Internationalized Domain Names (IDN) in .museum - Supported scripts and languages

1. Introduction

This document is an adjunct to the policies and terms for the inclusion of IDN in .museum stated at http://about.museum/idn/idnpolicy.html. The material contained in the parent document applies to the implementation of all detail provided below, and describes procedures for the addition of scripts and languages to those listed here. Definitions of terms and abbreviations are given in the parent document.

2. Scripts and languages for which IDN support is currently available

No code points other than those explicitly listed below, or those in documents cited below as containing lists of permissible code points, may be registered in a .museum name. The tables referenced in Section 2 are fully supported. Tables appearing in Section 3 list code points that may provisionally appear in nondelegated names that are used for test or demonstration purposes. They may also be used under similarly restricted terms in names delegated on a case-by-case basis for limited-time use.

2.1. Latin script

A script-based repertoire has been assembled from the Unicode Basic Latin Code Chart, the Unicode Latin-1 Supplement Code Chart, the Unicode Latin Extended-A Code Chart, the Unicode Latin Extended-B Code Chart, and the Unicode IPA Extensions Code Chart. Additional code points may be taken from the Latin Extended Additional Code Chart in the future.

This repertoire is listed in a separate Latin Script Table, together with a discussion of its derivation and the policies attaching to its use.

2.2. Hebrew script

A detailed discussion of support for languages written with characters taken from the Unicode Hebrew Code Chart is provided in a separate document about the specific preparation of a Yiddish character repertoire. In addition to listing permissible code points with the immediate intention of supporting labels derived from the Yiddish language, the table provided there is intended to seed the development of a script-based table that will similarly support the Hebrew and Judeo-Spanish languages, and be further adaptable for other languages subsequently taken into consideration.

3. Other scripts for which IDN support is being developed

Need is anticipated for the scripts listed below, with the further addition of other scripts also expected. A broad character repertoire is described for informational purposes but specific characters may only be used subject to conditions that may be attached to each registered name including them, as determined during the Eligibility and Name Selection ('ENS') phase of the registration process. The appearance of a character in a registered name does not guarantee the availability of that character for inclusion in any other name.

3.1. Arabic script

Support for languages represented with basic and adapted Arabic script is planned for introduction in .museum but policy details are still under development. Individual names may be provisionally activated for purposes of testing prior to their formal delegation. The following documents are currently taken as normative following the most restrictive of any alternative recommendations that may be stated in each, and with the code points and characters permitted for provisional use restricted to those listed in the tables they include:

Arabic http://www.iana.org/domains/idn-tables/tables/sa_ar_1.0.html
Persian http://www.iana.org/domains/idn-tables/tables/ir_fa_1.0.html

3.2. CJK scripts

Support for the scripts used for Chinese, Japanese, and Korean will be introduced in .museum but policy details are still under development. The following documents are currently taken as normative following the most restrictive of any alternative recommendations that may be stated in each, and with the code points and characters permitted for provisional use restricted to those listed in the tables they include:

Chinese http://www.ietf.org/rfc/rfc4713.txt
http://www.iana.org/assignments/idn/cn-chinese.html
http://www.iana.org/assignments/idn/tw-traditional-chinese.html
Japanese http://www.iana.org/assignments/idn/jp-japanese.html
Korean http://www.iana.org/assignments/idn/kr-korean.html

3.3. Cyrillic script

This is intended to support Bulgarian, Kildin Sami, Russian, Serbian, Ukrainian, and other languages that are normally represented with characters taken from the Unicode Cyrillic Code Chart. The following document is currently taken as normative with the code points and characters permitted for provisional use restricted to those listed in the table it includes:

http://www.iana.org/domains/idn-tables/tables/ru_ru-ru_1.0.html

plus the Cyrillic extensions with code points in the range 0450..045F and code points for the small letters in the extended Cyrillic range 048B..04F9.

3.4. Greek script

This will include Greek characters taken from the Unicode Greek Code Chart and the Unicode Greek Extended Code Chart. The following document is currently taken as normative with the code points and characters permitted for provisional use restricted to the SMALL LETTERs listed in the table it includes:

https://grweb.ics.forth.gr/CharacterTable1_en.jsp

but excluding the code point U+03C2.

4. Comments

The links to the Unicode Code Chart provided in this document go to its latest version. The formal IDN protocol specifications are, however, based exclusively on Unicode version 3.2. Characters introduced subsequently to it are not available for use in IDN. Differences between Unicode versions are listed at http://www.unicode.org/standard/versions/. Any sources of actual concern to the holders of names in .museum will be described in future versions of the present document.
