The  Common Locale Data Repository, otherwise known as the CLDR, provides key building blocks for software to support the world's languages, with the largest and most extensive standard repository of locale data available, where a locale is a language, spoken in a particular country, written in a particular script. This data is used by a wide spectrum of companies for their software internationalization and localization, adapting software to the conventions of different languages for such common software tasks as:

  • formatting of dates, times, and time zones
  • formatting numbers and currency values
  • sorting text
  • choosing languages or countries by name

The CLDR is hosted by the Unicode Consortium at and run by a committee of developers from around the world. SIL International is one of the organizations that participates on the CLDR committee. More details about the CLDR information we display on ScriptSource can be found in ScriptSource and the CLDR.

If you are knowledgeable about a particular locale, and might like to contribute information, either to the CLDR or to ScriptSource, read Contributing to ScriptSource and the CLDR to learn how to go about it.
