Description

Root Zone Label Generation Ruleset for the Arabic Script

Overview

This document specifies an element LGR for a specific script that forms part of an integrated set of Label Generation Rules for the Root Zone. For more details on the Root Zone LGR and their development see "Root Zone Label Generation Rules - LGR-1: Overview and Summary", Integration Panel, 24 February 2016 [LGR-1].

For more details on this element LGR and its development see TF-AIDN, "Proposal for Arabic Script Root Zone LGR", Version 3.4, 2015 November 18 [Proposal].

Repertoire

The repertoire for this element LGR for the Arabic script is based on Section 3.2 in [Proposal] and only includes code points used by languages that are actively written in the Arabic script. It excludes code points for which TF-AIDN was unable to find sufficient evidence of use (see Appendix F in [Proposal]). The repertoire is based on [MSR-2], which is a subset of Unicode 6.3 [Unicode 6.3].

Read the rest of the description Show less

This LGR does not include combining marks or code point sequences. All combining marks have been excluded for these reasons:

  • First, they can significantly overproduce and would require additional rules to contain them effectively, complicating the design.

  • Second, even where they are required for some languages, they are optional for others.

  • Third, this also circumvents the issue raised by [IAB].

As part of the Root Zone, this LGR includes neither digits nor the HYPHEN-MINUS.

For further details, see Section 3.2 "Code point repertoire included", in [Proposal].

Each code point or range 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.

Variants

This LGR includes "blocked" and "allocatable" variants, assigned according to Section 4 "Final recommendation of variants for Top Level Domains (TLDs)" in [Proposal]. These recommendations balance the desire to minimize the number of possible allocatable variants with the need to keep the definition of variants simple. See also the comments given in the listing.

Whole Label Evaluations Rules

This LGR includes Whole Label Evaluation rules specific to the Arabic script. See Section 5 "Whole Label Evaluation (WLE) rules", in [Proposal]. As specified, the rules serve to prevent the mixing of two variants of the same code point within the same label. This has the effect of reducing overproduction of variant labels. See also the comments given for each rule or action.

Default Whole Label Evaluation Rules

The LGR includes the set of required default WLE rules and actions applicable to the Root Zone and defined in [MSR-2]. They are marked with ⍟.

Methodology and Contributors

The proposal for an Arabic Script Root Zone LGR [Proposal] that this LGR is based on, was developed by the Task Force for Arabic Script IDNs [TF-AIDN], based on multiple open public consultations.

For more information and for methodology and contributors see [Proposal].

Variants

Code points grouped into sets of mutual variants. Every member of a set produces the same set of variant labels, so a registration of one has implications for all the others. Sets of a single member are omitted, as are the identity mappings RFC 7940 requires each member to declare.

List
16 variant sets, containing 192 variants.

Rules

Conditions evaluated against a whole label, or against the context around a single code point. The notation borrows from regular expressions: ^ and $ anchor to the start and end of a label, . matches any code point, (?= ) and (?<= ) look ahead and behind, and * and + repeat. Two symbols are specific to rulesets: ◆ is the code point being tested, and ⟨name⟩ refers to another rule.
