Description of Working Group:

The goal of the group is to specify the requirements for
internationalized access to domain names and to specify a standards
track protocol based on the requirements.

Domain names and host names are forms of identifier. Language
information is not encoded in these identifiers; that is, "names" from
different languages are defined in a single namespace.

The scope of the group is to investigate the possible means of doing
this and what methods are feasible given the technical impact they will
have on the use of such names by humans as well as application programs,
as well as the impact on other users and administrators of the domain
name system.

A fundamental requirement in this work is to not disturb the current use
and operation of the domain name system, and for the DNS to continue to
allow any system anywhere to resolve any domain name.

The WG work may modify the DNS protocol and other related work
undertaken by the DNSEXT WG. But such changes must be co-ordinated with
the DNSEXT WG.

The WG will reference work from ISO/IEC, the Unicode Consortium as much
as possible. The consideration are the policy and principle adopted by
the I18N group on the stability of published codepoints and future
addition
of codepoints. The discussion of new codepoints, codepoints properties
and
mappings between codepoints are out-of-scope for the working group and
should be done in other relevant expert group.

The group will not address the question of what, if any, body should
administer or control usage of names that use this functionality.

The group must identify consequences to the current deployed DNS
infrastructure, the protocols and the applications as well as transition
scenarios, where applicable.

The WG will actively ensure good communication with interested groups
who are studying the problem of internationalized access to domain
names.

The Action Item(s) for the Working Group are

1. An Informational RFC specifying the requirements for providing
   Internationalized access to domain names. The document should
   provide guidance for development solutions to this problem,
   taking localized (e.g. writing order) and related operational
   issues into consideration.

2. A standard track specification on access to internationalized
   domain names including specifying any transition issues.

3. A standard track specification on an ASCII Compatible Encoding
   (ACE). This may or may not be used in the standard track
   specification on access to internationalized domain names.

4. A standard track specification on normalization of identifiers
   for the purpuse of comparisons. This document may includes case
   folding, map outs, and prohibited characters.
