Description

Since 2015, Culture and Art Publishing House (CAAPH, 文化艺术出版社) has gradually established a series of digital projects, including, but not limited to, its official website, an official WeChat account, and Weidian, Weibo, Douyin, Bilibili, and Xiaohongshu accounts. All of the publications will be simultaneously published in digital form, including ePub, Mobi, xml, and other formats. Most of the publications are published as composite works (复合出版物), which means that they print QR codes on the books, and readers could scan the QR codes to use the digital resources in their databases. In 2017, CAAPH established a long-term digital project to digitize some Chinese traditional musical notations. In 2021, they undertook the task to establish and operate the website and database for the Chinese National Center for Contemporary Art of the Chinese Academy of Arts (中国艺术研究院国家当代艺术研究中心), which is also a long-term project. Since 2025, they have been establishing a newer and larger database that provides more information on Chinese culture and Intangible Cultural Heritage (ICH, 非物质文化遗产).

The purpose of the proposed CAAPH IVD collection is to register IVSes for a number of ideograph variants that are very useful for supporting the digitization of Chinese culture and ICH.

The following table provides descriptions of the uppercase Latin characters that serve as first character of the sequence identifiers, the first four of which are based on the Chinese Library Classification (CLC, 中国图书馆分类法/中图法):

Source	Prefix	Description
CLC	B	Philosophy and religions — 哲学、宗教
	G	Culture, science, education and sports — 文化、科学、教育、体育
	J	Art — 艺术
	K	History and geography — 历史、地理
CAAPH	M	Necessary basic glyphs whose style matches Tōngyòng Guīfàn Hànzìbiǎo (通用规范汉字表) and the GB/T 22321.1-2025 standard

NOTE: Four uppercase Latin characters — L, M, W, and Y — are not defined by CLC, which CAAPH uses for other purposes, such as M that is described in the table above.

History

The proposed CAAPH IVD collection and its initial set of sequences were submitted for registration as PRI #521, Combined registration of the CAAPH collection and of sequences in that collection, whose review period closes on 2025-07-11.

That is all.
