act as Registrar. The Registrar works with a Joint Advisory Committee (JAC) in developing and implementing the standard.[2] The JAC contains six members: the Registrar, one member from the Library of Congress, one from Standards Norway, one from the French Encyclopaedia Universalis, an officer of Unicode, and a member of Unicode. These individuals represent the interests of the ISO 15924 RA, the ISO 639-2 RA, ISO Technical Committee 37, ISO Technical Committee 46, and the ISO Coded Character Set Sub-Committee, ISO/IEC JTC1/SC2.[3]

Relations to other standards

The following standards are referred to as indispensable by ISO 15924.

  • ISO 639-2:1998 Codes for the representation of names of languages — Part 2: Alpha-3 code
  • ISO/IEC 9541-1:1991 Information technology — Font information interchange — Part 1: Architecture
  • ISO/IEC 10646-1:2000 Information technology — Universal Multiple-Octet Coded Character Set (UCS)

For definition of font and glyph the standard refers to

  • ISO/IEC 9541-1:1991

Around 146 scripts are defined in Unicode. Through a linkpin called "Property Value Alias", Unicode has made a 1:1 connection between a script defined, and its ISO 15924 standard. See Script (Unicode).
