LOS ANGELES - The Internet Corporation for Assigned Names and Numbers (ICANN) has published the Root Zone Label Generation Rules Version 5 (RZ-LGR-5). Root Zone Label Generation Rules define a set of parameters that determine valid Internationalized Domain Name (IDN) labels and their variant labels for the root zone of the Domain Name System (DNS), a press release stated by ICANN.

ICANN script communities develop RZ-LGR proposals for different scripts or writing systems through the work of Generation Panels (GPs). These proposals, which cover 26 scripts, have now been integrated into the fifth version of RZ-LGR by the Integration Panel (IP) following a Public Comment period. This concludes the work of all active GPs.

ICANN org would like to thank all of the GPs for their efforts and years of hard work, and congratulate them on helping to enable the secure use of top-level domains (TLDs) in local languages and scripts. To learn more about GP work and building a more multilingual Internet, read this blog.

RZ-LGR-5 integrates the following scripts: Arabic, Armenian, Bangla, Chinese (Han), Cyrillic, Devanagari, Ethiopic, Georgian, Greek, Gujarati, Gurmukhi, Hebrew, Japanese (Hiragana, Katakana, and Kanji [Han]), Kannada, Khmer, Korean (Hangul and Hanja [Han]), Lao, Latin, Malayalam, Myanmar, Oriya, Sinhala, Tamil, Telugu, and Thai.

RZ-LGR development follows the Procedure to Develop and Maintain the Label Generation Rules for the Root Zone in Respect of IDNA Labels. A total of 28 scripts have been identified in the Maximal Starting Repertoire for inclusion in RZ-LGR. The remaining scripts will be included in future versions as proposals become available from the relevant GPs.
