# Description

# Root Zone Label Generation Rules for the Cyrillic Script

## Overview

This file contains Label Generation Rules (LGR) for the Cyrillic script for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for a Cyrillic Script Root Zone LGR” [Proposal-Cyrillic]. 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].

## Repertoire

According to Section 5, “Repertoire” in [Proposal-Cyrillic], the Cyrillic script LGR contains 86 single code points. One additional sequence, U+0455 U+0455 (ѕѕ) has been added in integration to facilitate cross-script variant mappings. (This addition does not change the possible labels under this LGR.)

The repertoire only includes code points used by languages that are actively written in the Cyrillic script. All languages with [EGIDS] level 1 through 4 were included. Level 5 languages were analyzed and included on a case by case basis. The repertoire is based on [MSR-5], which is a subset of [Unicode 11.0].

Code points outside the Cyrillic script that are listed in this file are targets for out-of-script variants and are identified by a reflexive (identity) variant of type “out-of-repertoire-var”. They do not form part of the repertoire.

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. For each repertoire element, one or more references document sufficient justification for inclusion in the repertoire; see “References” below. For code points that are part of the repertoire, comments identify the languages using it along with their [EGIDS] level.

## Variants

According to Section 6, “Variants” in [Proposal-Cyrillic], there are no variants defined within the Cyrillic script. However, integration with the Latin and Greek LGR does introduce some in-script variants due to cross-script variant transitivity.

In particular, the Cyrillic LGR inherits the following in-script variants as result of integration:

- Blocked: U+0456 (і) — U+0457 (ї).
- Blocked: U+0443 (у) — U+04AF (ү).

### Cross-script 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 among the closely related scripts Armenian, Cyrillic, Greek and Latin 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.

Where homoglyphs or near homoglyphs with Cyrillic code points exist in the Latin, Greek and Armenian scripts, out-of-repertoire variants are defined with a comment “Cross-script homoglyph”. As result of integration, including the effecs of cross-script transitivity, the number of cross-script variants listed for these scripts is larger than defined in Section 6, “Variants” in [Proposal-Cyrillic]. These are generally not marked.

Some cross-script variants originally defined in the proposal target code points that are not in the final repertoire of the Latin LGR. These mappings have been suppressed here.

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 labels 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].

### Redundant Sequence Defined for Integration

This LGR declares a cross-script variant between U+0073 (s) and U+0455 (ѕ). Therefore the sequence U+0073 U+0073 (ss) is automatically a variant to any sequence U+0455 U+0455 (ѕѕ) occurring in a Cyrillic label. Now the Latin LGR [RZ-LGR-Latin] declares an in-script variant between U+0073 U+0073 (ss) and U+00DF (ß). The Greek LGR [RZ-LGR-Greek] declares a variant between U+00DF (ß) and U+03B2 (β). Transitivity on the code point level requires these additional code points to be listed as variants to a sequence U+0455 U+0455 (ѕѕ) that would normally not need to be defined in the Cyrillic LGR because it is redundant: the LGR supports the repetition of the singleton code point U+0455 (ѕ) without restriction. As result of integration, the redundant sequence U+0455 U+0455 (ѕѕ) is added here, together with its variants in the Greek and Latin script. Being redundant other than in the definition of variants, it does not change the labels available under this LGR.

## Character Classes

The LGR does not define 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-5]. They are marked with ⍟.

### Cyrillic-specific Rules

This LGR does not define rules specific to Cyrillic.

## Methodology and Contributors

The Root Zone LGR for the Cyrillic script was developed by the Cyrillic Generation Panel. For methodology and contributors, see Sections 4 and 8 of [Proposal-Cyrillic], as well as [RZ-LGR-5-Overview]. After initial review by the Integration Panel, this LGR was deferred until it could be considered in the context of all related scripts. The LGR has been updated to reflect inherited variants resulting from integration.

Legend

Throughout this LGR, a code point sequence may be annotated with a string in ALL CAPS that is constructed on the same principle as a name for a Unicode Named Sequence. No claim is made that a sequence thus annotated is in fact a named sequence, nor that the annotation in such case actually corresponds to the formal name of a named sequence.

Code Point
  A code point or code point sequence.
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. Sequences are annotated with a set of all distinct script values.
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 “+”.
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. If present, the symbol ⍟ marks a default item shared among a set of LGRs.
✔ - core repertoire
  A check mark in the Part-of-repertoire column indicates a code point is part of the core repertoire.
✗ - out-of-repertoire
  A code point shown with ✗ is not part of the repertoire. It is listed only because it is the target of an out-of-repertoire-var variant mapping.

