ABSTRACT
Structured metadata-metadata based on organizing principles-can facilitate the task of information retrieval by providing context and meaningful differentiation in search results as well as collocating items with similar characteristics and highlighting semantic relationships among index terms. Types of metadata structure include rule basis, authority control, categorization, and relationship control. Most information found in library catalog records is structured metadata, but online catalog systems often suppress structural features (especially those providing relationship control) through simplified machine sorting of search results. Catalog displays that respect and highlight metadata structures are needed to improve collocation and browsing capability.
