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:

  • Root Zone Label Generation Ruleset for the Arabic Script [100]

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.

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.
