rda database implementation scenarios
RDA Database Implementation Scenarios
  • RDA is a content standard
  • RDA is not a display or encoding standard
  • RDA is not prescriptive as to the data structures that are used to create, exchange, store or access the metadata

rda database implementation scenarios7
RDA Database Implementation Scenarios
  • New database structures needed to realise the full potential of RDA
  • Improve efficiency of cataloguing
  • Improve searching and browsing for users
record display
Record Display
  • Unlike AACR, RDA doesn’t specify record display format – it will include examples of RDA data in various display formats
  • This reflects the real world in which display formats are determined by library managers, system designers and system capability
  • Guidelines on ISBD presentation
rda marc working group
RDA/MARC Working Group
  • MARC21 should be neutral regarding FRBR entities and database design
  • The proposals can be found at: http://www.loc.gov/marc/marbi/list-p.html#2008
  • The discussion papers can be found at: http://www.loc.gov/marc/marbi/list-dp.html#2008
marc 21 changes
MARC 21 changes
  • More information about MARC 21 changes early in 2009
  • Relatively minor changes need to support the initial implementation of RDA
  • Mappings of RDA data elements to ISBD, MARC21 and Dublin Core will be included in RDA

dublin core
Dublin Core
  • DCMI/RDA Task Group

    • RDA metadata entities (elements, attributes)
      • E.g. “Title”, “Content type”
    • RDA value vocabularies (terms)
      • E.g. “spoken word”, “microform” (media type)
  • Enable RDA entities to be used in Semantic Web applications/by computers as well as people

bibliographic system changes
Bibliographic system changes
  • Implement support for new/changed MARC 21 data elements:
    • Cataloguing interface
    • Record displays
    • Index definitions
oclc worldcat
OCLC WorldCat
  • Ex-officio member of ALA Committee on Cataloguing
  • JSC RDA Examples Groups
  • RDA/MARC Working Group
  • ALA RDA Implementation Task Force

Libraries Australia
  • Will support the creation and exchange of RDA data from the agreed Australian implementation date
  • Continued support for exchange of AACR2 data
  • Cataloguing policy will allow AACR records to be upgraded to RDA
libraries australia24
Libraries Australia
  • Global change programs to convert AACR records to RDA
  • Provide users with as much notice as possible of the changes to the data format and cataloguing policy
  • Changes will be reflected in training courses and system documentation
  • We aim to provide a training system that supports RDA well in advance of the formal Australian RDA implementation date
