Intro to rda

  1. 1. An Introduction to RDA Presented to Mills College Library Staff Anna Enos .. 14 November 2011
  2. 2. What is RDA?
  3. 3. What is RDA? Resource Description and Access New cataloging standard for the digital age Successor to the Anglo-American Cataloguing Rules (AACR) Inspired by:  Functional Requirements for Bibliographic Records (FRBR)  Functional Requirements for Authority Data (FRAD)
  4. 4. What is RDA? A content standard designed to record and describe resources It is NOT a display standard Designed to be compatible with MARC and other encoding and metadata standards
  5. 5. Goals of RDA Flexibility Adaptability Compatibility Enable users to find, identify, select and obtain resources
  6. 6. Why do we need RDA?
  7. 7. Why was RDA created? RDA was created to replace AACR AACR is outdated!  Createdin the 1970s for a print-based environment By 2005 the Joint Steering Committee for the Revision of AACR (JSC) declared AACR no longer viable for the digital age RDA arose out of this need for a new standard to accommodate past, present and future formats and materials
  8. 8. AACR Catalogs
  9. 9. RDA Catalogs
  10. 10. Structure of RDA
  11. 11. Structure of RDA Foundations in FRBR and FRAD FRBR and FRAD are conceptual models  Entity-relationship model  FRBR demonstrates the structure and relationships of bibliographic records  FRAD provides foundation for access points and authority control RDA guidelines incorporate FRBR entities, attributes and user tasks
  12. 12. FRBR and FRAD Terminology User tasks are defined as the need to find, identify, select, and obtain Entities are structured into 3 groups:  Group 1: Work , Expression, Manifestation, Item  Group 2: Person, family, corporate body (those responsible for Group 1 entities)  Group 3: concept, object, event, place (the subject of Group 1 entity)
  13. 13. FRBR and FRAD Terminology Each entity has a series of attributes  Characteristics of the entity RDA incorporates the basic set of attributes as its “core elements” Examples:  work: title or genre  manifestation: publisher, date of publication  item: identifier such as a barcode or RFID tag  person: dates, gender, title
  14. 14. How is RDA Different fromAACR?
  15. 15. How is RDA Different? Built with FRBR/FRAD user tasks rather than focus on materials Different organizational structure  Inspired by FRBR user tasks Divided into two parts:  Sections 1-4: Recording attributes of entities  Sections 6-10: Recording relationships between entities Core elements and alternatives
  16. 16. How is RDA Different? Online Access!  RDA Toolkit is 100% online  Includes full text of AACR2 Designed to be used in automated processing New terminology: works, resources, manifestations
  17. 17. How is RDA Different? No more “Main Entry”  It is now “Access Point” No more abbreviations No more GMD  Replaced by three RDA core elements:  336 Content type (text, sounds)  337 Media type (audio, video, computer)  338 Carrier type (filmstrip, videodisc, card)
  18. 18. How is RDA Different? Controlled Vocabularies Includes both closed and open sets  Allows catalogers to add terms Registered online in the Open Metadata Registry  RegisteredRDA Element Sets and Value Vocabularies Both copyright AND publication dates New MARC fields
  19. 19. New MARC fields in RDA Authority:  Bibliographic:  046 - Special Coded Dates  336 - Content Type  336 - Content Type  337 - Media Type  370 - Associated Place  338 - Carrier Type  371 – Address  New Codes in 007 and 008  372 - Field of Activity  380 - Form of Work (R)  373 – Affiliation  381 - Other Distinguishing Characteristics  374 – Occupation of Work or Expression (R)  375 - Gender  382 - Medium of Performance (R) - additional subfields (under discussion)  376 - Family Information  383 - Numeric Designation of a Musical  377 - Associated Language Work (R) - additional subfields (proposed) Holdings:  384 - Key (NR)  337 - Media Type  338 - Carrier Type  New Codes in 007
  20. 20. Mapping AACR to RDA AACR RDA Main Entry  Preferred Access Author Point Physical Description  Creator General material  Carrier Description designator  3xx fields:  Content type  Media type  Carrier type
  21. 21. RDA Records in the Catalog
  22. 22. RDA Record in Millennium
  23. 23. RDA Record in OPAC
  24. 24. RDA Pros and Cons
  25. 25. RDA Pros Online Access Compatible with metadata schema Allows flexibility International scope Backwards compatible!
  26. 26. RDA Pros
  27. 27. RDA Cons Disappearance of GMD  Confusion for users and catalogers Cost Concerns  Stafftime in training, implementation  Financial cost for user licensing Reliance on MARC
  28. 28. Where is RDA Now?
  29. 29. Where is RDA now? RDA is here! Went “live” in June 2010 with testing period completed in June 2011 Many libraries already using RDA  More than 30,000 RDA records in OCLC  More than 6,000 in Library of Congress OCLC policy: Allow original RDA catalog records Decision to implement made by US National Libraries:  Library of Congress, National Library of Medicine, National Agriculture Library
  30. 30. Decision of US NationalLibraries: Implement RDA after January 2013, contingent on meeting certain requirements:  Rewrite RDA instructions in clear, unambiguous, plain English  Define process for updating RDA in the online environment  Develop full RDA record examples in MARC and other encoding schema  Demonstrate credible progress towards replacement for MARC  Lead and coordinate RDA training
  31. 31. Conclusions
  32. 32. RDA is a work in progress
  33. 33. In the Meantime… Start conversations with staff, ILS, vendors, other libraries  Allow RDA records in the catalog?  Display fields in OPAC?  Launch an RDA cataloging pilot project? Stay current with developments
