Research possibilities

• .. are endless!
• Becoming more complex as more activities enter a
  network space.
• Focus
• on maximizing impact of a limited resource.
• on where can make an internal and external
  impact.
• on making valuable work more visible
• on engaging external partners in useful
  collaboration.

Collection and user analysis
The idea of the balancedbut unreadcollection is
disappearing.
Librarians cannot change user behavior so they
need to meet the user.

• Change creates demand for better data.
• Growing interest in knowing more about
• Characteristics
• Gaps and overlaps
• Use
• Tuning collections based on data.
• Focus collection spending where creates most
  value.

8
OR objectives

• Support better management decisions by
• Making data work
• Exploring user behaviors.

9
Some projects

• Characteristics of collections
• WorldCat
• CIC
• Compare ILL, circulation and holdings data.
• Last copy what is irreplaceable?
• ARL Global Resources.
• Exploring coverage of overseas titles in ARL
  libraries.

• Large scale user behavior study
• IMLS project with OSU and OCLC

System and service architecture

• The library systems environment is getting more
  complex
• ILS
• Digital asset management
• Resolution
• Portal
• Resource sharing
• License management
• Auth

• Build, buy, opensource?
• Integration
• Integrated workflow
• Portal
• Cataloging

16
Unplug and play

• In this model business functionality is unplugged
  from large integrated centralized workflow
  applications so that it can be more readily
  integrated inside local applications and
  workflow. In this way, functionality
  potentially reaches a wider audience, provides
  more value to existing audiences, and extends the
  life of legacy applications.

17
OR objectives

• Investigate new ways of structuring and viewing
  WorldCat and associated knowledge structures
• Exploit emerging technologies, open standards and
  protocols to prototype new services

18
Some projects

• Unplug and play
• Metadata schema transformation
• E-prints UK
• Terminology services
• Name authority services
• XISBN

• Text searching
• Fast searching on Beowulf clusters
• Harvesting
• NDLTD Union Catalog

xISBN

• An experimental web service
• Give it an ISBN, it returns all related ISBNs
• Based on WorldCat
• Designed for machine-to-machine data exchange
• Examples
• Check user ILL requests against all
  editions/versions in OPAC
• Find librarys editions when user finds any
  edition/version of item on Amazon
• Check OPAC for all editions during
  selection/acquisitions/gift book processing

Knowledge organization and semantic web
"The Semantic Web is an extension of the current
web in which information is given well-defined
meaning, better enabling computers and people to
work in cooperation." -- Tim Berners-Lee, James
Hendler, Ora Lassila, The Semantic Web,
Scientific American, May 2001

OR objectives

• To release the value of the historical library
  investment in controlled vocabularies and
  knowledge structures
• Redeploy tools for accessing or assigning names,
  subjects, and classification numbers
• Make knowledge organization services more
  accessible.

30
Projects

• FAST
• Terminology services
• FRBR
• Automatic classification
• VIAF Virtual International Authority File
• Library of Congress, Die Deutsche Bibliothek

Knowledge org systems

• Plethora of vocabularies
• Incompatible approaches to encoding
• Few connections
• Education
• GEM Subjects, ERIC Thesaurus, LCSH, CIP
  (Classification of instructional programs)
• Cultural Heritage
• AAT, Thesaurus for Graphic Materials (TGM)
  Subjects Genre Terms
• Not built for the web
• Link to concepts

33
Terminology servicesWebulating knowledge
organization

• The goal of this project is to offer accessible,
  modular, web-based terminology services.
• Make vocabularies more available for
• Metadata creation
• Searching

• Refine and extend mappings
• Represent vocabularies in major encoding
  standards, e.g., MARC, Zthes, TIF
• Prototype custom web services as appropriate

34

Interoperability

• Extract maximum value from investment in
• Metadata
• Content
• Services
• By ensuring that they are
• Sharable
• Reusable
• Recombinable

40
OR objectives

• Provide leadership in Internet and information
  standardization
• Help to raise the visibility of the values and
  value of librarianship

41
Some examples

• Dublin Core
• Central to library, cultural heritage and related
  communities.
• Harvested data OAI
• 8 Governments
• Corporations and NGOs

• Protocols
• Z39.50, SRW/U, OAI, Zthes
• Identifiers
• INFO URI, PURL
• Registries
• DCMI, OpenURL, Info URI
• Everywhere !

Cliff Lynch on Info URI it represents an
important new step in collaboration ACROSS
standards organizations, and I think the work
is of real importance to the CNI community.
