What We Need Your Input On:
Root Zone Label Generation Rules (RZ-LGR) are developed to define a conservative mechanism to determine valid Internationalized Domain Name (IDN) top-level domains (TLDs) and their variant labels. The successful development of Label Generation Rules depends on having community-based Generation Panels (GP) for each script that will be used in the root zone. The Latin Script GP has finalized the proposal for Latin Script Root Zone Label Generation Rules (Latin Script RZ-LGR). The proposal is being published for Public Comment before being finalized and submitted to the Integration Panel for integration into the Label Generation Rules for the Root Zone (RZ-LGR).

Background:
GP members are representatives from each of the communities that use a particular script or writing system and their role is to identify the valid characters, variants, and Whole Label Evaluation (WLE) rules for the given script or writing system. Each Generation Panel starts by considering the code points for the relevant script that are present in the Maximal Starting Repertoire (MSR) and based on these, develops a Label Generation Rules proposal to be used to generate TLD labels for that script. In doing so, they may need to coordinate efforts with other Generation Panels whenever their respective scripts are closely related. These proposals are then reviewed by the community through a Public Comment proceeding and then by an expert Integration Panel for approval and integration into the Label Generation Rules for the Root Zone (RZ-LGR). The details are defined in the LGR procedure.

Currently, there are multiple script communities that have formed Generation Panels and are actively working towards finalizing Label Generation Rules (LGRs) for the root zone including Japanese and Myanmar scripts. LGRs for the following 18 scripts have already been completed and integrated: Arabic, Bangla, Chinese, Devanagari, Ethiopic, Georgian, Gujarati, Gurmukhi, Hebrew, Kannada, Khmer, Lao, Malayalam, Oriya, Sinhala, Tamil, Telugu, and Thai. In addition, Armenian, Cyrillic, Greek, and Korean scripts have also been completed and are waiting to be integrated.

Next Steps:
Following the Public Comment proceeding and submission of the proposal by the Latin Script GP, which will reflect any changes due to community feedback, the Integration Panel will evaluate the proposal. If the proposal is successfully evaluated, it will be integrated into a subsequent version of the RZ-LGR. If not, the proposal will be sent back to the Latin Script GP with comments for further consideration and revision.
