  • Die schwedische Nationalbibliographie als Linked Data

    LIBRIS, the Swedish union catalog used for cataloging by approximately 170 library institutions and home of the Swedish National Bibliography, has since the beginning of 2008 been available as Linked Open Data. The service is a work in progress, and in this presentation Anders will describe the strategic thinking behind the LIBRIS Linked Data project, as well as the thoughts and ideas that have emerged as a consequense of it. Such ideas will include the implications of viewing bibliographic information as open networks of data, rather than as closed (or semi-closed) repositories of records. The presentation will also include a discussion of how and why libraries should use linked data as a way of connecting to the rest of the world wide web.

LIBRIS - Linked Library Data

  1. 1. LIBRIS - Linked Open Library Data Anders Söderbäck National Library of Sweden
  2. 2. What is LIBRIS? • Swedish union catalog • Library directory • Library infrastructure • Search interface / OPAC
  3. 3. What is LIBRIS? • Existance since 1970 • Online public access (for humans) since 1997 • Open (or semi-open...) bibliographic records since 1997 • Marc21 since 2001 • Linked Open Data since 2008
  4. 4. LIBRIS Union Catalogue • 175 libraries • 6 million bib records • 20 million holdings • 250k authority records • National bibliography
  5. 5. LIBRIS Library Directory • Roughly 2000 libraries • ILL information • Administrative information • Technical information • Geographic locations
  6. 6. LIBRIS as Infrastructure
  7. 7. LIBRIS as Infrastructure • Human Cataloging • Automated imports of data • Automated exports of data • Open APIs • LIBRIS-ID master identifier for bibliographic data in Sweden
  8. 8. Why Linked Data?
  9. 9. New LIBRIS web interface • Project 2006-2007 • Launch dec 2007 • ”Next-Gen OPAC”
  10. 10. New LIBRIS web interface • Lots of effort in design • Lots of user testing, interviews, user centered design... • Lots of input from mixed reference group
  11. 11. What does the world want from us? • Good, usable interface • Data • APIs...
  12. 12. What doesn’t the world want from us? • Library specific protocols • Neither z39.50 nor ISO2709
  13. 13. Design a thing by considering it in its next largest context - a chair in at room, a room in a house, a house in an environment, environment in a city plan. - Eliel Saarinen
  14. 14. A library catalog must be designed by considering its context of the Web.
  15. 15. The trouble with APIs... • We have made quite a few of them... • Bigger demand for APIs than we could meet. • APIs tend to limit use to what was intended by the creator of the API • Context specific • ”What if there was a good way to provide all the data..? And all the relations..?”
  16. 16. What is the Web? • An infrastructure • An environment • The Web is social • The Web is made of links • The Web is a network • The Web is an open system
  17. 17. Catalogs in Web context • Need to be open • Need to be linkable • Need to provide links • Need to be part of the network • Can not be an end in itself • Must allow for hackability
  18. 18. Catalog/Web as Network • An infrastructure • Need to be open • An environment • Need to be linkable • The Web is social • Need to provide links • The Web is made of • Need to be part of links the network • The Web is a • Can not be an end in network itself • The Web is an open • Must allow for system hackability

  33. 33. Linked Open Data
  34. 34. Linked Open Data turns the Web into an API. - Corey A. Harper, at code4lib preconf 2009
  35. 35. Linked Data at LIBRIS • Exposes name and subject authorities as foaf:Person, skos:Concept • Bibliographic records as bibo:Book, bibo:Article, etc. • dc:creator, dc:subjects, etc.
  36. 36. So what does it look Linked Data at LIBRIS like? tisdag, 2009 februari 24
  37. 37. Linked Data at LIBRIS HTTP URI for every resource, e.g. http://libris.kb.se/resource/bib/5059476 http://libris.kb.se/resource/auth/220040 http://libris.kb.se/resource/library/S

  39. 39. Linked Data atagain text/rdf+n3 LIBRIS
  40. 40. Linked Data at LIBRIS • Links to dbpedia.org • Links to id.loc.gov • Links to lcsubjects.org
  41. 41. LIBRIS Linked Data Strategies • Data first • Represent ILS state • Use existing vocabularies when possible (DC, SKOS, FOAF, Bibo, Geo, ...) • Make up vocabularies if needed • Learn by doing
  42. 42. So, what about the future?
  43. 43. The future is a work-in-progress...
  44. 44. Links, links, links... • DbPedia • MusicBrainz • id.loc.gov • VIAF • Open Library • ...
  45. 45. Ontologies • Use of existing ontologies will be improved • More information will be added • ...
  46. 46. Problems • Current library systems are not adapted for linked data • Current legal system is not adapted for linked data • Current bibliographic thinking is not adapted for linked data • All this will change...
  47. 47. Library data in the Age of Biology It is likely that biotechnology will dominate our lives and our economic activities during the second half of the twenty-first century, just as computer technology dominated our lives and our economy during the second half of the twentieth. - Freeman Dyson
  48. 48. Principles of Organization From Hugh Dubberly, Design in the Age of Biology http://www.use8.net/magazine.php?ArticleId=101
  49. 49. Viewing the catalog as a So what does it look network... like?
  50. 50. ...raises a lot of questions! • What is a record? • When is a record? • What kind of network is the library catalog?
  51. 51. Network effects arise when the act of participation makes the entire network more useful for everyone. - Ian Davis,Talis
  52. 52. Things to remember • Open networks outpaces walled gardens • Strong networks require more than only one hub • Systems built for delivery of records on magnetic tape (i.e. MARC, LIBRIS in the 70’s) need to change • ‘Good enough’ beats perfection
  53. 53. For what the body catalog can do noone has hitherto determined, that is to say, experience has thought no one hitherto, what the body catalog, without being determined by the mind library, can do... - adapted from Spinoza, Ethics
