Milestone Schedule

CLDR Survey Tool


Translations in the Unicode Common Locale Data Repository are gathered and processed via what is called the Survey Tool, an online tool that can be used to view data for different languages and propose additions or changes. This tool provides a way to propose new localized data, see what others have proposed, and communicate with them to resolve differences. During each submission period, contributors from Unicode Consortium members, other organizations and the public at large are invited to review the data for their languages and countries, and propose new translations of terms or modifications, including language translations entirely new to the repository. For the release schedule, see CLDR Project.

New Features

To see a summary of the new features and data fields in the CLDR v24 Survey tool, refer to the What's New document.


You don’t need an account to view data for a particular language. If you wish to propose changes or additions, you will need an account: see Survey Tool Accounts.

If you would like to add data for a new locale, see Adding New Locales.


For an overview of how the Survey Tool works, see the Survey Tool Guide. For guidelines to translators, see Translation Guidelines.


For a summary of how to most effectively contribute translations, see Walkthrough.

FAQ & Known Bugs

For frequently-asked questions, and a list of known bugs, see FAQ&Known Bugs. If you find a problem, you may want to review Known Bugs to see whether it has already been reported (and whether there is a work-around). If not, or if you have suggestions for improvements, please file a bug using the Feedback link at the bottom of each window. If there are other issues, you can raise them on the Unicode CLDR Mailing List.

Resolving Differences among Translators

After the data submission phase, any differences in the submitted data will be resolved according to the data resolution process. However, even during the submission phase, you should collaborate with the other translators where you have questions, via email and the forums.