# Variant Sets

## Variant Set Summary

Number of variant sets | 31
Largest variant set | 13
Ordinary Variants by Type |
blocked | 302
Reflexive Variants by Type |
out-of-repertoire-var | 55

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.

A mapping where source and target are the same is reflexive. Variant sets consisting of only a single reflexive mapping are not shown as a set. Instead, the variant type of the mapping is listed in the Variants column of the Repertoire by Code Point table. Reflexive mappings that are part of a larger set are indicated with a “≡” and are counted once per entry.

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.
≡ - reflexive
  Indicates that Type, Ref and Comment are for a reflexive mapping where source equals target.
Type
  The type of the variant mapping, including predefined variant types such as “allocatable” and “blocked”; or any that are defined specifically for this LGR. A reflexive variant type “out-of-repertoire-var” designates the target as not part of the repertoire; it is required as target for one or more variant mappings that cross repertoire boundaries. In this LGR, types for variants between out-of-repertoire code points are shown in italic while types for pure in-repertoire variants are shown in bold.
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.

# Classes, Rules and Actions

## Character Classes

Implict defined by script tag | 4

The following table lists all named and implicit classes with their definition and a list of their members intersected with the current repertoire (for larger classes, this list is elided).

Name | Definition | Count | Members or Ranges | Ref | Comment
--- | --- | --- | --- | --- | ---
implicit | Tag=sc:Armn | 4 | {0561 0570 0582 0585} |  | Any character tagged as Armenian
implicit | Tag=sc:Cyrl | 86 | {0430-044F 0451-045C 045E-045F 0491 0493 0495 0497 0499 049B 049F 04A1 04A3 04A5 04A9 04AB 04AD 04AF 04B1 04B3 04B5 04B7 04BB 04BD 04BF 04CF 04D1 04D3 04D5 ...} |  | Any character tagged as Cyrillic
implicit | Tag=sc:Grek | 14 | {0390 03AC 03AF 03B1-03B3 03B9-03BA 03BF 03C1 03C4 03C6 03CA 03CC} |  | Any character tagged as Greek
implicit | Tag=sc:Latn | 36 | {0061 0063 0065 0068-006A 006C 006F-0070 0072-0073 0078-0079 00DF 00E1 00E4 00E6-00E7 00EB 00ED 00EF 00F3 00F6 00FF 0103 0127 0131 0155 01DD 024D 0259 0263 ...} |  | Any character tagged as Latin

Legend

Members or Ranges
  Lists the members of the class as code points (xxx) or as ranges of code points (xxx-yyy). Any class too numerous to list in full is elided with "...".
Tag=ttt
  A named or implicit class defined by all code points that share the given tag value (ttt).
Implicit
  An anonymous class implicitly defined based on tag value and for which there is no named equivalent.

## Whole label evaluation and context rules

Number of rules | 1
Used to trigger actions | 1

The following table lists all named rules defined in the LGR and indicates whether they are used as trigger in an action or as context (when or not-when) for a code point or variant.

Name | Regular Expression | Used as Trigger | Anchor | Used as Context | Ref | Comment
--- | --- | --- | --- | --- | --- | ---
leading-combining-mark | `(start)[∅=[[∅=\p{gc=Mn}] ∪ [∅=\p{gc=Mc}]]]` | ✔ |  |  |  | Default WLE rule matching labels with leading combining marks ⍟

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:
start or end
  (start) matches the start of the label; (end) matches the end of the label.
[\p{ }] - property
  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.

## 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.

# | Condition | Rule / Variant Set |  | Disposition | Ref | Comment
--- | --- | --- | --- | --- | --- | ---
1 | if label matches | leading-combining-mark | → | invalid |  | labels with leading combining marks are invalid ⍟
2 | if at least one variant is in | {out-of-repertoire-var} | → | invalid |  | any variant label with a code point out of repertoire is invalid ⍟
3 | if at least one variant is in | {blocked} | → | blocked |  | any variant label containing blocked variants is blocked ⍟
4 | if each variant is in | {allocatable} | → | allocatable |  | variant labels with all variants allocatable are allocatable ⍟
5 | if any label (catch-all) |  | → | valid |  | catch all (default action) ⍟

Legend

{...} - variant type set
  In the “Rule/Variant Set” column, the notation {...} means a set of variant types.
⍟ - default action
  Actions marked with ⍟ are included by default and may or may not be triggered by any possible label under this LGR.
