Abstract

Achieving internationalized access to domain names raises many complex issues. These are associated not only with basic protocol design, such as how names are represented on the network, compared, and converted to appropriate forms, but also with issues and options for deployment, transition, registration, and administration.

IESG Note

The IESG congratulates the Joint Engineering Team (JET) on developing

mechanisms to enforce their desired policy. The Language Variant

Table mechanisms described here allow JET to enforce language-based

character variant preferences, and they set an example for those who

might want to use variant tables for their own policy enforcement.

The IESG encourages those following this example to take JET's

diligence as an example, as well as its technical work. To follow

their example, registration authorities may need to articulate

policy, develop appropriate procedures and mechanisms for

enforcement, and document the relationship between the two. JET's

LVT mechanism should be adaptable to different policies, and can be

considered during that development process.

The IETF does not, of course, dictate policy or require the use of

any particular mechanisms for the implementation of these policies,

as these are matters of sovereignty and contract.

RFC 3743 JET Guidelines for IDN April 2004

The IETF Standards for Internationalized Domain Names, known as

"IDNA", focuses on access to domain names in a range of scripts that

is broader in scope than the original ASCII. The development process

made it clear that use of characters with similar appearances and/or

interpretations created potential for confusion, as well as

difficulties in deployment and transition. The conclusion was that,

while those issues were important, they could best be addressed

administratively rather than through restrictions embedded in the

protocols. This document defines a set of guidelines for applying

restrictions of that type for Chinese, Japanese and Korean (CJK)

scripts and the zones that use them and, perhaps, the beginning of a

framework for thinking about other zones, languages, and scripts.
