# Root Zone Label Generation Rules for the Arabic Script

## Overview

This file contains a set of Label Generation Rules (LGR) for Arabic for the Root Zone. For more details on this LGR and its development, see TF-AIDN, "Proposal for Arabic Script Root Zone LGR", Version 3.4, 18 November 2015 [Proposal]. This file is one of a set of LGR files that together form an integrated LGR for the DNS Root Zone [RZ-LGR-3]. The format of this file follows [RFC 7940].

## Repertoire

The repertoire is described in Section 3.2 of [Proposal] and only includes the 128 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-4], which is a subset of [Unicode 6.3].

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 regarding duplication between some precomposed code points and combining sequences 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. Comments identify the languages using the code point.

## 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.

The specification of variants in the Root Zone LGR follows the guidelines in [RFC 8228].

## Character Classes

This proposal does not define named character classes.

## 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 ⍟.

### Arabic-specific Rules and Actions

This LGR includes WLE rules and actions specific to the Arabic script. See Section 5 "Whole Label Evaluation (WLE) rules", in [Proposal]. As specified, the rules and actions serve to prevent the mixing of two variants of the same code point within the same label. This reduces overproduction of variant labels. The rules are listed here with the numbers given in Table 17 in [Proposal]. See also the comments given for each rule or action.

- no-mix-kaf-keheh — WLE Rule 1: do not mix Arabic letters KAF and KEHEH in the same label
- no-mix-kaf-swash — WLE Rule 2: do not mix Arabic letters KAF and SWASH KAF in the same label
- no-mix-alef-maksura-farsi-yeh — WLE Rule 3: do not mix Arabic letters ALEF MAKSURA and FARSI YEH in the same label
- no-mix-heh-goal — WLE Rule 4: do not mix Arabic letters HEH and HEH GOAL in the same label
- no-mix-heh-goal-ae — WLE Rule 5: do not mix Arabic letters HEH GOAL and AE in the same label
- no-mix-heh-ae — WLE Rule 6: do not mix Arabic letters HEH and AE in the same label
- no-mix-heh-doachashmee — WLE Rule 7: do not mix Arabic letters HEH and HEH DOACHASHMEE in the same label
- no-mix-teh-marbuta-goal — WLE Rule 8: do not mix Arabic letters TEH MARBUTA and FEH WITH DOT MOVED BELOW in the same label
- no-mix-noon-with-three-dots-above-yeh-with-three-dots-below — WLE Rule 9: do not mix Arabic letters NOON WITH THREE DOTS ABOVE and YEH WITH THREE DOTS BELOW in the same label
- no-mix-peh-noon-with-three-dots-above — WLE Rule 10: do not mix Arabic letters PEH and NOON WITH THREE DOTS ABOVE in the same label
- no-mix-feh-with-dot-moved-below — WLE Rule 11:do not mix Arabic letters FEH and FEH WITH DOT MOVED BELOW in the same label
- no-mix-qaf-with-dot-above — WLE Rule 12: do not mix Arabic letters QAF and QAF WITH DOT ABOVE in the same label
- no-mix-feh-qaf-with-dot-above — WLE Rule 13: do not mix Arabic letters FEH and QAF WITH DOT ABOVE in the same label
- no-mix-kaf-with-ring-gaf — WLE Rule 14: do not mix Arabic letters KAF WITH RING and GAF in the same label
- no-mix-kaf-with-ring-keheh-with-three-dots-above — WLE Rule 15: do not mix Arabic letters KAF WITH RING and KEHEH WITH THREE DOTS ABOVE
- no-mix-gaf-keheh-with-three-dots-above — WLE Rule 16: do not mix Arabic letters GAF and KEHEH WITH THREE DOTS ABOVE in the same label

