Overview

This file contains a set of Label Generation Rules (LGR) for the Hebrew script for the Root Zone. For more details on this LGR, see "Proposal for Hebrew Script Root Zone LGR", Version 1.2, February 2019 [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-4]. The format of this file follows [RFC 7940].

Repertoire

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-4], which is a subset of [Unicode 6.3].

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 digits nor the HYPHEN-MINUS.

Each code point is tagged with the script or scripts that the code point is used with and one or more references documenting sufficient justification for inclusion in the repertoire; see "References" below. Comments provide additional information for some code points.

Variants

According to Section 6, "Variants", in "[Proposal-Hebrew]", this LGR defines five in-script variants, which are final forms of five in-script letters.

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].

Whole Label Evaluation (WLE) and Context Rules

Default Whole Label Evaluation Rules and Actions

The LGR includes the set of required default WLE rules and actions applicable to the Root Zone and defined in [MSR-4]. They are marked with ⍟.

Hebrew-specific Rules

According to Section 7, "Whole Label Evaluation (WLE) Rules" in [Proposal-Hebrew], the LGR does not define rules specific to the Hebrew script.

Methodology and Contributors

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-4-Overview].

[IL-IDN] was consulted during the work on this LGR.
