AACR2 to RDA
AACR2 deconstructed new concepts
new structure
new vocabulary
some new instructions
some changed instructions

Reconstruction into RDA
• every word has changed
• many instructions show visible continuity with AACR2

Focus on the user
0.0
• RDA provides a set of guidelines and instructions on formulating data to support resource discovery.
• The data created using RDA to describe a resource are designed to assist users performing the following tasks:
![Page 9: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/9.jpg)
User tasks
Bibliographic data
• Find• Identify• Select• Obtain
Authority data
• Find • Identify• Clarify• Understand
![Page 10: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/10.jpg)
Consistent focus on the user
Throughout RDA:
data why include this data?
to support the user in completing one of the user tasks
![Page 11: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/11.jpg)
Functional objectives
• RDA divided into 10 sections
• Each section begins with general guidelines
• Functional objectives and principles specific to the section
• Functional objectives =
the data (recorded or formulated according to the instructions in that section)
the user tasks
![Page 12: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/12.jpg)
Example from Section 1
Section 1= Recording attributes of manifestations & items
1.2 Functional Objectives and Principles
The data describing a manifestation or item should enable the user to:
a) find manifestations and items that correspond to the user’s stated search criteria
b) identify the resource described …
c) select a resource that is appropriate to the user’s requirements with respect to the physical characteristics of the carrier and the formatting and encoding of information stored on the carrier
d) obtain a resource …
![Page 13: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/13.jpg)
RDA never lets you forget
• introduction begins with focus on user and user tasks
• functional objectives in each section
• instructions open to cataloguer judgment within the parameters of enabling the successful completion of user tasks
for example, from 3.7 Applied material
Record the applied material used in the resource if it is considered important for identification or selection …

Relationships• link between one entity and another
• basis for navigation and support collocation
• primary relationships: between work, expression, manifestation and item
• 3 other major types of relationships:1. between a person, family or corporate body and a resource
2. between one resource and another resource
3. between a person, family or corporate body and another person, family or corporate body

Primary Relationships
17.4 Recording Primary RelationshipsPrimary relationships are the relationships between a
work, expression, manifestation, and item that are inherent in the FRBR definitions of those entities:
a) the relationship between a work and an expression through which that work is realized
b) the relationship between an expression of a work and a manifestation that embodies that expression
c) the relationship between a manifestation and an item that exemplifies that manifestation

Organization and Structure of RDA
scope of RDA:
bibliographic data authority data
RDA aligned with FRBR and also aligned with FRAD
influence of FRAD: person, family, corporate body, place role of identifiers relationship between name +
entity
![Page 35: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/35.jpg)
Person in RDAdefinition of person influenced by FRAD:
person = an individual or an identity established by an individual (either alone or in
collaboration with one or more other individuals)
scope of 9.0 = persons include fictitious entities
for example works created by fictitious characters: Miss Piggy, Snoopy relationship of person (bibliographic identity) to person
(individual) designate relationship as “real identity” or “alternate identity”

Principles2009 Statement of International Cataloguing Principles2009 final text of RDA including objectives & principles
ICP and RDA developed in sync0. 4.1 ICP “informs” RDA principles
no. 1 for ICP and RDA = Responsiveness to User Needs(RDA)
Convenience of the User(ICP)
![Page 38: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/38.jpg)
RDA Objectives & Principles
Objectives• responsiveness to user
needs
• cost efficiency
• flexibility
• continuity
Principles• differentiation
• sufficiency
• relationships
• representation
• accuracy
• attribution
• common usage or practice
• uniformity
![Page 39: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/39.jpg)
Role of Objectives & Principles
• instructions must be defensible + not arbitrary• real impact on the content of RDAfor example
objective = flexibilityThe data should function independently of the format, medium, or system used to store or communicate the data. They should be
amenable to use in a variety of environments.
result = RDA is a “content standard”
![Page 40: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/40.jpg)
RDA as a Content Standard
“what data should I record?”
RDA can be encoded using different encoding schema
e.g. MARC 21, MODS, Dublin Core, etc.
RDA data can be displayed using different display conventions
e.g. ISBD, label display, etc.
![Page 41: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/41.jpg)
RDA as a Content Standard
implement in our current library environment
use in different metadata communities
ready to be used in newly emerging database structures
ready to be used in the future web environment
![Page 42: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/42.jpg)
Role of Objectives & Principles
for exampleprinciple = representation
The data describing a resource should reflect the resource’s representation of itself.
result = impact on instructions about transcription
2.5.1.4 Recording Edition StatementsTranscribe an edition statement as it appears on the source of information. no instruction to use abbreviations transcribe what is on the source of information

Day 1 of Implementation
implementation in MARC 21 environment
continue with ambiguity
many RDA elements will map to one MARC subfield

Data Elements each element has the potential to be usable:
to indexto searchto build meaningful displays of data
data in element can be used by humans and machines can be used reliably to search or to limit a search can be used for automated processing can be used to generate a meaningful display

Core Elements
many new elements but don’t have to use them all
core elements
not a level of description
core elements are a minimum “a floor, not a ceiling”
must include any additional elements required to differentiate the resource or entity from a similar one
inclusion of other elements is discretionary
![Page 54: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/54.jpg)
Core Elements core elements support a subset of user tasks
• identify and select a manifestation• identify works and expressions embodied in a
manifestation• identify the creator or creators of a work• find a person, family, or corporate body associated with
a resource• identify a person, family, or corporate body
summary of core elements in introduction: 0.6
general guidelines for each section: core elements

Core Elements certain elements are flagged as “core”
title properdesignation of editionpreferred name for the person
certain elements are flagged as “core if” date of distribution if date of publication not identifiedextent if resource is complete or if the total extent is
known element is core but can omit some data
place of publication (if more than one, only the first)

Extensible Framework framework to describe all known resources framework that can be extended to describe
resources yet to be developed
![Page 57: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/57.jpg)
Extensible Framework
many data elements – each precisely defined
data elements can be used in any combination
clear distinction between content and carrier
work contentexpression content
manifestation carrieritem carrier
![Page 58: The framework:structure principles basic concepts Chris Oliver for RDA Workshop June 2010 June 2010](https://reader038.vdocuments.us/reader038/viewer/2022110116/5519f12555034646588b4694/html5/thumbnails/58.jpg)
Extensible Framework
room for growth with framework of attributes and relationships
RDA framework can describe
any content any carrier
in addition, framework for categorizing resources

Categorization of Content & Carrier
RDA/ONIX frameworksupport needs of libraries and publishing industryhelp user to select appropriate resource
What is the categorization framework? consists of 3 elements that can be used in
multiple combinationseach element has controlled vocabulary replaces the GMD

Categorization of Content & Carrier
consists of three elements: content typemedia type
carrier type can use as many of each type as needed media is not core because it can be inferred from
carrier type to record content, media and carrier types not a display standard code all three to support better automated
processing (absence of data = ambiguous data)
