    19. 20. Fiction
    20. 21. Fiction ISBN search
    21. 22. Fiction With fiction, customer mostly not interested in specific edition Just a copy in their language Movie? Da Vinci’s painting? FRBR? Samarcande – French/Belgian Union Catalogue project
    22. 23. Fiction Editions…. Movie? Only 1 dvd!
    23. 24. FRBR – Movie Work Expression An Expression of the Work A new Work
    24. 26. RDA – Movie (as Work) <ul><li>… </li></ul><ul><li>Form of work : motion picture </li></ul><ul><li>… </li></ul><ul><li>Content type : two-dimensional moving image </li></ul><ul><li>… </li></ul><ul><li>Type of recording : digital </li></ul><ul><li>Media type : video </li></ul><ul><li>Carrier type : videodisc </li></ul><ul><li>Encoding format : DVD video </li></ul><ul><li>… </li></ul>Work Expression Manifestation Physical copy

    26. 28. And then there’s the painting
    27. 29. Fiction
    28. 30. Fiction ? No FRBR here ?
    29. 31. Literature Short descriptions of other Works Many authors Koninklijke Bibliotheek – National Library
    30. 32. Literature Content?
    31. 33. Literature Online exhibition Not linked from Catalogue
    32. 34. Literature Link back to catalogue record for compilation Link to original Work in catalogue
    33. 35. Philoso phy Reprints of original texts by Spinoza Biographic notes (original work by editor) Edition information
    34. 36. Philosophy Content? No information about Spinoza, historical, cultural background, influences
    35. 37. Painting Music Archives History Images People are interested in information, subject areas Not necessarily in traditional library items (publications, documents)
    36. 38. FRBR – so far so good? <ul><li>Improvement: relations between editions, authors, subjects. </li></ul><ul><li>But: still focused on traditional library material </li></ul><ul><li>Publications (physical and digital) </li></ul><ul><li>Only library’s own holdings </li></ul><ul><li>Journals/articles? </li></ul><ul><li>Hierarchical, no horizontal relations </li></ul><ul><li>Document centric, not information centric </li></ul>
    37. 39. Linked (Open) Data – Why? <ul><li>Make introverted systems extroverted </li></ul><ul><li>Combine information from different sources </li></ul><ul><li>Add value for users </li></ul>
    38. 40. Linked (Open) Data – How? <ul><li>Make implicit links explicit </li></ul><ul><li>Add links to/from other sources </li></ul><ul><li>Use URIs </li></ul><ul><li>Use RDF/Triples </li></ul><ul><li>Use Open License </li></ul>
    39. 41. URIs <ul><li>Unique identifiers on the web </li></ul><ul><li>Instead of internal database primary key </li></ul><ul><li> (Dan Brown) </li></ul><ul><li> (The Da Vinci Code) </li></ul>
