A pilot study in which a variety of selected CCT classes and mapped thesaurus entries are encoded with SKOS. Two models of encoding an integrated KOS vocabulary are compared. Presented at DC2008, International Conference on Dublin Core and Metadata Applications, Berlin, 2008-Sept. 22-26. Also on: http://dc2008.de/wp-content/uploads/2008/09/zeng-fan-lin-poster-small.pdf

Beyond thesauri, there are issues:
1. CCT Vocabulary Treat newly coordinated terms and notations as labels of
Advantages:
1.! The order of main classes/ schedules concepts. (They did not exist in the original source
•! a collected effort led by the National Library of China Semantic relationships are clear

Avoids semantic conflicts in applications
•! Use skos:OrderedCollection to include main classes
•! an integration of the national standards Chinese Library
Disadvantages:

•! a manually created mapping product, providing for each of the Time-consuming
