  • 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 visibleon engaging external partners in useful collaboration.

  • Overview

  • Collection and user analysisChange creates demand for better data.Growing interest in knowing more about:CharacteristicsGaps and overlapsUseTuning collections based on data.Focus collection spending where creates most value.

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

  • OR objectivesSupport better management decisions byMaking data work Exploring user behaviors.

  • Unplug and playIn 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.

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

  • 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

  • Mmmm.

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

  • Terminology services:Webulating knowledge organizationThe goal of this project is to offer accessible, modular, web-based terminology services. Make vocabularies more available for Metadata creationSearching

    Refine and extend mappingsRepresent vocabularies in major encoding standards, e.g., MARC, Zthes, TIFPrototype custom web services as appropriate

  • 2.6+ million fiction records from Worldcat, clustered by OCLCs FRBR algorithmMake greater use of data (genres, settings, imaginary characters, etc)

  • Work display

  • Work/expression display

  • Work/expression/manifestation

  • InteroperabilityExtract maximum value from investment in MetadataContentServicesBy ensuring that they are SharableReusableRecombinable

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

    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.

  • To take the functionality associated with tools for accessing or assigning names, subjects, and classification numbers and make it usable by a wider range of usersto promote the ability to exchange and use information more effectively across language and community boundaries.

    in the international information community and help to guide the activities of librarians so as to enhance these values
