In 2002-2009, three organizations, National Institute for Japanese Language and Linguistics, Information Processing Society of Japan, and Japan Standards Association, jointly worked on a project called 汎用電子情報交換環境整備プログラム (han'yô densi zyôhô kôkan kankyô seibi puroguramu; general purpose electronic information interchange environment preparatory program), that was funded by Ministry of Economy, Trade and Industry. The project picked up three major administrative systems, i.e., 住民基本台帳ネットワーク (zyûmin kihon daityô nettowâku; residential basic book network), 新戸籍システム (sin koseki sisutemu; new family registry system), and 新登記システム (sin tôki sisutemu; new commercial registry system), examined their proprietary Japanese coded character sets, identified kanji in those coded character sets, and arranged them into a list. The list, known as 文字一覧表 (mozi itiran hyô; list of letters) is published as a part of the project's final report.
The 文字一覧表 contains tens of thousands of kanji collected from the three administrative systems. Japan National Body has been proposing kanji that were not included in UCS to IRG as candidates to extensions to CJK unified ideographs. However, the identification and arrangement of the list is based on the administrative requirements and on the program's own guidelines, and it contains many instances that a group of kanji that are to be unified under the UCS criteria are distinguished in the list. Japan national body proposes to register appropriate ideographic variation sequences so that, in a future, Japanese administrative systems can use UCS and still distinguish all kanji in the list.
Hanyo-Denshi collection ultimately consists of the characterized glyphs in 文字一覧表 of 汎用電子情報交換環境整備プログラム.
Japan national body proposes to register the first set of ideographic variation sequences in the Hanyo-Denshi collection. The proposed list of ideographic variations as well as their identifiers and representative glyphs are available as http://www.itscj.ipsj.or.jp/domestic/sc02/hanyo-denshi/20100331/IVS-0322.pdf
A tentative version of the IVD text file for registration is available as http://www.itscj.ipsj.or.jp/domestic/sc02/hanyo-denshi/20100331/IVS_Hanyo-Denshi_0409.txt. The format of the file is specified in 4.2 of Unicode Technical Standard #37. It is a tentative file to help reviewing.
Please note that the order of appearance of the sequences associated with a same base character in this text file or in the PDF chart has no significance except that the glyph most similar to the one shown in J-column of the CJK unified ideographs code charts in ISO/IEC 10646 comes first.
After the closure of review, Japan National Body considered all received comments and decided to update the list of proposed sequences to address the comments. A document containing responses to the comments is produced as well as the updated list of proposed sequences.
A mistake was found in the updated list published on 2010-9-10. An extra glyph that should have been removed during the comment disposition was remained. A set of updated lists follows. They have already been submitted to the Unicode Consortium.
