RDA: Resource Description and Access

  1. 1. RDA: RESOURCE DESCRIPTION AND ACCESS Presenter: Rieta Drinkwine, MLS www.rietadrinkwine.com
  2. 2. WHAT IS RDA? • A content standard – Does not dictate how to display information • Built off of AACR2 and FRBR (+ FRAD) – FRBR = Functional Requirements for Bibliographic Records – FRAD = Functional Requirements for Authority Data (essentially establishes the controlled vocab for authority data)
  3. 3. WHY RDA? • Internationally standardized/Usable – IFLA (International Federation of Library Associations and Institutions) created FRBR & FRAD • Not just books – Accommodates all resources – RDA incorporates the language of cataloging (AACR2) with the broader “semantic” web
  4. 4. FRBR (BACKGROUND) • IFLA initiated an international re-examination of cataloguing theory in 1961 – Main reason for change – automated systems • 1990 – Stockholm Seminar on Bibliographic Records – Realized need to: • Reduce cost of cataloging • “minimal level” cataloging occurring – required closer assessment of user needs http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 1
  5. 5. FRBR (BACKGROUND) • Stockholm Seminar – 9 Resolutions • 1 led to study to define the functional requirements of bibliographic records • Primary objectives of study: – Framework to relate the data recorded in bibliographic records to needs of users accessing those records – Recommend basic level of functionality for records created by national bibliographic agencies http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 2 & p. 7
  6. 6. FRBR (THE STUDY) • What are those functional requirements for users? – – – – Find materials Identify an entity Select an appropriate entity Obtain/acquire described entity http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 7
  7. 7. FRBR • Entity = Key objects of interest to users of bibliographic data (ENTITIES) 3 Groups of Entities Products of intellectual/artistic endeavors Entities responsible for intellectual/artistic content Subjects of intellectual/artistic endeavors Work Person Concept Expression Corporate Body Object Manifestation Event Item Place http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 13
  8. 8. FRBR (ENTITIES) • The entities defined as work (a distinct intellectual or artistic creation) and expression (the intellectual or artistic realization of a work) reflect intellectual or artistic content. • The entities defined as manifestation (the physical embodiment of an expression of a work) and item (a single exemplar of a manifestation), on the other hand, reflect physical form. http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 14
  9. 9. FRBR • A work may be realized through one or more than one expression (hence the double arrow on the line that links work to expression). (ENTITIES) • An expression, on the other hand, is the realization of one and only one work (hence the single arrow on the reverse direction of that line linking expression to work). • An expression may be embodied in one or more than one manifestation; likewise a manifestation may embody one or more than one expression. • A manifestation, in turn, may be exemplified by one or more than one item; but an item may exemplify one and only one manifestation. http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 14
  10. 10. FRBR (EXAMPLES) □ w1 The Wall Street Journal □ e1 the Eastern edition □ m1 the print format of the Eastern edition □ m2 the microfilm of the Eastern edition □ e2 the Western edition □ m1 the print format of the Western edition □ m2 the microfilm of the Western edition http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 23
  11. 11. FRBR (EXAMPLES) □ w1 J. S. Bach’s Six suites for unaccompanied cello □ e1 performances by Janos Starker recorded partly in 1963 and completed in 1965 □ m1 recordings released on 33 1/3 rpm sound discs in 1966 by Mercury □ m2 recordings re-released on compact disc in 1991 by Mercury □ e2 performances by Yo-Yo Ma recorded in 1983 □ m1 recordings released on 33 1/3 rpm sound discs in 1983 by CBS Records □ m2 recordings re-released on compact disc in 1992 by CBS Records http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 23
  12. 12. FRBR (ATTRIBUTES) • Attributes of a Work: Entities have attributes, which are “the means by which users formulate queries and interpret responses when seeking information about a particular entity” http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 31 & p. 33 – – – – – – – – – – – – title of the work form of work date of the work other distinguishing characteristic intended termination intended audience context for the work medium of performance (musical work) numeric designation (musical work) key (musical work) coordinates (cartographic work) equinox (cartographic work)
  13. 13. FRBR • Many terms signal the type of relationship between entities (RELATIONSHIPS) that should be indicated by the cataloguer – i.e., edition, version, based on, translated from, etc. • Wide range of relationship types – In a Work-to-work relationship: sequel = successor, Teacher’s guide = a supplement, etc. http://archive.ifla.org/VII/s13/frbr/frbr_2008.pdf p. 55
  14. 14. FRBR & RDA • FRBR + FRAD shape how we view bibliographic records – Especially the controlled vocabulary • RDA provides a “Stronger emphasis on helping users find, identify, select and obtain” and “supports clustering of bibliographic records to show relationships between works and their creators.” (according to official RDA brochure) http://www.rda-jsc.org/docs/rdabrochureJanuary2010.pdf
  15. 15. FRBR & RDA • RDA is: Entity  Element  attribute http://www.rda-jsc.org/docs/5rda-elementanalysisrev3.pdf – The relationship is represented by the “Element” (“attributes and relationships associated with a resource or other entity are formally represented in RDA as elements”) – An RDA element usually corresponds to an attribute or relationship as defined in FRBR and FRAD • Example: RDA Title element = FRBR attribute title of manifestation
  16. 16. RDA (KEY TERMS) • Resource – identifiable information object (either tangible or intangible) • Resource Discovery – Find, Identify, Select, Obtain • Descriptive Data – reflects attributes and relationships associated with the Entities work, expression, manifestation, and item (as defined by FRBR) • Access Point Control Data – reflects attributes and relationships associated with the entities person, family, corporate body place, work and expression as defined by FRAD – Access points are referred to as “main” or “added” entries in AACR2 http://www.rda-jsc.org/docs/5rda-scoperev4.pdf
  17. 17. BRIEF TANGENT: MARC 0XX = Control information, numbers, codes 1XX = Main entry 2XX = Titles, edition, imprint 3XX = Physical description, etc. 4XX = Series statements 5XX = Notes 6XX = Subject access fields 7XX = Name, etc. added entries or series; linking 8XX = Series added entries; holdings and locations 9XX = Reserved for local implementation 100 - Main Entry - Personal Name 110 - Main Entry - Corporate Name 245 - Title Statement 250 - Edition Statement 257 - Country of Producing Entity 264 - Production, Publication, Distribution, Manufacture, and Copyright Notice http://www.loc.gov/marc/bibliographic/

  19. 19. RDA • March 31, 2013 • Emphasis on “what you see” (IMPLEMENTATION) – Attempt to save cataloguers time by minimizing editing – Avoids abbreviations used by AACR2 http://www.rda-jsc.org/docs/rdabrochureJanuary2010.pdf Examples: AACR2 RDA 2nd ed. Second edition. Denver, CO Denver, Colorado ill. illustrations
  20. 20. SUMMARY! • RDA (Resource Description and Access) is based on FRBR & FRAD, as defined by IFLA. • Goals – make cataloging easier by taking what you see – Accommodate a wide range of resources – Create more user friendly catalogs – Expand outside of realm of libraries • Follows concepts of Semantic web and RDF (resource description framework), which follows the same principle of triples http://cheminfov.informatics.indiana.edu:8 080/yuysun/hychembiospace.html
