To improve the transparency and consistency of the Internationalized Domain Name (IDN) table review process and facilitate the registry operations of new gTLDs, ICANN has developed four additional reference IDN tables in machine-readable format, called reference Label Generation Rulesets (LGRs) for the second level. Arabic, Hebrew, and Sinhala script-based LGRs, and the Hebrew language-based LGR, are included in this release. The reference IDN tables are based on the Guidelines for Developing Reference Label Generation Rules (LGRs), which were finalized after community review. These will be used in reviewing IDN tables submitted by gTLD registries, e.g., through the Registry Service Evaluation Policy (RSEP) process.
