ICANN Publishes Two 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 Unified Canadian Aboriginal Syllabics script and the Javanese script, as well as updated seven other LGRs, based on community proposals and input.

Second-Level Reference LGRs provide rules for forming valid domain name labels in different languages and scripts and for identifying 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 working groups for the respective scripts and using other relevant information, such as Root Zone Label Generation Rules where available. They were finalized following a Public Comment proceeding, incorporating the feedback received.

In addition, the following Second-Level Reference LGRs have been updated: Arabic script, Arabic language, Inuktitut language, Japanese language, Japanese script, Latin script, and Latin script (Full Variant Set). Details of these updates are available in the description of each LGR.

In total, ICANN has published Second-Level Reference LGRs covering 30 scripts and 32 languages.

  • 30 Scripts: Arabic, Armenian, Balinese, Bangla (Bengali), Chinese, Cyrillic, Devanagari, Ethiopic, Georgian, Greek, Gujarati, Gurmukhi, Hebrew, Japanese (Hiragana, Katakana, Kanji [Han]), Javanese, Kannada, Khmer, Korean (Hangul, Hanja [Han]), Lao, Latin, Malayalam, Myanmar, Oriya, Sinhala, Tamil, Telugu, Thaana, Thai, and Unified Canadian Aboriginal Syllabics.

  • 32 Languages: 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.

If you have any questions or feedback regarding these LGRs, please send an email to [email protected].
