Common Locale Data Repository
project of the Unicode Consortium to provide locale data in XML format for use in computer applications
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.
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 more than 400 languages.
“Common Locale Data Repository” enters the record as project of the Unicode Consortium to provide locale data in XML format for use in computer applications. Crown Archives preserves that source wording while asking what Common, Locale and Data can confirm, complicate or overturn.
Why this record matters
“Common Locale Data Repository” is worth following because a concise public description often conceals a longer documentary argument. Here, Common, Locale and Data provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q2986828. None of the 1 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
