Description

Root Zone Label Generation Rules for the Gurmukhi Script

Overview

This file contains Label Generation Rules (LGR) for the Gurmukhi script for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for a Gurmukhi Script Root Zone Label Generation Ruleset (LGR)” [Proposal-Gurmukhi]. 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-Gurmukhi], the Gurmukhi script LGR contains 56 single code points. This Repertoire covers the Punjabi language written using the Gurmukhi script. Punjabi ([EGIDS] level 2) is the only language currently using the Gurmukhi script.

The repertoire is based on [MSR-5], which is a subset of [Unicode 11.0].

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

Code points outside the Gurmukhi 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.

Each code point is tagged with the script or scripts with which the code point is used, one or more other character categories, and one or more references documenting sufficient justification for inclusion in the repertoire; see “References” below. For code points that are part of the repertoire, comments identify the language using the code point, as well as alternate names of some code points.

Variants

The Gurmukhi and Devanagari scripts are closely related to each other and there are many code points in both scripts which can be confused with code points in the other script. Five sequences of Devanagari code points are defined as variants of single Gurmukhi code points. Additional cross-script variant analysis identified a smaller set of code points from the Bengali script. Where these can cause confusion even to a careful observer, they have been defined as variants. Variants due to transitivity among cross-script variants are not marked.

There are no in-script variants defined for Gurmukhi. See Section 6, “Variants”, in [Proposal-Gurmukhi].

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 variant 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].

Character Classes

Gurmukhi is an alphasyllabary and the heart of the writing system is the Akshar. This is the unit which is instinctively recognized by users of the script. The elements of the writing system consist of Consonants, Implicit Vowel Killer: Halant, Vowels, Bindi, Tippi, Addak, Nukta and Visarga.

Consonants: Gurmukhi consonants contain an implicit vowel schwa /ə/. They are also used without any modification to represent consonant sounds without an implicit /ə/ vowel More details in Section 3.3.1, “The Consonants” in [Proposal-Gurmukhi].

Virama: Unlike the Halant in other Neo-Brahmi scripts, U+094D ( ् ) GURMUKHI SIGN VIRAMA is not used in general to strip a consonant letter’s implicit vowel. The Virama is only used to create a conjunct where the letter U+0A39 HA, U+0A30 RA or U+0A35 VA is the second element in a conjunct. More details in Section 3.3.2, “The Implicit Vowel Killer: Virama” in [Proposal-Gurmukhi].

Vowels and Matras: Punjabi has seven long vowels and three short vowels (ਅ /ə/, ਇ /I/, and ਉ /U/) . Each of them, except U+0A05 have a corresponding vowel sign, or matra, which is used to modify the vowel inherent in the preceding consonant. More details in Section 3.3.3, “Vowels” in [Proposal-Gurmukhi].

Bindi: Bindi represents a homo-organic nasal. Bindi is used with all long vowels and the short vowel U+0A09, as well as with the matras of long vowels, except the matra U+0A42. More details in Section 3.3.4.1, “The Bindi” in [Proposal-Gurmukhi].

Tippi: Tippi is used to nasalize short vowels /ə/ and /I/ at all places, as well as /U/ and /u/ after a consonant. Therefore, Tippi comes after consonants without a vowel sign (representing the matra of /ə/ “mukta” ) and after the matra of /I/ ( ਿ ) following vowel carriers and consonants, such as in ਸੰ and ਸਿੰ. The matras of /U/ ( ੁ,) and /u/ ( ੂ ) following a consonant also take a Tippi. In addition, Tippi is used in gemination for nasal consonants ਙ, ਞ, ਨ and ਮ. More details in Section 3.3.4.2, “The Tippi” in [Proposal-Gurmukhi].

Addak: Addak is used to mark the gemination of the following consonant. In Punjabi, addak usually can follow mukta, aunkar ( ੁ ) and sihari ( ਿ ), and the vowel signs of the short vowels /ə/, /u/ and /i/. It geminates the consonant that follows it; therefore it cannot occur at the end of a label. More details in Section 3.3.4.3 “The Addak” in [Proposal-Gurmukhi].

Nukta: Called pairin bindi in Punjabi, Nukta is used with the six consonants (ਸ, ਖ, ਗ, ਜ, ਫ and ਲ ) defined as set C1 to represent the phonemes of words of Sanskrit and Perso-Arabic sources. More details in Section 3.3.4.4, “Nukta” in [Proposal-Gurmukhi].

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 ⍟. The default prohibition on leading combining marks is equivalent to ensuring that a label only starts with a consonant or vowel.

Gurmukhi-specific Rules

These rules have been drafted to ensure that the prospective Gurmukhi label conforms to akshar formation norms as desired in Gurmukhi script. These norms are exclusively presented as context rules.

The following symbols are used in the WLE rules:
C → Consonant
M → Matra
V → Vowel
B → Bindi
D → Tippi
A → Addak
H → Virama / Halant
N → Nukta
M1 → { ਿ(U+0A3F), ੁ (U+0A41) } (Short matras)
M2 → M - M1 (Long matras)
V1 → { ਅ (U+0A05), ਇ (U+0A07), ਉ (U+0A09)} (Short Vowels)
V2 → V - V1 (Long Vowel)
C1 → {ਖ (U+0A16), ਗ (U+0A17), ਜ (U+0A1C), ਫ (U+0A2B), ਲ (U+0A32), ਸ (U+0A38)}
C2 → { ਰ (U+0A30), ਵ (U+0A35), ਹ (U+0A39)}
C3 → C – {ਙ (U+0A19), ਞ (U+0A1E), ਣ (U+0A23), ਹ (U+0A39), ੜ (U+0A5C)}

The rules are:

  • 7.1 N: must be preceded by C1
  • 7.2 H: must be preceded by C or N and followed by C2
  • 7.3 M: must be preceded by C or N
  • 7.4 B: must be preceded by specific V or M
  • 7.5 D: must be preceded by C, N or specific V or M
  • 7.6 A: must be preceded by C, N or specific V or M and followed by C3

More details in Section 7, “Whole Label Evaluation Rules (WLE)” in [Proposal-Gurmukhi].

Methodology and Contributors

The Root Zone LGR for the Gurmukhi script was developed by the Neo-Brahmi Generation Panel (NBGP) the members of which have experience in linguistics and computational linguistics in a wide variety of languages written with Neo-Brahmi scripts. Under the Neo-Brahmi Generation Panel, there are nine scripts belonging to separate Unicode blocks. Each of these scripts has been assigned a separate LGR, with the Neo-Brahmi GP ensuring that the fundamental philosophy behind building those LGRs are in sync with all other Brahmi-derived scripts. For further details on methodology and contributors, see Sections 4 and 8 in [Proposal-Gurmukhi], as well as [RZ-LGR-5-Overview].

Identity mappings, where a code point is declared a variant of itself, are required by RFC 7940 and are omitted here. 106 variant records are declared in total.

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
25 variant sets, containing 76 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.

Actions

Actions are evaluated in the order shown. The first action whose conditions match determines the disposition of the label.

# Disposition Conditions
1 invalid label matches leading-combining-mark labels with leading combining marks are invalid MSR default
2 invalid any variant is out-of-repertoire-var any variant label with a code point out of repertoire is invalid MSR default
3 blocked any variant is blocked any variant label containing blocked variants is blocked MSR default
4 allocatable all variants are allocatable variant labels with all variants allocatable are allocatable MSR default
5 valid any label default catch all (default action) MSR default
