Evolution: Metadata B.W. and A.W. 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

Metadata projects: a checklist of questions to consider 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?

8/15/03Calhoun, Metadata WG9 Metadata and Information Systems Key problems and issues Next generation library systems –ENCompass (Endeavor) –MetaLib (Ex Libris) –Others Metadata’s role

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

8/15/03Calhoun, Metadata WG11 Mapping and Crosswalks Basis for sharing, reusing, redistributing metadata Basis for integrating multiple metadata types for federated searching (simultaneous searching of multiple collections)

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.”

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
