PRI 187: Second registration of sequences for the Hanyo-Denshi collection


A submission for the "Second registration of sequences for the Hanyo-Denshi collection" has been received by the IVD registrar. This submission is currently under review according to the procedures of UTS#37, Unicode Ideographic Variation Database, with an expected close date of 2011-10-05.

At the end of the review period, the submission has been incorporated into the 2012-03-02 version of the IVD, with minor adjustments, as 8,850 additional registered IVSes for the Hanyo-Denshi collection.

This page remains available for archival purposes.

Review instructions

Reviewers are encouraged to comment on any aspect of the submissions, but more particularly on:

  • whether the glyphic subset corresponding to a proposed sequence is indeed a glyphic subset of the base character for the sequence
  • whether the proposed sequences are congruent with the scope of their collection, or whether a new collection may be more appropriate

All comments should be sent via the reporting form and will be forwarded to the submitter. The content of the submission may be adjusted during the review period to account for the comments received.

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.
