  1. OCLC Research:an update Lorcan Dempseydempseyl@oclc.org

  2. OCLC Research • Mission • Emphasis • Perceptions

  3. Metadatamanagement Interoperability Managementintelligence Knowledgeorganization Systems and interaction design Contentmanagement

  4. Dublin Core ZING … SRU/SRW IMS OAI - PMH Support Visualization Interoperability Systems and interaction design

  5. Management intelligence Under construction Explore how to support management decisions by making better use of available data.

  6. Interlibrary Loan Study • Compare interlibrary loan borrowing patterns within a consortium • Begin with OhioLink • Compare netLibrary holdings to titles borrowed through interlibrary loan

  7. Collection Assessment • Analyze and compare aggregate WorldCat holdings for libraries • ARL • Academic, non-ARL • Public • Identify titles and their intellectual levels, subjects (using conspectus), and publishers

  8. User Behavior Study • Identify how print book and eBooks are used • Focus group interviews • Individual interviews • Transaction log analysis

  9. Metadata switch Under construction • Explore a set of services which add value to metadata by leveraging OCLC expertise and cooperative processing model.

  10. Subject classification service E-Prints UK Name SOAP authority service SOAP Citation analysis Javascript /HTTP service Z39.50 RDN RDN RDNGateway gateway/portal gateway/portal service service E-prints UK Institutional Non - institutional Personal e - print e - print e - print archives archives archives OAI - PMH

  11. Emerging technologies provide opportunities for new services • Tools and features previously available only in integrated systems can now be provided as 'web services' • “network accessible application components” • “interoperable building blocks for constructing applications” • “self-describing applications that can be discovered and accessed over the web by other applications” • Technical definition • Web Services are a suite of protocols that define how requests and responses between software applications should be encoded & transferred over the web

  12. Aggregationand fusion Schematransformation Names Terminologyservices

  13. Aggregation and fusion • OAI • Theses • ?? • Fusion

  14. Record enhancement

  15. Terminology services • Methods effective for print, unlikely to be the same techniques used for digital documents • Need to determine role of knowledge organization (KO) resources in relation to new approaches • Authority files • Subject heading systems and thesauri • Classification schemes

  16. Terminology resources are currently embedded in systems & services • OCLC Connexion • Provides access to several KO schemes & links among schemes • Dewey, LCSH, Name authorities • Automated application tools • Harvest & record creation • Classification • Control of names, subjects, class numbers

  17. Need more flexible, modular knowledge organization services • For example, one set of requirements: • Automatically check name and subject authorities • Automatically supply Dewey Decimal Classification numbers based on subject entries • On-demand check of subject and name authorities in non-OCLC record sources • Authorities notification service • Improve record quality/completeness

  18. Knowledge Organization Services • Record Enrichment • Classes • Subjects • Names • Summaries KO Schemes 635.951 • Classification • Auto-class • Number verification • Captions • Associated Terms • Updates • Authority Control • Auto-assign • Name/Subject validation • Associated Classes • Authorities notification Name Authority Files DDC LCSH

  19. OCLC Web Services Demo Rare and endangered animals Rare and endangered species

  20. Prototypes & Demonstration projects • Prototype • LCCN Web Service Demo (previous slide) • OCLC & Northwestern University • DDC number verification for Cataloger's Toolkit for Voyager ILS • eprints-UK • OCLC will supply subject descriptions & name authorities as Web services for harvested resources

  21. Schema transformation services • Accept metadata in one schema and return metadata in another schema

  22. Names • Accept a name and return • Authoritative version of the name • Cluster of related names

  23. Content management Under construction • Make a leading contribution to the economic and engineering issues facing the digital preservation community.

  24. Digital preservation • OCLC/RLG collaboration • Moving from a consensus making phase to an implementation phase • Real economic and engineering issues being addressed

  25. Economics • White paper

  26. Digital preservation .. engineering • Research fellow • Digital coop
