ISO 15924:2022

Overview

ISO 15924:2022 - Information and documentation - Codes for the representation of names of scripts is an international standard published by the International Organization for Standardization (ISO). This standard provides a comprehensive system of codes for the structured representation of script names, making it possible to identify and reference writing systems used in documents, databases, and software. The codes are designed to support activities in terminology, lexicography, bibliography, and linguistics, but their use extends to any application where expressing scripts in a standardized, coded form is required.

ISO 15924:2022 is an essential reference for professionals dealing with multilingual content and globalized information systems, enabling accurate identification and management of textual data across different scripts.

Key Topics

• Script Code Structure:
  ISO 15924 specifies standardized four-letter alphabetic codes (e.g., "Latn" for Latin, "Cyrl" for Cyrillic) and associated numeric codes for representing script names. These codes are carefully constructed to avoid confusion with language and country codes.

• Relationship to Other Standards:
  The script codes complement language codes from the ISO 639 series and country codes from ISO 3166, supporting integration in multilingual and multinational documentation and software.

• Code Assignment and Registration:
  The responsibility for allocating and maintaining script codes lies with an ISO-designated Registration Authority, which follows clear procedures for the addition and management of codes.

• Variants and Aliases:
  Provisions exist for identifying script variants and grouped scripts (aliases), providing flexibility for representing unique or evolving writing systems.

• Change Management:
  To maintain data integrity, any modification to existing script codes is subject to stringent review and is only undertaken for compelling reasons.

Applications

ISO 15924:2022 script codes are critical in several fields where standardized identification of scripts is essential:

• Library and Information Science:
  Libraries and archives use script codes in cataloguing, bibliographic records, and metadata to indicate scripts used in materials, aiding in search, retrieval, and interlibrary loan processing.

• Publishing and Lexicography:
  Publishers and dictionary compilers employ these codes to consistently reference the script of language materials across editions and platforms.

• Linguistics and Academic Research:
  Script codes support linguistic databases, corpora, and research, enabling accurate annotation of text samples and comparative studies.

• Digital Content and Software Development:
  Software and web applications leverage script codes for content encoding, font selection, rendering engines, and localization to support multiple scripts within user interfaces.

• Internationalization and Localization:
  Multinational organizations and developers reference ISO 15924 codes in standards-compliant workflows for web development, document exchange (such as XML markup), and data interoperability.

Related Standards

ISO 15924:2022 works in conjunction with several key international standards:

• ISO 639-1 / ISO 639-2 / ISO 639-3: Codes for the representation of names of languages.
• ISO 3166-1: Codes for the representation of names of countries and their subdivisions.
• ISO/IEC 10646: Information technology - Universal coded character set (UCS), fundamental to Unicode.
• ISO/IEC TR 15285: Operational model for characters and glyphs in IT systems.

ISO 15924:2022 is a vital component of the global information infrastructure, ensuring that scripts from around the world are represented in a compatible, reliable, and standardized manner for use in information management, IT applications, and cross-cultural communication. For organizations pursuing excellence in multilingual content processing, adoption of ISO 15924:2022 ensures broad compatibility, accuracy, and future-proofed information handling.
