ITSCJ(Information Technology Standards Commission of Japan) SC2 Committee (JSC2) which is Japan National Body to JTC1/SC2, is going to submit new IVD collection named Moji_Joho Collection to the registrar, Unicode Consortium. JSC2 requests all concerned experts to kindly review and send any comment for the draft of the collection.
[Back ground of Moji_Joho Collection]
These several years, there preceded a governmental project to gather and consolidate all ideographic characters used for governmental residents administrative use from glyphic point of view, called Moji Joho Kiban project (文字情報基盤整備事業), conducted by Moji Joho Kiban committee under IT Strategic Headquarters (an organization within Japanese Cabinet).
Some glyphs, which have no corresponding code position in UCS, are already proposed to ISO/IEC JTC1/SC2/WG2/IRG as candidate characters to be standardized in CJK Unified Ideographs extension F.
Some glyphs, which share UCS code position under Unification Rule, should be treated with IVS mechanism. So, the committee decided to register such glyphs as a new collection in IVD, and asked JSC2 to be registrant on behalf of the committee.
Recently Japanese cabinet decided that the fruit of the project should be used for development of new governmental IT systems in principal. Accordingly, this registration process is very urgent and important to advance Japanese IT policy.
[Note about shared IVSes among collections]
Moji_Joho collection is the very first collection, which shares IVSes with a proceeding collection, Hanyo-Denshi Collection.
Hanyo-Denshi project is the predecessor of Moji Joho Kiban project, and Moji Joho Kiban project inherited a lot of the fruit of Hanyo-Denshi project. Accordingly, Moji_Joho collection shares almost all IVSes with already registered Hanyo-Denshi collection, with a few exceptions. Also, Moji_Joho collection contains newly added glyphs to have new IVSes.
JSC2 proposes to register the first set of ideographic variation sequences in the Moji_Joho collection. The proposed list of ideographic variations as well as their identifiers and representative glyphs are available as http://mojikiban.ipa.go.jp/mjc/1/list_of_glyphs_MJ20131122.pdf (37MByte).
A tentative version of the IVD text file for registration is available as http://mojikiban.ipa.go.jp/mjc/1/IVD_Sequences_MJ20131129.txt. The format of the file is specified in 4.2 of Unicode Technical Standard #37. It is a tentative file to help reviewing.
