2. Context- wwwwh
3. Structure

Library Metadata- indexes, abstracts, and bibliographic records by cataloging rules

"there is no single metadata standard that is adequate for describing all types of collections and materials; selection of the most appropriate suite of metadata standards and tools, and creation of clean, consistent metadata according to those standards, not only will enable good descriptions of specific collection materials but also will make it possible to map metadata created according to different community-specific standards,"

Structure role is becoming more important in technology age
