Description

Label Generation Rules for the Root Zone — LGR-1

Overview

This document, together with the set of element LGRs, specifies 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].

Element LGRs

The Label Generation Rules for the Root Zone (LGR-1) are integrated from the following set of script-specific element LGRs:

Each element LGR represents in full the underlying, proposed script-based LGR, except for changes required by the integration process or for uniformity of presentation. See Section 3, "Integration" in [LGR-1].

Merged LGR

This merged LGR contains the Union of the repertoire, variant mappings and Whole Label Evaluation (WLE) rules as described in the following sections. Data that are necessarily script-dependent, such as the type for variant mappings have been removed or replaced by default values.

When processing an applied for label, the integrated LGR presents the complete data and specification needed for conflict checking with any existing label, independent of script, while each script-specific element LGRs presents the complete data and specification to determine the validity and full set of allocatable variants for the label, when applied for under that script.

Repertoire

The repertoire of the integrated Root Zone LGR is the cumulative repertoire of all the Element LGRs that have been integrated into this version. Those repertoires, in turn were developed based on [MSR-2], which is a subset of Unicode 6.3 [Unicode 6.3].

As a Root Zone LGR, the repertoire includes neither digits nor the HYPHEN-MINUS.

For further details, see Section 3.1.1, in [LGR-1].

Each code point or range is tagged with the script or scripts that the code point is used with, and a reference to the Unicode Standard in which the code point was first encoded, see "References" below.

Variants

The variant mappings in this LGR are the union of the variant mappings from all the Element LGRs that have been integrated into this version of the Root Zone LGR. Because the disposition of variant labels, for example as "allocatable", is specific to each script, they cannot be expressed in the script-neutral context of this integrated LGR. Instead. all variant mappings are labeled as "blocked" in this document as needed for conflict checking. See also Section 3.1.2 in [LGR-1].

Whole Label Evaluations Rules

The integrated LGR includes the cumulative set of Whole Label Evaluation rules for all Element LGRs that have been integrated into this version. See Section 3.1.3, in [LGR-1]. See also the comments given for each rule or action.

Default Whole Label Evaluation Rules

The integrated 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 Root Zone Label Generation Rules - LGR-1 [LGR-1] were integrated by the Integration Panel [IP], from a set of proposals for script-based root zone LGRs developed by community-based Generation Panels [GPS] in an open process with multiple public consultations defined in [Procedure] and [Guidelines]. For more information on the methodology and contributors see [LGR-1].

In the listing of the repertoire, references starting at [0] refer to Unicode Standard versions in which the corresponding code points were initially encoded. References [100] and above correspond to the script-specific LGRs that include the repertoire item. Repertoire items may have more than one reference.

Repertoire by Code Point

The following table lists the repertoire by code point (or code point sequence). The data in the Script and Name column are extracted from the Unicode character database. Where the comment in the original LGR is equal to the character name, it has been suppressed.

For any code point or sequence for which a variant is defined, the link to the associated variant set, or if mapped to itself, the variant type of that mapping is provided in the Variants column.

Legend

Code Point
A code point or code point sequence.
Name
Shows the character or sequence name from the Unicode Character Database.
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.
References
Links to the references associated with the code point or sequence, if any.
Variants
A 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
If the comment in this row consists only of the code point or sequence name it is suppressed in this view.

Variant Sets

Summary

Number of variant sets 16
Largest variant set 8
Ordinary Variants by Type blocked (192)
Reflexive Variants by Type  

The following tables list each pair of variant mappings on one row. For each pair of code points, by convention, the lower code point is taken as the source of the mapping in the forward → direction and the reverse direction ← is not listed separately. The variant mappings defined in an LGR are required to be symmetric, that is, both the forward and reverse mappings must be specified.

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 “≡”.

Where the type of both forward and reverse mappings are the same, a single value is given in the Type(s) column, otherwise the types for forward and reverse mapping are given in that order, as indicated by the arrows. The same applies to any comments.

In a properly specified LGR, all members of each variant set are variants of each other, a property called transitivity. Because of that, all variant sets are necessarily disjoint. In each set, shading is used to group mappings from the same source code point or sequence.

