  • 16. Dibrary is preparing for a change after 4 years opening
  • 17. The new direction of Dibrary can be summarized as follows 25
  • 18. Semantic Web(Linked Open Data)• What Dibrary (NLK) can do to open its library data?  Converting national bibliographic data, subject and author authority files into linked data and let anyone to use them via the Web.• What will be benefits of NLK LD?  Merging NLK Linked Data with other LLD so new associations of knowledge can be made. 26
  • 19. "The Semantic Web is an extension of the current web in which information is given well-defined meaning, betterenabling computers and people to work in cooperation." Tim Berners-Lee, James Hendler, Ora Lassila, The Semantic Web, Scientific American, May 2001

  • 21. Linked Data Principles1. Use URIs as names for things.2. Use HTTP URIs so that people can look up those names.3. When someone looks up a URI, provide useful RDF information.4. Include RDF statements that link to other URIs so that they can discover related things. Tim Berners-Lee 2007 http://www.w3.org/DesignIssues/LinkedData.html

  • 35. The Principles of Linked Data (Revisited)• What kind of library data are suitable for these principles? – Those that are frequently referenced and updated by librarians, in relation to their works or within the information process system – Those that provide users with links as other references (links) in relation to more accurate search results – Those that are meaningful in themselves and are independently capable of being referenced by other organizations/systems – Those that have values capable of being recognized as unique information via URI 44
  • 36. The Principles of Linked Data (Revisited)• Data owned by libraries: – Bibliographic data – Holdings records – Authority records • Authors, Titles, Subject Headings • Those being endlessly referenced and updated by librarians, in relations to their works, or within the information process system • Those providing links as other references (links) in relations to the more accurate search results to users • Those that are meaningful themselves and independent ones capable of being referenced by other organizations/systems • Those capable of being recognized with their values as unique information through URI 45

  • 50. Smart Data and its Potentials• Implications of Linked Data and Users – Importance of making data smarter • Libraries provide countless amounts of information and media • Libraries need to be a trustworthy entity • Libraries must be placed where permanent access to and preservation of data are guaranteed • Libraries should remain faithful to their most basic and natural role – Providing users with diverse solutions to problems • How do users think and solve problems? • Is it possible to create a system configuration (interface configuration) to assist users’ problem-solving process? 59
  • 51. NLK LLD Strategy• The first priority is opening NLK data – Basically NLK data is a public data that should be open to anyone. – The NLK must be open and easily accessible to others• Try hard to use global standard formats when opening NLK data – Recommend to respect linked data principles when opening• Contribute to information ecosystem. – The Web is most general and accessible platform and ecosystem. Contribute to the Web.• Think more about contributing to the global database (Web) rather than what NLK will gain from this endeavor. – The NLK focus should be on providing the world with new opportunities derived from the live NLK linked data, instead of thinking about what NLK will gain by opening its data 60
