  7. 7. 2. The Principles of Linked Data<br />Tim Berners-Lee (2007)<br />The Principle of Linked Data<br />Use URIs as names for all conceivable objects.<br />Use HTTP URIs so that people can look up the names of those objects. <br />Provide useful information using the RDF, SPARQL standards when someone looks up a URI.<br />Include links to other URIs so that users can discover more objects.<br />Raw Data!!<br />7<br />

  11. 11. Use HTTP URIs so that people can look up those names.

  13. 13. Include links to other URIs. so that they can discover more things.</li></ul>10<br />
  14. 14. 2. The Principles of Linked Data<br />What kind of library data are suitable for these principles?<br />Those that are frequently referenced and updated by librarians, in relation to their works or within the information process system<br />Those that provide users with links as other references (links) in relation to more accurate search results<br />Those that are meaningful in themselves and are independently capable of being referenced by other organizations/systems<br />Those that have values capable of being recognized as unique information via URI<br />11<br />
  15. 15. 2. The Principles of Linked Data<br />Data owned by libraries: <br />Bibliographic data<br />Holdings records<br />Authority records<br />Authors, titles, subject headings<br /><ul><li>Those being endlessly referenced and updated by librarians, in relations to their works, or within the information process system
  16. 16. Those providing links as other references (links) in relations to the more accurate search results to users
  17. 17. Those that are meaningful themselves and independent ones capable of being referenced by other organizations/systems
  18. 18. Those capable of being recognized with their values as unique information through URI</li></ul>12<br />
  19. 19. 2. The Principles of Linked Data<br />Authority records can be used as linked data<br />LIBRIS<br />The Swedish National Union Catalogue<br />Earlier 2009 year, LIBRIS was published as Linked Data on the web, exposing the entire library state with all its records, links and relations.<br />Authority records<br />Authors, titles, subject headings<br />13<br />
  20. 20. 2. The Principles of Linked Data<br />Linked<br />Data<br />Open<br />First step<br />Open “Authority Data”<br />How?<br />Convert Marc to XML(MarcXchange ?)<br />Assign URIs(HTTP URIs)<br />Use RDF(or Microformats..) to establish relationships<br />Is this really our first priority?<br />14<br />
  21. 21. 2. The Principles of Linked Data<br />Considerations for linked data development<br />Libraries may not be ready for linked data yet. <br />A web of document -> A web of applications -> A web of data<br />We need to re-examine what it is thatwe have. <br />We need to re-think about why we are considering ‘A web of data’.<br />We need to examine our surrounding conditions more carefully and make future plans.<br />15<br />
  22. 22. 2. The Principles of Linked Data<br />Are libraries ready for linked data?<br />Are libraries’ metadata (MARC, Dublin Core…) rich enough to link data?<br />Are libraries’ IT infrastructure ready for ‘open’ environment? Are we ready to comply with open standards?<br />Are IT policies suitable for existing linked data? (URI policies and so on)<br />Are we efficiently coping with license and copyright issues? <br />Can we provide long-term identification and access to those data?<br />16<br />
  23. 23. Can we provide long-term accessibility? <br />17<br />17<br />

  27. 27. 3. Ever Changing Users’ Needs<br />21<br />Who are our clients?<br />Resources to meet users’ needs<br />Information (books, journals, CDs, DVDs, the Web, etc.)<br />Users (people seeking information)<br />
  28. 28. 3. Ever Changing Users’ Needs<br />22<br />Why are user needs hard to predict?<br />The extremely rapid advancement of IT<br /><ul><li>Speedy advent of future technologies
  29. 29. Fractional predictions liable to cause failures
  30. 30. Rapid production and utilization of various digital information resources and media increases likelihood of unpredictability</li></li></ul><li>3. Ever Changing Users’ Needs<br />23<br />The Future Model of the Information Age<br /><ul><li> IT(Information Technology) + BT(Biotechnology) + NT(Nano-technology) </li></ul>01<br />Combination of IT + NT: microminiaturization ofall computing materials<br />02<br />Microminiaturized IT+NT products embedded in the body (BT)<br />03<br />Human bodies embrace media: Advent of ergonomics where human’s five senses are integrated into NT and installed in machines<br />
  31. 31. 3. Ever Changing Users’ Needs<br />24<br />Why are user needs impossible to predict?<br />Users are making the Web more and more of a social space.<br /><ul><li>Users are unable to bear boredom
  32. 32. Users are increasingly turning into producers rather than mere information consumers</li></li></ul><li>Communication<br />= The Strategy for Future Library<br />4. Communication in Library<br />The reason why libraries are concerned with linked data and semantic web<br />25<br />
  33. 33. 4. Communication in Library<br />Users’ Perspective<br />Not being able to find certain information on the Web prompts the assumption that said information not available.<br />I exist = I exist on the network = I am in the network<br />Users are making the Web a social sphere.(Users are the core of what makes the Web social)<br />26<br />

  45. 45. 4. Communication in Library<br />Challenges accompanied by changes in communication<br />In order to manage, preserve, and service digital information using various formats, we must develop suitable management system and metadata elements. <br /> At which point in time should certain information be considered the most recent?<br />Traditional distribution channels cannot satisfy renewed user demands. <br />34<br />

Conclusions<br />Implications of Linked Data and Users<br />Importance of making data smarter<br />Libraries provide countless amounts of information and media<br />Libraries need to be a trustworthy entity<br />Libraries must be placed where permanent access to and preservation of data are guaranteed<br />Libraries should remain faithful to their most basic and natural role<br />Providing users with diverse solutions to problems<br />How do users think and solve problems? <br />Is it possible to create a system configuration (interface configuration) to assist users’ problem-solving process?<br />37<br />
