  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. Evolution of the Catalog Book catalogs Card catalogs Online catalogs Same data kcoyle@kcoyle.net

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

  13. Where do we need to go?

  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)‏ Persons and institutions related to the subject. kcoyle@kcoyle.net

  18. Seeking books, or seeking knowledge? BOTH! But users have learned to come to the library only to seek books. kcoyle@kcoyle.net

  19. Where we could go Semantic web – to interact with data from other communities, ending the library data silo Navigation and discovery for users that takes better advantage of the data and leads users to new discoveries Computable data – ability to mine bibliographic data for information Expansion of library data through discovery of new communities of interest. kcoyle@kcoyle.net

  20. kcoyle@kcoyle.net

  21. Similarities are as important as differences Where do we find the similarities in library data? Answer: in authoritative headings; in controlled lists, in fixed (data) fields; in some text fields kcoyle@kcoyle.net

  22. Could we reorganize around similarities? Persons Subjects kcoyle@kcoyle.net

  23. Could we reorganize around similarities? Persons Subjects kcoyle@kcoyle.net

  24. Could we reorganize around similarities? Persons Subjects kcoyle@kcoyle.net

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

  26. 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.

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

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

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

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

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

  32. Some issues - FRBR Not well understood Untested, mostly unimplemented Superceded by FRAD, FRSAD, and now requiring changes to be compatible Group 1 (WEMI) may impede interaction with non-FRBR-ized metadata. kcoyle@kcoyle.net

  33. 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

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

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

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

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

  38. Some issues - RDA • Not well understood • Untested, mostly unimplemented • Adheres strictly to FRBR (which may be undergoing changes)‏ • Every RDA element is valid only as a single FRBR entity. kcoyle@kcoyle.net

  39. RDA Properties Work Manifestation titleOfWork titleProper

  40. RDA Properties Work Manifestation titleOfWork titleProper Expression language

  41. RDA Properties Work Manifestation creator title Expression

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