## 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], as well as [RZ-LGR-3-Overview].

Legend

Code Point
  A code point or code point sequence.
Name
  Shows the character or sequence name from the Unicode Character Database. Named sequences are listed with their normative names, for ad-hoc sequences the individual names are shown separated by “+”.
Glyph
  The shape displayed depends on the fonts available to your browser.
Script
  Shows the script property value from the Unicode Character Database. Combining marks may have the value Inherited and code points used with more than one script may have the value Common.
Ref
  Links to the references associated with the code point or sequence, if any.
Variants
  Link to the variant set the code point or sequence is a member of, except where a coded point or sequence maps only to itself, in which case the type of that mapping is listed.
Comment
  The comment as given in the XML file. However, if the comment for this row consists only of the code point or sequence name, it is suppressed in this view. By convention, comments starting with “=” denote an alias.

# 3 Variant Sets

## Variant Set Summary

Number of variant sets | 16
Largest variant set | 8
Variants by Type |
allocatable | 26
blocked | 166

The following tables list all variant sets defined in this LGR, except for singleton sets. Each table lists all variant mapping pairs of the set; one per row. Mappings are assumed to be symmetric: each row documents both forward (→) and reverse (←) mapping directions. In each table, the mappings are sorted by Source value in ascending code point order; shading is used to group mappings from the same source code point or sequence.

Where the type of both forward and reverse mappings are the same, a single value is given in the Type column, otherwise the types for forward and reverse mappings, as well as comments and references are listed above one another. For summary counts, both forward and reverse mappings are always counted separately.

In any LGR with variant specifications that are well behaved, all members within each variant set are defined as variants of each other; the mappings in each set are symmetric and transitive; and all variant sets are disjoint.

Common Legend

Source
  By convention, the smaller of the two code points in a variant mapping pair.
Target
  By convention, the larger of the two code points in a variant mapping pair.
Glyph
  The shape displayed for source or target depends on the fonts available to your browser.
→ - forward
  Indicates that Type, Ref and Comment apply to the mapping from source to target.
← - reverse
  Indicates that Type, Ref and Comment apply to the reverse mapping from target to source.
↔ - both
  Indicates that Type, Ref and Comment apply to both forward and reverse mapping.
Type
  The type of the variant mapping. There are some predefined variant types such as “allocatable” and “blocked”, while others are defined specifically for each LGR.
Ref
  One or more reference IDs (optional). A “/” separates references for reverse / forward mappings, if different.
Comment
  A descriptive comment (optional). A “/” separates comments for reverse / forward mappings, if different.

Legend

Used as Trigger
  This rule triggers one of the actions listed below.
Used as Context
  This rule defines a required or prohibited context for a code point C or variant V.
Anchor
  This rule has a placeholder for the code point for which it is evaluated.
Regular Expression
  A regular expression equivalent to the rule, shown in a modified notation as noted:
(... | ...) - choice
  When there is more than one alternative in a rule, the choices are separated by the alternation operator (...|...).
start or end
  (start) matches the start of the label; (end) matches the end of the label.
. - any code point
  . matches any code point.
*, +, ?, {n,m} - count operators
  * indicates 0 or more, + indicates one or more, and ? indicates up to one instance. {n,m} indicates at least n and at most m instances.
[\p{ }] - property character set
  Set of all characters matching a given value for a Unicode property [\p{prop=val}]. Note: uppercase “\P” defines the complement of a property set.
∪, ∩, ∖, ∆ - set operators
  Sets may be combined by set operators (∪ = union, ∩ = intersection, ∖ = difference, ∆ = symmetric difference).
∅= - empty set
  Indicates that the following set is empty because of the result of set operations, or because none of its elements is part of the repertoire defined here. A rule with a non-optional empty set never matches.
⍟ - default rule
  Rules marked with ⍟ are included by default and may or may not be triggered by any possible label under this LGR.

## 4.3 Actions

The following table lists the actions that are used to assign dispositions to labels and variant labels based on the specified conditions. The order of actions defines their precedence: the first action triggered by a label is the one defining its disposition.
