The CLDR release this package was built from is recorded in `priv/localize/version`. ## What is used, and how The build pipeline in `data/` reads CLDR's XML and JSON releases together with the UCD tables in `priv/unicode/`, and compiles them into the Erlang term files under `priv/localize/`. Those files are the form in which Unicode data is distributed: * `priv/localize/locales/*.etf` — per-locale data: number, date, time, unit, currency, list and display-name formats, and plural rules. Only `en.etf` and `und.etf` are included in the Hex package; the remaining locales are downloaded at runtime from `https://elixir-localize.com/locales`, and are the same data in the same form. * `priv/localize/supplemental_data/`, `priv/localize/validity/` — CLDR supplemental and validity data: territory containment, likely subtags, language matching, unit conversions and preferences, currency definitions, time zone metadata and subtag validity. * `priv/localize/collation_table.etf` — collation weights derived from the CLDR root collation (`FractionalUCA.txt`), which is itself derived from the Unicode Collation Algorithm and the UCD. Code generated by `mix localize.unit.gen_conversions` embeds CLDR unit conversion factors as Elixir source, and so carries this notice too. The test data under `test/support/data/` includes cases taken from ICU's own test files, also published by Unicode, Inc. under the same license: `currency_amount_corpus.tsv` carries the currency parsing cases of ICU's `numberformattestspecification.txt` the currency name strings of ICU4C's `TestParseCurrencyInUCurr`, the currency round-trip tables of ICU4J's `NumberFormatTest.java` and ICU4C's `numfmtst.cpp`, and the plain decimal rows of CLDR's number test data (vendored as `decimal_*_test_data.tsv`), with Localize's expected results. Test data is not part of the Hex package. No Unicode data is modified in meaning. The pipeline reshapes it for efficient runtime access and discards fields Localize does not use. ## Notice The Unicode data is used under the Unicode License v3 (`SPDX-License-Identifier: Unicode-3.0`).
