Description

From 2002 through 2009, three organizations—National Institute for Japanese Language and Linguistics (NINJAL; 国立国語研究所; kokuritsu kokugo kenkyūjo), Information Processing Society of Japan (IPSJ; 情報処理学会; jōhō shori gakkai), and Japanese Standards Association (JSA; 日本規格協会; nihon kikaku kyōkai)—collaborated on a project named 汎用電子情報交換環境整備プログラム (han’yō denshi jōhō kōkan kankyō seibi puroguramu; General Purpose Electronic Information Interchange Environment Preparatory Program), which was funded by Japan’s Ministry of Economy, Trade and Industry (METI; 経済産業省). The project, which was based on three major administrative systems—住民基本台帳ネットワーク (jūmin kihon daichō nettowāku; Residential Basic Ledger Network), 新戸籍システム (shin koseki shisutemu; New Family Registry System), and 新登記システム (shin tōki shisutemu; New Commercial Registry System)—first examined their proprietary Japanese coded character sets, then identified kanji in those coded character sets, and finally arranged them into a list. The list, known as 文字一覧表 (moji ichiran hyō), was published in early 2009 as a series of twelve volumes, and became a part of the project’s final report.

The twelve volumes of 文字一覧表 contain tens of thousands of kanji collected from the three administrative systems. The Japanese National Body proposed to the IRG kanji that were not included in UCS (Universal Character Set; aka the Unicode Standard) as candidates for CJK Unified Ideographs extensions. However, the identification and arrangement of the list was based on administrative requirements and on the program’s own guidelines, and contained many instances whereby a group of kanji that would normally be unified under the Han Unification rules were distinguished in the list. The Japanese National Body proposed to register an IVD collection so that, in the future, Japanese administrative systems can use UCS and continue to distinguish all kanji in the list.

In summary, the Hanyo-Denshi IVD collection ultimately consists of the glyphs that were characterized in 文字一覧表 of 汎用電子情報交換環境整備プログラム.

Although the contents are unofficial, more details about 汎用電子情報交換環境整備プログラム and the Hanyo-Denshi IVD collection, to include the meaning of the sequence identifiers, can be found here.

History

The first set of registered IVSes resulted from PRI #167, Combined registration of the Hanyo-Denshi collection and of sequences in that collection, whose review period closed on 2010-06-25. The Hanyo-Denshi IVD collection, along with its initial set of 4,195 IVSes, were registered in the 2010-11-14 version of the IVD.

The second and final set of registered IVSes resulted from PRI #187, Second registration of sequences for the Hanyo-Denshi collection, whose review period closed on 2011-10-05. 8,850 additional IVSes were registered in the 2012-03-02 version of the IVD.

The total number of registered IVSes in the Hanyo-Denshi IVD collection is therefore 13,045. No further registration of IVSes is expected for the Hanyo-Denshi IVD collection.
