Unicode Data

Localize embeds and redistributes data derived from the Unicode Common Locale Data Repository (CLDR) and the Unicode Character Database (UCD), both published by Unicode, Inc. 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). The following notice is reproduced verbatim, as that license requires.

bojanz/currency test data

test/support/data/currency_amount_corpus.tsv also carries the format and parse cases of the tests of bojanz/currency (formatter_test.go), read back as currency amounts with Localize's expected results. They are used under the MIT License. Test data is not part of the Hex package.

scrapinghub/price-parser test data

test/support/data/currency_amount_corpus.tsv also carries price strings from the tests of scrapinghub/price-parser (tests/test_price_parsing.py), each given a locale and Localize's expected result. They are used under the BSD 3-Clause License. Test data is not part of the Hex package.
