Adding a new locale to CLDR

If you are just adding a new country locale (eg we have a locale for the language), you just need to add the new empty locale file, and Update Survey Tool. Otherwise:

Minimal Structure

Before adding a new locale, you must have the core data: see Core Data for New Locales for the process.

Add Data in SVN

  • Before starting to add a new locale, make sure you have the minimal core data that cannot be added through the Survey Tool. See above.
  • Create the new locale files.  If you are adding a single new language locale, for example, language "xx" as spoken in country "YY", you will need two files:
    • common/main/xx.xml - The main locale file containing the core data.  You can use the template in seed/main/und.xml as a starting point.
    • common/main/xx_YY.xml - An empty country locale containing the identification of xx_YY as a valid locale.  You can use the template in seed/main/und_XX.xml as a starting point.
    • See files are here:
  • Run the XMLValidator tool against these two files to insure validity. The XMLValidator is the java tool: org.unicode.cldr.util.XMLValidator
  • Add these two files to the repository : svn add xx.xml ; svn add xx_YY.xml
  • Add the plural rules common/supplemental/plurals.xml ).c
    Add the day period rules (if you have them ) to common/supplemental/dayPeriods.xml
  • Add the language subtag to <variable id="$language" type="choice"> in
  • If you are adding a new language, add the appropriate default content locale
    to <defaultContent locales="..."> in common/supplemental/supplementalMetadata.xml
    The default content locale is usually the locale where the most people speak the language in question.
  • Send the literate pop information to Rick, or file a bug, if the language is not already in the supplemental data.
  • Also add the English translation for any new languages in  common/main/en.xml
  • Commit all of your work to SVN:
    svn commit -m "cldrbug 9999: Add new locale for xx_YY"

Update Survey Tool

Update the data and restart Survey Tool (Steven, Rick, Mark, or John can do this if you don't have access).
