3. 1. Introduction 3 Linked Data and Users in the LibraryDoes the library communicate efficiently?

4. 1. Introduction 4 The Semantic Interoperability of Linked Data

5. 1. Introduction [The Linking Open Data dataset cloud] Bibliographic 5

6. [The Semantic Web Layer Cake] User Interface & Applications Trust Crypto Proof Unifying Logic Rules: RIF Ontology: OWL Vocabulary: SKOS Query: SPARQL RDF-S Data Interchange: RDF XML URI Unicode [W3C, 2007] 1. Introduction 6

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

8. 2. The Principles of Linked Data The Web of Documents 8

9. 2. The Principles of Linked Data The Web of Data 9

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

12. When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)

13. Include links to other URIs. so that they can discover more things.10

14. 2. The Principles of Linked Data 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 11

16. Those providing links as other references (links) in relations to the more accurate search results to users

17. Those that are meaningful themselves and independent ones capable of being referenced by other organizations/systems

18. Those capable of being recognized with their values as unique information through URI12

19. 2. The Principles of Linked Data Authority records can be used as linked data LIBRIS The Swedish National Union Catalogue Earlier 2009 year, LIBRIS was published as Linked Data on the web, exposing the entire library state with all its records, links and relations. Authority records Authors, titles, subject headings 13

20. 2. The Principles of Linked Data Linked Data Open First step Open “Authority Data” How? Convert Marc to XML(MarcXchange ?) Assign URIs(HTTP URIs) Use RDF(or Microformats..) to establish relationships Is this really our first priority? 14

21. 2. The Principles of Linked Data Considerations for linked data development Libraries may not be ready for linked data yet. A web of document -> A web of applications -> A web of data We need to re-examine what it is thatwe have. We need to re-think about why we are considering ‘A web of data’. We need to examine our surrounding conditions more carefully and make future plans. 15

22. 2. The Principles of Linked Data Are libraries ready for linked data? Are libraries’ metadata (MARC, Dublin Core…) rich enough to link data? Are libraries’ IT infrastructure ready for ‘open’ environment? Are we ready to comply with open standards? Are IT policies suitable for existing linked data? (URI policies and so on) Are we efficiently coping with license and copyright issues? Can we provide long-term identification and access to those data? 16

23. Can we provide long-term accessibility? 17 17

24. 2. The Principles of Linked Data ISSUE Semantic(Linked data) Search engine. RDF Browser Linking algorithms User interaction and interface Publishing legacy data sources as Linked Data on the Web Licensing and other legal issues N-Triple transformation Database (support SPARQL) Identifier management 18

25. Why are libraries considering Linked data and semantic web? 3. Ever Changing Users’ Needs http://www.flickr.com/photos/jakecaptive/3205277810/ 19

26. The needs of our clients are changing. It is also difficult to predict clients’ changing needs. 3. Ever Changing Users’ Needs http://www.flickr.com/photos/chavals/2344906748/ 20

27. 3. Ever Changing Users’ Needs 21 Who are our clients? Resources to meet users’ needs Information (books, journals, CDs, DVDs, the Web, etc.) Users (people seeking information)

29. Fractional predictions liable to cause failures

33. 4. Communication in Library Users’ Perspective Not being able to find certain information on the Web prompts the assumption that said information not available. I exist = I exist on the network = I am in the network Users are making the Web a social sphere.(Users are the core of what makes the Web social) 26

34. 4. Communication in Library Facebook Slideshare Twitter Flickr Blog PC, Mobile, Anytime, Anywhere 27

35. 4. Communication in Library [SEMTECH 2007] [http://www.faviki.com/blog/keyword_search.gif] 28

37. New routes for information searches

38. The fast distribution of the latest information filtered to a user’s interest

39. Easy reference of diverse information and opinions

40. Trustworthiness

42. 4. Communication in Library Various attempts made by libraries Services through libraries’ search systems Exposing library resources via metadata Linking search engines and services Linking blogs and SNS services 31

43. 4. Communication in Library Traditional library Physical Materials Library User 32

44. 4. Communication in Library Digital library [Web] [CD/DVD] [Text, Audio, Video] Physical Digital [Web] Library User [PC] [Mobile] [Creator] [User] Create Information 33

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

77. 5. Conclusions 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? 37
