Classification - is categorization and organization based on shared qualities or characteristics. In book metadata, this involves categorizing books using defined codes or subject lists (controlled vocabularies) to describe a book's content.
Controlled Vocabulary - a selected list of words and phrases used to reduce ambiguity and ensure consistency in description. BISAC Subject Headings, ONIX Code Lists, and Thema are examples of controlled vocabularies. Thema provides global standards for subject heading codes and was released in April 2013. Controlled vocabularies also provide consistency in interpretation of metadata transmitted and processed electronically. Words and phrases may also be represented by codes that further reduce error in machine interpretation. For example, the BISAC Subject Headings are also represented by codes, such as BUS090010, which has a literal translation of BUSINESS and ECONOMICS/E-Commerce/Internet Marketing. The ONIX Contributor Code A01 indicates that the contributor name provided is the author of the book. Other codes indicate, editor, illustrator, and other contributor roles. Controlled vocabularies make it more likely that someone seeking information would retrieve a relevant set of items in a search.
