Metadata Support and Management Help define future research services v System-wide efficiencies in library management v Services where library users are Three broad groups of activities: • Classification & Controlled Vocabularies • Tools and Processes • Works-based and Other Special Views Metadata Support & Management 2011 -06 6

Classification & Controlled Vocabularies • Classify [leveraging WC to support classification assignment] • FAST [LCSH into machinefriendly facets] • Terminology Services [BISAC, Me. SH, more vocabs rendered for machines] • VIAF [one file from many national authority files] Metadata Support & Management 2011 -06 7

Tools and Processes • FAST Converter [demo tool for LCSH-to-FAST conversion] • Metadata Schema Transformation Services [metadata crosswalking] • Name Extraction [pulling names from text] • Sharing and Aggregating Social Metadata [exploring crowdsourcing] Metadata Support & Management 2011 -06 8

Works-based and Other Special Views • Map. FAST [About-place titles shown on a map] • Work Records in World. Cat [1 rich page per work] • World. Cat Genres [1 rich page per genre] • World. Cat Identities [1 rich page person/corporate body/fictional character] • World. Cat Publisher Pages [1 rich page per publisher] Metadata Support & Management 2011 -06 9
