CLDR Releases/Downloads

Each release of the Unicode CLDR is a stable release and may be used as reference material or cited as a normative reference by other specifications. Each version, once published, is absolutely stable and will never change. Implementations may also apply CLDR Corrigenda to a release. Bug reports and feature requests for subsequent versions may be filed at Bug Reports.

Downloads

The following table lists the files for each released version. For license information, see the Unicode Terms of Use; in particular, Exhibit 1. The top two rows have permalinks for the latest version and the latest development version (snapshot). They are followed by the specific release versions. See Key to Header Links.

JSON Data

Repository Access

CLDR files are maintained in a git source code repository at https://github.com/unicode-org/cldr.git .  
There are several ways to access the repository contents.

Simple Browsing

For browsing a particular file for a particular version, or revision history of a particular file, use the GitHub Browser.  For example:

Advanced Git Access

For more access to the source repository, you can use an git client to check out or export LDML files directory from the repository at https://github.com/unicode-org/cldr.git 

Repository Organization

At the top level of each GitHub repository tree, there are a number of special folders, plus a number of platform folders. 

  • common — CLDR data corresponding to the release
    • annotations — annotations and TTS names for characters
    • annotationsDerived — names algorithmically derived based on structure
    • bcp47 — data for unicode locale extensions
    • casing — intended capitalization for various categories in each language, for use by the Survey Tool
    • collation — collation LDML files
    • dtd — the latest XML DTD files for the release
    • main — the main locale-dependent LDML files
    • properties — property files in UCD format
    • rbnf — rule-based number formats
    • segments  — rules for segmenting text
    • subdivisions  — names of region (country) subdivisions.
    • supplemental  — additional files with non-linguistic data.
    • testData — folders of test data for implementations.
    • transforms — data for transliteration and other text transforms
    • uca — customized Unicode collation data
    • validity — data for validating BCP47 identifiers
  • docs — the source of the LDML spec and other documents
  • exemplars/main — preliminary exemplar character data for locales which do not hav e
  • keyboards —source files for the CLDR keyboard data
  • seed — preliminary locales that do not yet have sufficient vetted data.
    • annotations
      casing
      collation
      main
      rbnf
      transforms
      — these folders have the same structure as their counterparts in common. Note that supplemental is not duplicated.
  • specs — deprecated, with contents moved to docs.
  • tools — source for internal tools for processing CLDR data
    • SurveyConsole — (not currently deployed) This is a tool providing an operational dashboard for the Survey Tool
    • c/genldml — The only C language tool, this was used to convert ICU format data into LDML.
    • cldr-apps-watcher — (not currently deployed) This is a tool which will watch the Survey Tool and ensure that it remains operational.
    • cldr-apps —  Survey Tool source code
    • cldr-unittest — Unit tests against the CLDR code in the “java” directory. (Not to be confused with CheckCLDR tests.)
    • java — main source code for the CLDR tooling
    • python — utility Python code
    • scripts — accessory shell scripts, used for CLDR process and Survey Tool deployment

The commondtd, and tools folders are in each release.

POSIX Data

Note: Beginning with CLDR v21, the CLDR project no longer publishs POSIX-format locale sources as part of its distribution.  The POSIX locale generation tools will continue to be made available as a part of the release.  Developers who require POSIX compliant locales can generate them using these tools.

CLDR had historically included reference versions of POSIX-format locale source files that are generated using the default options for each supported locale. The reference versions of POSIX source information contain those data fields that are included in the POSIX specification.

Many operating system platforms provide additional extensions to the minimal POSIX required field set. Individual implementations may require addition of the platform-specific fields or a non-default character repertoire in order to provide full functionality on a given POSIX compliant operating system. As of the current release, the POSIX locale generation tools do not generate such platform-specific extensions, but they can be modified to support this.

CLDR 1.0 Release

The 1.0 version of CLDR is described here for historical interest only. It was hosted on the OpenI18N site before the CLDR project moved to the Unicode Consortium.
