cldrunicodeorg

cldrunicodeorg is the official hub for the Unicode Common Locale Data Repository (CLDR), a project of the Unicode Consortium that collects, validates, and distributes locale data used to internationalize software. The repository provides centralized data for locale-specific formatting and display, including dates, times, numbers, currencies, units, plural rules, sorting, and locale display names.

Data is organized by locale and subcomponents; data files are maintained in formats suitable for software development, predominantly XML and JSON, and cover areas such as dates and times, numbers and currencies, calendars, time zones, language names, scripts, territories, and collation rules.

The project relies on a global community of linguists, translators, software engineers, and organizations who contribute data, review submissions, and help validate accuracy. Contributions go through a validation process and periodic releases that make the data available for download and use by developers and organizations.

CLDR data is widely used by major software projects and platforms, including ICU, Android, web browsers, and localization pipelines, to ensure culturally appropriate formatting and display across locales. The data supports internationalization efforts across operating systems, applications, and services.

Access and licensing: Data is downloadable from the cldrunicodeorg site and distributed under the Unicode data license, enabling broad reuse with attribution as defined by the license terms.

History and governance: The CLDR project began in the mid-2000s as a centralized effort to standardize locale data and is overseen by the Unicode Consortium with ongoing community involvement. The project continues to evolve through regular data updates and community collaboration.
