Metadata switch
Lorcan DempseyMembers’ Council, May 2002
Metadata switch
• Explore a set of services which add value to metadata by leveraging OCLC expertise and position.
• Under discussion with Metadata and Cooperative Discovery Services
• High acronymic density … please shout out!
Proposition
• Add value to metadata created elsewhere– Aggregate metadata for reuse– Leverage knowledge structures – Investigate schema interoperability services
• An initiative which builds on OCLC’s ‘cooperative processing’ strengths
• ‘Open metadata services’
Environment
• Major digital initiatives as part of learning, research and cultural engagement
• Libraries looking at management and disclosure of institutional assets
• Growing importance of unique, non-published materials– Learning materials, research data, technical
reports, e-prints

Don’t do it?
• Share of metadata creation declines• Become peripheral to major activities in
information management for research and learning
• Increasingly marginal to many ‘digital library’ initiatives on campus
• Lose potentially valuable ‘reference’ resources
Next steps
• Aggregator– NDLTD– Learning objects– Contentdm
• KONA– Under development
• Schema trans– Investigation
• Will work with CMS• Exploratory
• Diane VG’s group
