Third Version of Label Generation Rules Released

ICANN announced the release of the third version of Label Generation Rules for the Root Zone (RZ-LGR-3). These define a set of criteria for determining valid Internationalized Domain Name (IDN) labels. The IDN Labels are for the Root Zone of the Domain Name System (DNS) and their variant labels.

16 out of the 28 scripts have been identified in the Maximal Starting Repertoire. They are now integrated in the Label Generation Rules for the Root Zone (RZ-LGR). The first version (RZ-LGR-1), released in March 2016, integrated the Arabic script. The second version (RZ-LGR-2), released in August 2017, integrated five more scripts, including Ethiopic, Georgian, Khmer, Lao and Thai. RZ-LGR-3 integrates many more scripts like Devanagari, Gujarati and a few more. They have completed Armenian and Cyrillic script proposals. However, they are deferred from integration until related script proposals are also finalized. The future releases of RZ-LGR will include the remaining proposals.

The Generation Panels have defined the label generation rules.  The Integration Panel evaluates and integrates it.  This is done after the public comment period. However, the Procedure to Develop and Maintain the Label Generation Rules for the Root Zone in Respect of IDNA Labels follows it.
