What it is and what it does
Weblate Language Data is a reference dataset of language definitions, plural rules, and locale mappings maintained by the Weblate localization platform. It bundles language codes, names, plural equations aligned with CLDR standards, locale aliases, and country-specific defaults into a Python package that can be imported directly or used as a Django application. The package also includes Gettext translations for language names themselves.
The data originates from multiple authoritative sources—CLDR, Gettext standards, and the translate-toolkit—and is manually curated to handle edge cases and legacy locale codes. It's designed primarily for localization tools and frameworks that need canonical, standards-aligned language metadata, though any Python project working with internationalization can import and use the definitions.
Use it for
- Populate language selection dropdowns in a web application with canonical language names and codes.
- Resolve non-standard or legacy locale codes to their modern equivalents using the aliases dataset.
- Determine the correct plural form rules for a given language when generating or parsing Gettext catalogs.
- Map user-selected countries to their default language locales for initial UI language detection.
- Build a localization workflow tool that needs CLDR-compliant language and plural metadata.
