## What it is
The Unicode Common Locale Data Repository (CLDR) is the largest standard repository of locale data supporting software internationalization across 100+ languages. It includes structured locale data files, the LDML specification (UTS #35), and Java-based tools for collecting, validating, and processing that data.

## Use cases
- format dates, numbers, currencies, and units per locale
- get translations of language and country names
- find plural rules for a language
- get locale-appropriate collation and sorting rules
- build internationalized software for many languages
- contribute translations for a language via the Survey Tool
- convert CLDR data to JSON for use in applications

## When to choose
- you need authoritative locale data for internationalization
- you are building i18n libraries or frameworks
- you want to contribute or curate translations for world languages

## When to avoid
- you need a ready-made i18n runtime library rather than raw data (use ICU or a CLDR-backed library)
- you need machine translation or NLP models
- you want a small, self-contained dataset without tooling

## Facets
- artifact type: dataset
- maturity: active
- function: internationalization, data-generation, developer-tools
- domain: developer-tools
- platform: cross-platform, jvm
- tags: locale-data, ldml, unicode, i18n, l10n, survey-tool, translation, localization, natural-language-processing, web-server
