Representing phonetics for Japanese names in Atom feeds
draft-murata-atom-phonetics-01
Abstract
This specification introduces an attribute for representing phonetics
for Japanese names such as author names and article titles. It is
intended to be used together with the Atom Syndication Format
[RFC4287] and OPDS(Open Publication Distribution System)[OPDS], which
is based on Atom.

1. Introduction
The Japanese language uses kanji (CJK ideographic characters) and
kana(Japanese phonetic characters). A human name or article title is
often represented by two strings: one with kanji and another without
kanji. The latter is used to uniquely identify the phonetics of the
human name or article title. More about this issue, see [Miyazawa].
The Atom Syndication Format [RFC4287] does not provide mechanisms for
representing a name in more than one language or script. This
specification introduces an attribute for representing the phonetics
for a Japanese author name or article title. This attribute is
intended to be used together with the Atom Syndication Format and
OPDS(Open Publication Distribution System)[OPDS], which is based on
Atom.

2. The phonetics attribute
_Namespace:_ http://www.jepa.or.jp/xmlns/atomPhonetics
_Local name:_ phonetics
_Parent element:_ atom:name, atom:title, and atom:subTitle
_Cardinality:_ 0 or 1
_Permissible values:_ Strings in the Japanese language without CJK
ideographic characters. Such strings typically consists of
Katakana or Hiragana characters but may include digits, symbols
and Latin alphabets. [NDL] gives one way to create the phonetics
of a given name and shows commonly used characters for phonetics.
2.1. Example
XML入門
村田
...
"ニュウモン" and "ムラ
x30bf;" are Katakana strings, while "入門" and
"村田" are CJK ideographic character strings.

3. RELAX NG schema
Although the original schema (atom.rnc) allows any foreign attribute,
the following schema is provided as an extension of the original
schema for explicitly allowing and further mandating the phonetics
attribute. Instead of the original schema, this schema MAY be used
for validating atom feeds having phonetics.
namespace atom = "http://www.w3.org/2005/Atom"
namespace jepa = "http://www.jepa.or.jp/xmlns/atomPhonetics/1.0"
namespace local = ""
include "atom.rnc" {
undefinedAttribute =
attribute * - (xml:base | xml:lang | local:* | jepa:*) { text }
atomPersonConstruct =
atomCommonAttributes,
(element atom:name {attribute jepa:phonetics {text }?, text }
& element atom:uri { atomUri }?
& element atom:email { atomEmailAddress }?
& extensionElement*)
atomTitle =
element atom:title
{attribute jepa:phonetics { text }?, atomTextConstruct }
atomSubtitle =
element atom:subtitle
{attribute jepa:phonetics {text }?, atomTextConstruct }
}

4. Schematron schema
This schematron also mandates the phonetics attribute. This schema
MAY be used for validating atom feeds having phonetics. It MAY be
used together with the original schema (atom.rnc) or schemas for
OPDS.
The jepa:phonetics attribute is allowed only
for atom:name, atom:title, and atom:subTitle
elements.
