Reference Label Generation Rules for the Inuktitut Language

Overview

This document specifies a set of Label Generation Rules (LGR) for Inuktitut language in Québec and Canada using a Syllabic Script known as CANS or UCAS (Unified Canadian Aboriginal Syllabics) for the second level domain. The format of this file follows [RFC 7940].

This LGR is designed to be used in a zone that does cater to French IDNs. This LGR includes features that support its use in context of a French LGR in the same zone. 

For details and additional background on the Inuktitut language, see "Inuktitut Language Reference Label Generation Rules for Second-Level Domain Names" [Proposal-Inuktitut].

Repertoire

The repertoire for the Inuktitut Syllabic script (Unified Canadian Unified Syllabics) contains 151 syllabics characters and combining diacritical marks as defined in Section 5.1 “Included Code Points” in [Proposal-Inuktitut].

For the second level, the repertoire has been augmented with the ASCII digits, U+0030 to U+0039, plus U+002D HYPHEN-MINUS, for a total of 162 repertoire elements.

Any code points outside the Inuktitut Language repertoire that are targets for out-of-repertoire variants would be included here only if the variant is listed in this file. In this case they are identified as a reflexive (identity) variant of type “out-of-repertoire-var”. Whether or not they are listed, they do not form part of the repertoire.

Repertoire Listing: Each code point or range is tagged with the script or scripts with which the code point is used and one or more other character categories. For each repertoire element, one or more references document sufficient justification for inclusion in the repertoire; see the “References” below. For code points that are part of the repertoire, comments identify the languages using the code point along with their [EGIDS] level.

Excluded Characters

The following code points associated to the Inuktitut Syllabics in the UNICODE UCAS table have been excluded in the actual Inuktitut LGR repertoire due to the fact that those code points have never been used, or have not been used in recent times.

Variants

A number of letters bear strong similarity to Latin letters, these have been given cross-script variant mappings.

Digit Variants: All Canadian Aboriginal digits are treated as semantic variants of the corresponding common (ASCII) digits. By transitivity, they are also semantic variants of any native digits in scripts that also include the common digits. Such variant relations are deemed to exist implicitly by transitivity but are not listed explicitly in each reference LGR. Instead, if needed, they are applied by using the Common LGR in label processing.

In particular, Canadian Aboriginal digit ZERO is a cross-script homoglyph or near homoglyph of digit ZERO in many other scripts; these are already implicit semantic variants by transitivity and therefore not listed here.

To keep digit variant sets manageable in zones where multiple scripts are present, no attempt has been made at identifying cross-script variants among digits of different numeric value or between a digit in one script and a letter in another, such as between digit zero and Latin letter ‘o’. Other mechanisms may be required to prevent homograph labels.

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

Character Classes

The LGR defines the following character classes.

  • final-marks — final marks.
  • Common-digits — the set of ASCII digits.

Whole Label Evaluation (WLE) and Context Rules

The LGR provides script specific restrictions on the allowable placement of initial point code of a label, as well as restrictions on composition. These are implemented with the following rules:

Common Rules

The LGR includes the rules and actions to implement the following restrictions, some of which are mandated by the IDNA protocol. They are marked with ⍟ and included here by default.

  • Hyphen Restrictions — restrictions on the allowable placement of hyphens (no leading/ending hyphen and no hyphen in positions 3 and 4). These restrictions are described in Section 4.2.3.1 of RFC 5891 [150]. They are implemented here as context rule on U+002D (-) HYPHEN-MINUS.
  • Leading Combining Marks — restrictions on the allowable placement of combining marks (no leading combining mark). This rule is described in Section 4.2.3.2 of RFC 5891 [150].
  • Digit-mixing — no mixing between different digit sets (European and Canadian Aboriginal digits) is allowed; implemented here as a WLE rule with associated action.

Language-specific rules in this LGR already prevent combining marks in leading position making the "leading-combining-mark" rule technically redundant. It is retained here for consistency.

Default Actions

This LGR includes the complete set default actions for LGRs as well as the action needed to invalidate labels with misplaced combining marks. They are marked with ⍟. For a description see [RFC 7940] and [150]. An additional action is triggered by mixed digit labels.

Script-specific Rules

The LGR defines the following script-specific rules concerning the placement of final marks and preventing some combinations.

  • leading-final-mark — A context rule on final mark characters that prohibits labels with a leading or repeated final mark, or following a hyphen or digit
  • following-1550 — A context rule that prohibits the character following U+1550
  • following-1595 — A context rule that prohibits the character following U+1595
  • following-1595-or-1596 — A context rule that prohibits the character from following U+1595 or U+1596

Methodology

This Second Level Reference LGR for the Inuktitut Language was developed by the Inuktitut community and edited by Asmus Freytag and Michel Suignard, based on community feedback and public review.

Changes from Version Dated 25 October 2024

Adopted from the Second Level Reference LGR for the Inuktitut Language [Ref-LGR-iu-Cans] without normative changes.

Identity mappings, where a code point is declared a variant of itself, are required by RFC 7940 and are omitted here. 30 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
10 variant sets, containing 20 variants.

Character classes

Named sets of code points that the rules below refer to.

NameDefinition
Common-digits {tag Common-digit} Digits from the ASCII range MSR default
final-marks {tag final-mark} Any final mark

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 any variant is out-of-repertoire-var any variant label with a code point out of repertoire is invalid MSR default
2 blocked any variant is blocked any variant label containing blocked variants is blocked MSR default
3 valid any label default catch all; default action MSR default
