ICANN Publishes Three Additional Second-Level Reference Label Generation Rules

The Internet Corporation for Assigned Names and Numbers (ICANN) has published Second-Level Reference Label Generation Rules (LGRs) for the Balinese script, the Thaana script, and the Inuktitut language. ICANN has also updated two other LGRs.

Second-Level Reference LGRs provide the rules to form valid domain name labels in different languages and scripts and to identify their variant labels. They are published to improve the transparency and consistency of the Internationalized Domain Name table review process and to facilitate registry operations.

The Second-Level Reference LGRs were developed in consultation with the community panels for the respective script and using other relevant information, e.g., Root Zone Label Generation Rules where available. They were finalized after a Public Comment proceeding.

The existing Myanmar script (full variant set) and the Spanish language Second-Level Reference LGRs have also been updated.

In total, 27 script-based and 32 language-based Reference LGRs have now been published:

• 27 Script-Based LGRs: Arabic, Armenian, Balinese, Bangla (Bengali), Chinese, Cyrillic, Devanagari, Ethiopic, Georgian, Greek, Gujarati, Gurmukhi, Hebrew, Japanese (Hiragana, Katakana, Kanji [Han]), Kannada, Khmer, Korean (Hangul, Hanja [Han]), Lao, Latin, Malayalam, Myanmar, Oriya, Sinhala, Tamil, Telugu, Thaana, and Thai.
• 32 Language-Based LGRs: Arabic, Belarusian, Bosnian (Cyrillic), Bosnian (Latin), Bulgarian, Chinese, Danish, English, Finnish, French, German, Hebrew, Hindi, Hungarian, Icelandic, Inuktitut, Italian, Japanese, Korean, Latvian, Lithuanian, Macedonian, Montenegrin, Norwegian, Polish, Portuguese, Russian, Serbian, Spanish, Swedish, Thai, and Ukrainian.

Additional languages and scripts will be included in future releases as relevant community input becomes available.
