Thema Implementation: Practical Considerations
...
Thema is a subject classification system designed to support trade book publishing. Like the familiar BISAC or BIC systems, the idea is not to create an exhaustive subject system to describe all possible subjects (formal library subject systems do that better) but a. A book trade subject system is more contained, easier to learn and apply. They It only support supports classifications where a reasonable number of published books exist.
What differentiates Thema from BISAC or BIC is Thema supports both international and national marketing of books while BISAC and BIC represent the subject needs of a single market. Thema does this by combining a single international Subject Category list with six Qualifier Code lists. Each Qualifier Code lists provide generic values common to all markets, but when appropriate Qualifier lists can include country specific codes – National Extensions -- that allow each list to be subdivided as granularity as the individual country needs. (See Thema Basics for details) Other countries (or markets) can use or ignore that detail because the code system is hierarchical and the source "international codes" are always available. Thema works for international markets and each country can personalize the lists for use within their own supply chain.
