LOS ANGELES - The ICANN organization (org) updated the Label Generation Rules (LGR) Toolset, providing functionality for checking conformance with IDNA2008 in addition to existing functions for validating a label, generating variant labels, managing LGRs, and reviewing Internationalized Domain Name (IDN) Tables, according to the official website of ICANN.
The LGR Toolset assists end users in validating IDN labels and determining their variant labels and brings consistency and transparency to the IDN Table review process for registry operators.
To use the LGR Toolset, please visit the LGR Toolset webpage. The toolset includes three modes:
Validate Label(s) Mode: In this mode, the tool validates the label(s) and generates the variant label(s) according to the selected reference data. The available reference data are Reference LGRs for the Second Level and Root Zone LGRs. The user manual for this mode is available here.
Advanced LGR Mode: Users can create, view, and manage LGRs in this mode. The tool can merge multiple LGRs and determine cross-script variants of the labels using a merged LGR. Users can upload a list of labels to validate and generate variant labels based on the user's developed LGR. The user manual for this mode is available here.
Review IDN Table(s) Mode: The tool compares IDN tables with the Reference LGRs for the second level, or with Root Zone Label Generation Rules (RZ-LGR) where the Reference LGRs are not yet available. Now the tool also provides the option to compare the IDN table(s) against the explicit requirements in the IDNA2008 standard (RFC5890, RFC5891, RFC5892, and RFC5893). The user manual for this mode is available here.
The tool has a Label Form function, which generates the A-label, U-label, and code points of the input label(s) if they comply with the IDNA2008 standard.