Members or Ranges
Lists the members of the class as code points (xxx) or ranges of code points (xxx-yyy). Any class too numerous to list in full is elided with "...".
Tag=ttt
A named class is defined by all code points that share the given tag value (ttt).
Implicit
An anonymous class implicitly defined class based on tag value.

Whole label evaluation and context rules

The following table lists all the top-level, or 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. (Any use of context rules for variants is not indicated).

Legend

Regular Expression
A regular expression equivalent to the rule, shown in the standard notation with some extensions as noted.
[\p{ }] - property character set
A character set defined by reference to a value for a given Unicode property [\p{prop=val}]. A set defined via "\P" indicates the set complement.
[&&,-,^] - set operators
Sets may be combined by set operators (&& = intersection, - = difference, ^ = symmetric difference) or concatenated (union).
∅= - empty set
Indicates that the following set is empty because of the result of set operations, or because none of its elements are part of the repertoire defined here.An empty set that is not optional means that a rule can never match.
⍟ - default rule
Default WLE Rules are marked with ⍟.

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 label matches no-mix-teh-marbuta-goal → invalid [100] do not mix Arabic letters TEH MARBUTA and FEH WITH DOT MOVED BELOW in the same label
4 if label matches no-mix-feh-with-dot-moved-below → invalid [100] do not mix Arabic letters FEH and FEH WITH DOT MOVED BELOW in the same label
5 if label matches no-mix-feh-qaf-with-dot-above → invalid [100] do not mix Arabic letters FEH and QAF WITH DOT ABOVE in the same label
6 if label matches no-mix-qaf-with-dot-above → invalid [100] do not mix Arabic letters QAF and QAF WITH DOT ABOVE in the same label
7 if label matches no-mix-kaf-keheh → invalid [100] do not mix Arabic letters KAF and KEHEH in the same label
8 if label matches no-mix-kaf-swash → invalid [100] do not mix Arabic letters KAF and SWASH KAF in the same label
9 if label matches no-mix-heh-doachashmee → invalid [100] do not mix Arabic letters HEH and HEH DOACHASHMEE in the same label
10 if label matches no-mix-heh-goal → invalid [100] do not mix Arabic letters HEH and HEH GOAL in the same label
11 if label matches no-mix-heh-ae → invalid [100] do not mix Arabic letters HEH and AE in the same label
12 if label matches no-mix-alef-maksura-farsi-yeh → invalid [100] do not mix Arabic letters ALEF MAKSURA and FARSI YEH in the same label
13 if label matches no-mix-peh-noon-with-three-dots-above → invalid [100] do not mix Arabic letters PEH and NOON WITH THREE DOTS ABOVE in the same label
14 if label matches no-mix-kaf-with-ring-gaf → invalid [100] do not mix Arabic letters KAF WITH RING and GAF in the same label
15 if label matches no-mix-kaf-with-ring-keheh-with-three-dots-above → invalid [100] do not mix Arabic letters KAF WITH RING and KEHEH WITH THREE DOTS ABOVE
16 if label matches no-mix-gaf-keheh-with-three-dots-above → invalid [100] do not mix Arabic letters GAF and KEHEH WITH THREE DOTS ABOVE in the same label
17 if label matches no-mix-noon-with-three-dots-above-yeh-with-three-dots-below → invalid [100] do not mix Arabic letters NOON WITH THREE DOTS ABOVE and YEH WITH THREE DOTS BELOW in the same label
18 if label matches no-mix-heh-goal-ae → invalid [100] do not mix Arabic letters HEH GOAL and AE in the same label
19 if at least one variant is in {blocked} → blocked   variant labels containing blocked variants are blocked ⍟
20 if each variant is in {allocatable} → allocatable   variant labels with all variants allocatable are allocatable ⍟
21 if any label (catch-all)   → valid   catch all (default action) ⍟

In the Rule or Variant Set column the notation {...} means a set of variant types, ⍟ marks a default action.

Note: The following variant types are used in one or more actions, but are not defined in this LGR: out-of-repertoire-var, allocatable. This is not necessarily an error.
