Introduction
• 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
Flat file database structure
Bibliographic record
Holdings/Item record
Name-TitleAuthority record
NameAuthority record
Linked Bibliographic and Authority Records
Bibliographic record
Holdings/Item record
Name-TitleAuthority record

Relational / object-orientated database structure

Access Point Control Record
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
ISBD punctuation example
ISBD Area / Element Punctuation RDA Element
1. Title and statement of responsibility area
1.1. Title proper 2.3.1 Title proper
1.2. General material designation [ ] 3.2 Media type
6.10 Content type
1.3. Parallel title = 2.3.2 Parallel title
1.4. Other title information : 2.3.3 Other title information
1.5. Statements of responsibility
First statement / 2.4.1 Statement of responsibility relating to title
Subsequent statement ; 2.4.1 Statement of responsibility relating to title
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
• 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)– $j Generation– $k Layout– $l Color– $m Foliation– $n Font size– $o Polarity– $p Reduction ratio– $q Digital file encoding format– $r Presentation format for motion picture– $2 Source of controlled terms
MARC 21 possible changes
• New subfield for 500 (General note)– $i Display text– 500 ## $iMount:$aMounted on starched linen– 500 ## $iSource of title proper:$aCaption title
MARC 21 possible changes
• Controlled lists of terms and coded data– Additional codes for types of Non-projected graphics (007/01)– Additional codes for format of Music (008/20)– Additional codes for primary support materials for Maps, Globes
and Non-projected graphics (007/04)– Additional character position for Text (007/02), Notated Music
(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
• New fields in the Authority format to record additional information:– 046 Special coded dates– 621 Additional places– 622 Address– 623 Field of activity– 624 Affiliation– 625 Occupation– 626 Gender– 627 Additional information about a family– 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
