  1. Yes, we can! • Some observations on library linked data kcoyle@kcoyle.net

  2. What is the answer? kcoyle@kcoyle.net

  3. What is the question? kcoyle@kcoyle.net

  4. What do we do? kcoyle@kcoyle.net

  5. Why do we do it? kcoyle@kcoyle.net

  6. Cataloging Distinguish Differentiate Separate kcoyle@kcoyle.net

  7. Cataloging Distinguish Differentiate Separate kcoyle@kcoyle.net

  8. Is this the same book?OrIs this a different book? kcoyle@kcoyle.net

  9. "Books are a slow conversation" Each one listens to others and talks to others. kcoyle@kcoyle.net

  10. kcoyle@kcoyle.net

  11. Today's tools and models • MARC (at the end of its life)‏ kcoyle@kcoyle.net

  12. Today's tools and models • MARC (at the end of its life)‏ • FRBR (a model, but based on past practices; unstable)‏ • RDA (based on FRBR and AACR and MARC, with some new concepts)‏. kcoyle@kcoyle.net

  13. Where are we going?

  14. Further

  15. Cutter's questions What books does the library have by this author? What books does the library have on this topic? Does the library have a book with this title? kcoyle@kcoyle.net

  16. Tomorrow's questions Starting with this author, what authors are related to him/her through their subject matter? Which are closest to this author? Who else was writing in this time in this place? Given this subject, who are the key authors? kcoyle@kcoyle.net

  17. Day after tomorrow's questions Where does this subject lead me? What resources (library or outside of library)? What are related subjects? Information about the subject (encyclo/wiki/pedia)‏ kcoyle@kcoyle.net

  18. What is further? Semantic web – ending the library data silo Navigation and discovery instead of search Computable data – ability to mine bibliographic data for information.. kcoyle@kcoyle.net

  19. Linking is not destructive kcoyle@kcoyle.net

  20. Reorganize around new entities Persons Subjects kcoyle@kcoyle.net

  21. Entities can interact Persons Subjects kcoyle@kcoyle.net

  22. http://openlibrary.org Open Library kcoyle@kcoyle.net

  23. Everything is connected to something • No (or few) dead ends • Computation is "easy" (e.g. topic maps, term clouds, timelines) ‏ • Users can discover previously unseen connections between information resources.

  24. Back to our tools FR's – FRBR, FRAD, FRSAD RDA kcoyle@kcoyle.net

  25. Perfect, or perfected?Not yet kcoyle@kcoyle.net

  26. FRBR Person Work Corp Expression Event Manifestation Concept Place Item Object kcoyle@kcoyle.net

  27. FRBR Person Work Corp Expression Event Manifestation Concept Place Item Object kcoyle@kcoyle.net

  28. FRBR – bibliographic relationships Work Work Expression Expression Manifestation Item kcoyle@kcoyle.net

  29. http://kcoyle.net/rda kcoyle@kcoyle.net

  30. Some issues - FRBR Not well understood Untested, mostly unimplemented Superceded by FRAD, FRSAD, and now requiring changes to be compatible May not interact well with non-FRBR data. kcoyle@kcoyle.net

  31. More issues - FRBR Group 3 (Subjects) should be replaced with a general subject relationship to anything that can be identified Group 3 elements should be general (e.g. Place) or be subproperties of a more general property Placement of data elements within WEMI is highly debated, especially for collective items (books of essays, multiple music works on a disk)‏. kcoyle@kcoyle.net

  32. FR for Authority Data (FRAD)‏ Person Corp Family

  33. FR for Authority Data Person Identification Corp name Family Controlled access point Rules Agency

  34. FR for Authority Data Person Identification Corp name Family Controlled access point Is basis for Rules using Assigned by Agency

  35. FR for Subject Authority Data(FRSAD)‏ Work FRBR Event Is subject Concept Place Object

  36. FR for Subject Authority Data(FRSAD)‏ Work Thema Has subject Nomen Has name

  37. RDA • RDA is at least 3 things: • Cataloging guidance • Ontology (not entirely "linked data" compatible)‏ • Definition of values (most are text; some controlled lists, but most mix list and text)‏

  38. Some issues - RDA Not well understood Untested, mostly unimplemented Adheres strictly to FRBR - Every RDA element is valid only as a single FRBR entity. kcoyle@kcoyle.net

  39. RDA Properties Extent (Manifestation)‏ Extent (Item)‏ Extent of still image (Manifestation)‏ Extent of still image (Item)‏

  40. Some issues - RDA There is no data carrier defined for RDA. kcoyle@kcoyle.net

  41. RDA in RDF Joint project between DCMI and RDA April, 2007

  42. http://metadataregistry.org • RDA – properties, relationships, controlled values; still provisional • FRBRer - completed • FRAD – in progress • ISBD – in review
