Abstract
Many Chinese characters in common use have variants, which makes most
of the Chinese Domain Names (CDNs) have at least two different forms.
The equivalence between Simplified Chinese (SC) and Traditional
Chinese (TC) characters is very important for CDN registration. This
memo builds on the basic concepts, general guidelines, and framework
of RFC 3743 to specify proposed registration and administration
procedures for Chinese domain names. The document provides the
information needed for understanding and using the tables defined in
the IANA table registrations for Simplified and Traditional Chinese.

1. Introduction
With the standardization of Internationalized Domain Names for
Application (IDNA, described in [RFC3490], [RFC3491], and [RFC3492]),
internationalized domain names (IDNs), i.e., those that contain non-
ASCII characters, are included in the DNS, and users can access the
Internet with their native languages, most of which are not English.
However, many languages have special requirements, which are not
addressed in the IDNA RFCs. One way to deal with some of the
remaining issues involves grouping characters that could be confused
together as "variants". The variant approach is discussed in RFC
4290 [RFC4290] and specifically for documents written in Chinese,
Japanese, or Korean (CJK documents), in the so-called "JET
Guidelines" RFC 3743 [RFC3743]. Readers of this document are assumed
to be familiar with the concepts and terminology of the latter. The
guidelines specified in this document provide a set of specific
tables and methods required to apply the JET Guidelines to Chinese
characters. For example, changes were made in the forms of a large
number of Chinese characters during the last century to simplify
writing and reading. These "Simplified" characters have been adopted
in some Chinese-speaking communities, while others continue to use
