This file contains a set of Label Generation Rules (LGR) for the Hebrew script for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for a Hebrew Script Root Zone Label Generation Ruleset (LGR)”, Version 1.3 [Proposal-Hebrew]. This file is one of a set of LGR files that together form an integrated LGR for the DNS Root Zone [RZ-LGR-5]. The format of this file follows [RFC 7940].
According to Section 5, “Repertoire” in [Proposal-Hebrew], the Hebrew LGR contains 27 single code points, 5 of which are variants (final forms) of 5 others. The repertoire supports the Hebrew and Yiddish languages with restrictions appropriate for domain names. The repertoire is based on [MSR-5], which is a subset of [Unicode 11.0].
The Hebrew script is written from right to left. More details can be found in Section 3, “Background About the Script and Languages Using it” in [Proposal-Hebrew].
As part of the Root Zone, this LGR includes neither decimal digits nor the HYPHEN-MINUS.
Each code point is tagged with the script or scripts with which the code point is used, and one or more references documenting sufficient justification for inclusion in the repertoire; see “References” below. Comments provide additional information for some code points.
Code points outside the Hebrew script that are listed in this file are targets for out-of-repertoire variants and are identified by a reflexive (identity) variant of type “out-of-repertoire-var”. They do not form part of the repertoire.
According to Section 6, “Variants”, in [Proposal-Hebrew], this LGR defines five in-script variants, which are final forms of five in-script letters.
Additional Variants: This LGR inherits additional blocked cross-script variants by integration; they may not be listed here unless they result in in-script variants. However, for consistency, the variant mappings to ASCII code points are listed in full. See the merged, Common LGR [RZ-LGR-5] for details of all applicable cross-script variants, including any not listed here; always use the Common LGR for determining cross-script collisions of labels.
Variant Disposition: All variants are of type “blocked”, making labels that differ only by these variants mutually exclusive: whichever label containing either of these variants is chosen earlier would be delegated, while any other equivalent label should be blocked.
This LGR does not define allocatable variants.
The specification of variants in the Root Zone LGR follows the guidelines in [RFC 8228].
The LGR does not define character classes.
The LGR includes the set of required default WLE rules and actions applicable to the Root Zone and defined in [MSR-5]. They are marked with ⍟.
According to Section 7, “Whole Label Evaluation (WLE) Rules” in [Proposal-Hebrew], the LGR does not define rules specific to the Hebrew script.
The Root Zone LGR for the Hebrew script was developed by the Hebrew Generation Panel. For methodology and contributors, see Sections 4 and 8 in [Proposal-Hebrew], as well as [RZ-LGR-5-Overview].
[IL-IDN] was consulted during the work on this LGR.
As result of integration with additional scripts, this LGR has been updated. This update does not change the set of labels available under this LGR. For the prior version see [RZ-LGR-4-Hebr]. For consistency across RZ-LGRs, imposed variants to ASCII code points, but not to other scripts, are now explicitly listed. Additional cross-script variants for this script exist and are defined in [RZ-LGR-5].
