The Common Locale Data Repository CLDR provides key building block for software to support all the languages of the world, is maintain and modified by UNICODE consortium.
CLDR is the largest and most extensive standard repository of locale data. Its goal is to gather basic linguistic information for various "locales," essentially combinations of a language and a location, so that this data will be used for software internationalization and localization. This is achieved by adapting a software to the conventions of different languages for such common software tasks as formatting of dates, times, time zones, numbers, and currency values; sorting text; choosing languages or countries by name; and many others. The basic lists that CLDR gathers are:
1. Dates formats
2. Time Zones
3. Number formats
4. Currency formats
5. Measurement System
6. Collation Specification
7. Translation of names for language, territory, script, time zones, currencies
