  1. RDA and Linked Data Steve Henry University of Maryland March 2, 2013

  2. Encoding RDA Data • One more time: RDA is a content standard not a display standard • It is also not an encoding standard • Examples so far have shown RDA in a MARC environment • But RDA is also designed to be flexible. • Can be encoded in MODS, Dublin Core, etc…. • …and in RDF

  3. The Briefest Intro to RDF That Has Ever Been

  4. RDF -Resource Description Framework • RDF is a Web standard for describing any thing, concept, or relationship • Each thing, concept, and relationship is represented by a globally unique URI • Relationships between these entities are represented by RDA triples in the form: subject, predicate, object • For example…

  8. Linked Data • A set of best practices for • Sharing data • On the Web • In machine-readable form • Four rules • Provide a URI • Make the URI an HTTP URL • Provide interesting information • Link to other URIs so more things can be discovered

  10. Hey. We’re Doing Linked Data!

  11. What about bibliographic records

  12. http://id.loc.gov/authorities/names/n80050147 http://umaryland.worldcat.org/oclc/10262450 http://www.geonames.org/maps/google_40.714_-74.006.html

  13. BIBFRAME • Full name: Bibliographic Framework Transition Initiative • Initiative of the Library of Congress • Essentially a linked data model for library bibliographic data • Potential replacement/supplement for MARC

  14. parodyOf reprintOf Source: http://bibframe.org/vocab/

  15. BIBFRAME • Each instance gets a URI • Relationships between works, instances, authorities, places, recorded • Needs to be harmonized with FRBR—Expressions? • FRBR seen as an abstract model • BIBFRAME is a Web implementation

  16. BIBFRAME Timeline • May 2011: Initiative announced • May 2012. Zepheira contracted • Fall 2012. Use cases tested • November 2012. Bibliographic Framework as a Web of Data (high-level model) • October and December 2012. Face-to-face meetings with early experimenters

  17. Early Experimenters • British Library • Deutsche National BibliotekDNB • George Washington University Library • National Library of Medicine • Princeton Library

  18. Bibliography • https://delicious.com/spurioso/tag_bundle/LinkedData • Great introductory video! • http://www.youtube.com/watch?v=4x_xzT5eF5Q • http://linkeddata.org/ • http://bibframe.org/ • http://listserv.loc.gov/listarch/bibframe.html • http://rdvocab.info/

  19. How Does This All Relate??

  20. Linked Data RDA Discovery MDR BIBFRAME

  21. Some examples of how all this fits together

  22. Rule of Three

  23. Attributes for Persons

  24. Medium of Performance

  25. What to do now?

  26. Talk to vendors • Show them MDR • Ask them what their plans are for L.D. • Follow BIBFRAME development • Bibframe.org • bibframe@listserv.loc.gov • Look for RDA records in your discovery tools • Think about search strategies • Ask a cataloger for help! • Link your data • Discographies, bibliographies, thematic catalogs • Digital Humanities projects

  27. Thanks!
