Linked data as a library data platform

  1. 1. Linked Data as a Library Data Platform A Proof of Concept from National Technical Library of Czech Republic Jindřich Mynarz National Technical Library ELAG 2010 Helsinki June 10th 2010
  2. 2. Overview  Library data  Linked data  Converting library data to linked data  Distribution  Benefits of linked library data
  3. 3. Library data are not very readable
  4. 4. Source: National Library of the Czech Republic card catalogue Catalog card - record
  5. 5. MARC Record CAPTCHA - Completely Automated Public Turing test to tell Cataloguers and Humans Apart
  6. 6. Library data in XML are still not very readable
  7. 7. Library-specific access protocols (Z39.50, OAI-PMH)

  10. 10. Linked data principles Thou shalt:  Use URIs as names for things.  Use HTTP URIs so that people can look up those names.  When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL).  Include links to other URIs. so that they can discover more things.

  12. 12. Data conversion  Choosing datasets  Choosing description  Extraction  Linking  Distribution
  13. 13. Choosing description  Domain ontologies  Established, popular (Dublin Core, SKOS) Falcons concept search
  14. 14. http://blissfullydomestic.com/2010/spring-clean-your-blog-comments Extraction - matching dirty data
  15. 15. Linking Library data already contain links
  16. 16. Links to resources identified by code values
  17. 17. Links to classification notations
  18. 18. Links to persons
  19. 19. Links to geographical entities and institutions
  20. 20. „Outsourcing“ authorities  DBPedia  VIAF  Geonames
  21. 21. http://thesecretmirror.com/linked-data/why-you-should-support-linked-data Crawling data
  22. 22. Distribution  Lightweight API  Single interface to the datasets
  23. 23. http://www.flickr.com/photos/virtualsugar/316200555 Open bibliographic data
  24. 24. Open licences
  25. 25. National Technical Library's library linked data prototype http://www.panoramio.com/photo/20268409  Incomplete  Parallel coexistence with the original way of data distribution
  26. 26. Benefits of linked library data  Readable  Sharable  Linkable  Distributable  Integrable  ?-able
  27. 27. Changes
  28. 28. Questions!
