Option 2. CCT as a new vocabulary
Option 1. CCT as a mapping result
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
vocabulary.)
Avoids semantic conflicts in applications
•! Use skos:OrderedCollection to include main classes
•! an integration of the national standards Chinese Library
Disadvantages:
and used skos:memberList to show the member in an
Classification (CLC) and Chinese Thesaurus (CT)
Complicated
order.
•! a manually created mapping product, providing for each of the Time-consuming
2. Alternative classification notations

e.g., [Q89] environmental biology
Preferred class: X17
One presentation for both
Other issues:
•! synthesized numbers

2. CCT Format

•! the add or divide like numbers
3. Top Concept types…for auxiliary tables, etc.

e.g., “hasTopTableConcept” another part of the schedule.
•! parallel schedules

3. Current CCT Online Interface for one class
e.g., the ‘law’ class has two parallel schedules.
4. Notations are constructed in various ways…
