Technical Services (Acquisitions, Cataloging, Collection Development)
Administration Reference Systems Other
How much do you know about FRBR, FRAD, and RDA already? Never heard of them I’ve heard them mentioned, but I don’t know
much about them yet I’ve looked at some of the documentation, but
don’t quite get it I have a pretty good grasp of the models and
looked at some RDA records I’ve created catalog records using RDA
Outline
What is RDA? Why was it developed? History of RDA Influences and foundations The FRBR family of models Objectives and principles Organization and structure
RDA in a nutshell RDA=Resource Description and Access New international cataloging standard to replace
AACR2 Content standard, not display or encoding
standard Designed to apply to resources in any format Greater emphasis on “cataloger’s judgment” (i.e.,
more options and alternatives) Greater emphasis on relationships
Why not just update AACR2?AACR2 has been described as… Difficult to adapt to digital resources Very complex and intricate Little used outside of library profession Some conventions still tied to the catalog card Too Anglo-American centric
Potential benefits of RDA
Based on slides from Barbara B. Tillett, Deutscher Bibliothekartag, Berlin, June 2011, http://www.rda-jsc.org/docs/US-RDA-Test-Deutsche-Bibliothekartag-June-2011rev2.ppt
Based on a data model for a more logical structure
Adds/enhances relationships missing or not fully realized in AACR2
Separates content from carrier Supports data that can play well in the Web
environment and be more easily manipulated by machines
Increased focus on user needs
A brief history of RDA Developed by the
Joint Steering Committee for Development of RDA (JSC)
Began as AACR3 in 2004 Shift in 2005 to RDA New structure of the RDA draft in 2007 to align more
closely with the FR… models Full draft issued for community comment in late
2008 Published in RDA Toolkit (online) in June 2010 U.S. national libraries coordinated a test in late 2010
Announced results and implementation decision June 2011
Earliest implementation (with conditions) January 2013
Influences and foundations
The “FRamily” of models: FRBR (Functional Requirements for Bibliographic
Records) FRAD (Functional Requirements for Authority Data) FRSAD (Functional Requirements for Subject
Authority Data), eventually AACR2 (Anglo-American Cataloguing Rules, 2nd
ed.) Statement of International Cataloguing
Principles ISBD (International Standard Bibliographic Des
cription) (But RDA does not follow ISBD order and ISBD punctuation is no longer required)
RDA’s Predecessors: What Are FRBR and FRAD? Reports written by IFLA subcommittees – the
“FRamily” Answers to perceived user needs An evolving conceptual entity-relationship
model
FRBR and FRAD: The “FRamily”
Functional Requirements for Bibliographic Records
Published in 1998 by the IFLA Study Group on the Functional Requirements for Bibliographic Records
Functional Requirements for Authority DataPublished in 2009 by the IFLA Working Group on Functional Requirements and Numbering of Authority Records
There is a third report, Functional Requirements for Subject Authority Data, published in 2010, but it does not affect RDA (yet?)
FRBR and FRAD: User Tasks
User tasks in FRBR: Find IdentifySelectObtain
User tasks in FRAD: FindIdentifyContextualize (Clarify)Justify (Understand)
FRBR and FRAD:Conceptual E-R Model Conceptual model: high-level, general Entity-relationship model: identifies things and
how they interact with each otherEntitiesAttributesRelationshipsInstances
E-R Diagrams
The E-R Diagram for RDA In the toolkit, this diagram can be found under
the “Tools” tab, Entity Relationship Diagram (ERD), Overview, Relationships
Introducing the Entities
Group 1: Bibliographic Entities Work, Expression, Manifestation, Item
Group 2: Responsibility Entities Person, Family, Corporate Body
Group 3: Subject Entities Concept, Object, Place, Event
FRAD Entities Name, Identifier, Controlled Access Point, Rules, Agency
Group 1 Entities Work
“Distinct intellectual or artistic creation”
Expression “Intellectual or artistic realization of a work…”
Manifestation “Physical embodiment of an expression”
Item “A single exemplar of a manifestation”
Group 2 and Group 3 Entities Group 2: Responsibility Entities
Person: “an individual or an identity established by an individual”
Family Corporate Body
Group 3: Subject Entities Concept, Object, Place, Event Section 4 of RDA covering these entities has not been
developed yet (FRSAD?)
Attributes in RDA (Group 1) Three classes of attributes: Core,
Enhanced, and Specialized Work: Title, Date, Place of Origin, Form Expression: Content Type, Date, Language Manifestation: Publication Statement,
Edition Statement, Extent, Carrier Type, Copyright Date, Series Statement, Numbering of Serials
Item: no core elements; enhanced elements include Restrictions on Access, URL, Preferred Citation
Attributes in RDA (Groups 2 and 3) Person: Name, Fuller Form of Name,
Profession or Occupation, Field of Activity, Title, Date
Family: Name, Place, Prominent Member, Type, Date
Corporate Body: Name, Place, Date, Associated Institution
Group 3 entities: Name, Source Consulted, Status of Identification, Cataloguer’s Note
Relationships in RDA Relationships between the entities
Primary relationships: relationships between Group 1 entities
“Relationships to…”: relationships between Group 1 and Group 2 entities
“Relationships between…”: relationships between instances of entities
Back to User Tasks
So you want a copy of Leaves of Grass? Yes, I want a copy of Leaves of Grass
The user knows the title, maybe the author, which are attributes of a Work
Yes, but I want the Chinese translationLanguage is an attribute of an Expression
Yes, but I want the “deathbed” editionThe user is looking for a particular edition, which is an attribute of a Manifestation
Yes, I want the copy I found the other day with the green cover
This could be considered an “item-specific carrier characteristic”, an Item attribute
Well, I guess, but I’m really looking for something about an electric body???
Example: Wyoming Blue Book WYLDCAT record for the Wyoming Blue Book Possible “FRBRized” display:
Wyoming Blue Book (Work) Print edition, CD edition (Manifestations) Holdings in each library (Item)
Another example: Variations/FRBR Variations/FRBR is a testbed for FRBR,
developed by Jenn Riley and her team at the University of Indiana, Bloomington, focusing on music (primarily classical music): http://www.dlib.indiana.edu/projects/vfrbr/
Prototype catalog, Scherzo
Objectives (from RDA 0.4.2) Responsiveness to user needs (find, identify,
select, obtain, understand) Cost efficiency Flexibility (independent of systems, format,
storage or communication media of data) Continuity (interoperable with legacy data and
other standards)
Principles (from RDA 0.4.3) Differentiation Sufficiency Relationships Representation Accuracy Attribution Common Usage or Practice Uniformity
