Database Implementation Scenarios
Record display - ISBD
MARC 21
Dublin Core
Bibliographic system changes
Libraries Australia implementation
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
Scenarios
• New database structures needed to
realise the full potential of RDA
• Improve efficiency of cataloguing
• Improve searching and browsing for users
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
• MARC21 should be neutral regarding
FRBR entities and database design
• The proposals can be found at:
http://www.loc.gov/marc/marbi/listp.html#2008
• The discussion papers can be found at:
http://www.loc.gov/marc/marbi/listdp.html#2008
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
MARC 21 changes
• New subfields for 502 (Dissertation note)
– $b Degree type
– $c Name of granting institution
– $d Year degree granted
– $o Dissertation identifier
– $g Miscellaneous information
MARC 21 possible changes
• New field (tag 011) in the Bibliographic
and Authority formats to identify which of
the FRBR entities is represented by the
record
• 011 ## $aexpression $2rda
MARC 21 possible changes
• A new field in the Bibliographic and Authority
formats for Content Type, Carrier type and
Media type
– 336 $aContent $b Media $cCarrier
• Or separate fields for each
– 336 Content type
– 337 Media type
– 338 Carrier type
• 336 ## $aperformed music $baudio $caudio disc $2rda
MARC 21 possible changes
• New subfields for 340 (Physical medium)

and Non-projected graphics (007/04)

(007/02), Non-projected graphic (007/06) and Tactile materials
(007/10)
– Additional character position for Videorecordings (007/09)
– Additional code for surround sound in Motion picture (007/08),
Videorecording (007/08) and Sound recording (007/04)
MARC 21 possible changes

046 Special coded dates
621 Additional places
622 Address
623 Field of activity

628 Associated language
MARC 21 possible changes
• Possible expansion of the MARC relator
list to include additional roles identified in
RDA
• Support URIs for relator data
• Addition of subfield $4 (Relator code) to
the Authority format
Dublin Core
• DCMI/RDA Task Group
• RDA Element Vocabulary
– 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
• DC Application Profile for RDA
Bibliographic system changes
• Implement support for new/changed
MARC 21 data elements:
– Cataloguing interface
– Record displays
– Index definitions
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 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
