The Common Locale Data Repository (CLDR) is a project of the Unicode Consortium to provide locale data in XML format for use in computer applications. CLDR contains locale-specific information that an operating system will typically provide to applications. CLDR is written in the Locale Data Markup Language (LDML).
CLDR is maintained by a technical committee which includes employees from IBM, Apple, Google, Microsoft, and some government-based organizations. The committee is chaired by Mark Davis of Google; Annemarie Apple of Google is vice-chair.[4]
Details
Among the types of data that CLDR includes are the following:
- Translations for language names
- Translations for territory and country names
- Translations for currency names, including singular/plural modifications
- Translations for weekday, month, era, period of day, in full and abbreviated forms
- Translations for time zones and example cities (or similar) for time zones
- Translations for calendar fields
- Patterns for formatting/parsing dates or times of day
- Exemplar sets of characters used for writing the language
- Patterns for formatting/parsing numbers
- Rules for language-adapted collation
- Rules for spelling out numbers as words
- Rules for formatting numbers in traditional numeral systems (such as Roman and Armenian numerals)
- Rules for transliteration between scripts, much of it based on BGN/PCGN romanization
The information is currently used in International Components for Unicode, Apple's macOS, LibreOffice, MediaWiki, and IBM's AIX, among other applications and operating systems.
CLDR overlaps somewhat with ISO/IEC 15897 (POSIX locales). POSIX locale information can be derived from CLDR by using some of CLDR's conversion tools.
The CLDR covers 400+ languages.[5]

In particular, the XML is designed so that you can read in a CLDR XML file and interpret it as an unordered list of <path,value> pairs, called a CLDRFile internally. These path/value pairs can be added to or deleted, and then the CLDRFile can be written back out to disk, resulting in a valid XML file. That is a very powerful mechanism, and also allows for the CLDR inheritance model.
