  1. Metadata in Satellite Images, or, An Administrator’s View Prepared for the CUL Metadata Working Group August 15 2003 Karen Calhoun The Orion Nebula

  2. The Push Toward Integration • “All together now” • Systems integration: e.g., pulling together pieces that the Internet helped to break apart • Trade integration and currency integration: e.g., the Euro • Living in a BOTH/AND world Calhoun, Metadata WG

  3. Information Silos 7 UNDERGRADUATE COLLEGES AND SCHOOLS, 7 GRADUATE/PROFESSIONAL COLLEGES AND SCHOOLS 19 LIBRARY SYSTEM PUBLIC SERVICES “INFORMATION NETWORK” PROCESSES TECH SERVICES COLLECTION DEVELOPMENT IT Calhoun, Metadata WG

  4. Knowledge Pyramid of the Intelligent Organization (from Chun Wei Choo) DOMAIN EXPERTS Knowledge creation and use Organization effectiveness THE UNIVERSITY COMMUNITY INFORMATION EXPERTS Knowledge organization Enlightenment IT EXPERTS Knowledge infrastructure Process efficiency Calhoun, Metadata WG

  7. B.W. For finding and managing library materials (mostly print) Catalog records (AACR and MARC) Shared cooperative cataloging systems Usually handcrafted, one at a time Highly structured and content-rich Expensive A.W. For finding and managing many types of materials, for many user communities Many types of records Many metadata repositories (most not shared or sharable) Sometimes handcrafted, sometimes machine-made, sometimes both Varied structure and content Can be less or more expensive than library cataloging Evolution: Metadata B.W. and A.W.

  8. Who will be using the digital collection, and how? How large is the digital project? What software and hardware will you use? What is the role of metadata in the project, and at what point will it be created? What is the workflow? What is the desired scope and depth of the metadata records? Who will be creating the metadata, and how? Is there existing metadata? Is staffing adequate? Can you afford the metadata you want? What standards will you use or adapt? Who needs to be involved in decision-making? How will this metadata be integrated into the library’s other collections, databases or catalogs? Metadata projects: a checklist of questions to consider

  9. Metadata and Information Systems • Key problems and issues • Next generation library systems • ENCompass (Endeavor) • MetaLib (Ex Libris) • Others • Metadata’s role Calhoun, Metadata WG

  10. Key Problems and Needs • PROBLEMS • Countless information resources, little time • Searchers on their own to be aware of collections, know how to link, know how to search • WE NEED TO HELP USERS QUICKLY AND CONVENIENTLY… • Learn what collections are available • Learn which collections are relevant to their needs • Find the particular parts of collections that meet their needs

  11. Mapping and Crosswalks • Basis for sharing, reusing, redistributing metadata • Basis for integrating multiple metadata types for federated searching (simultaneous searching of multiple collections) Calhoun, Metadata WG

  12. Interoperability • Defined by CC:DA as: • “The ability of two or more systems or components to exchange information and use the exchanged information without special effort on either system.”

  13. A Next Generation Library System • Manages metadata diversity • Integrates heterogeneous metadata types for searching • Provides federated searching of local and remote collections • Provides seamless linking among related information objects (e.g., a citation and the full text of the article) • Both “pushes” content out and “pulls” it in • Library content more integrated into the Web presence of the university as a whole
