Purpose: ICANN has developed reference Internationalized Domain Name (IDN) tables in machine readable format, called Reference Label Generation Rules (LGRs) for the Second Level, to facilitate Pre-Delegation Testing (PDT) and the Registry Service Evaluation Process (RSEP) for the relevant gTLDs. At this time reference Japanese language LGR for the second level (XML, HTML) is being released for public comment for addition to this repository.
Current Status: Reference LGRs for the second level for 27 languages have been developed and published.
Next Steps: Based on the community input, the reference LGR for Japanese language will be finalized and will be added to this repository of reference LGRs for the second level for use during PDT and RSEP.
Section I: Description and Explanation
The reference LGRs are developed in the context of either a language or a script. These reference LGRs include a core set of code points, variant rules, and WLE rules that should be supported and also include an (optional) extended set serving special needs based on geographical or other variations.
A registry may use the relevant reference LGR to determine the set of code points and associated rules, or choose an appropriate subset, which best serves the needs of its end users. It may also deviate from these LGRs, by including additional code points and rules, motivated by the fact that registries would like to remain competitive by offering innovative solutions. The LGRs developed by the registry are evaluated as per procedures specified for the PDT and the RSEP.
The LGRs are developed for the languages prioritized on the basis of complexity and demand. Additional languages and scripts will be added later, as needed.
Section II: Background
The registries are generally encouraged to collaborate in defining common language-based or script-based IDN tables to allow for consistency for end users. The IDN tables used by each gTLD and some ccTLDs are posted at the IANA Repository for IDN Practices. During the New gTLD Program's Pre-Delegation Testing (PDT), ICANN has noted a large number of IDN table submissions. The reference LGRs have been developed to facilitate the review process. The process to develop these reference LGRs, as detailed in the Guidelines, ensures both linguistic and technical expert input with finalization based on community feedback through a formal public comment process. This work builds on the baseline IDN tables already being used in PDT. Reference LGRs for the second level for 27 languages have been published. Reference Japanese LGR for the second level has been revised after additional analysis, following the input received from the previous public comment.
