Since the beginning of January, I have started a new, exciting project — cataloguing my books using the analytic and logical Universal Decimal Classification (UDC) system.
My books are currently arranged according to the Chinese Library Classification (CLC, 中国图书馆分类法). Despite its simplicity, especially given the many Mandarin Chinese books my family owns, this system is traditionally limited to a hierarchical breakdown of subject areas. Synthetic categorization, such as the relation between subject areas, the language the work is in, the era the work covers, etc., are not possible.
With UDC, however, the ontology contains auxiliary data structures that enrich the categorization of all kinds of works, from books to electronic files.
The rollover from CLC to UDC is relatively straightforward, but very time-consuming, given UDC’s structural conventions and availability limitations. You can find a free, limited version of the UDC structure here.
