The 2020 RDA – Where
does it come from?
• A major revision of RDA,
based on
• IFLA Library Reference
Model (2017) = “LRM”

3. RDA New Concepts Series: Representative Expressions and Manifestation Statements February 19, 20203
LRM
• LRM is a consolidation of
• Functional Requirements for
Bibliographic Records (FRBR)
(1997)
• Functional Requirements for
Authority Data (FRAD) (2009)
• Functional Requirements for
Subject Authority Data (FRSAD)
(2010)

The FRBR/LRM bibliographic universe
Attributes
• In the model, entities have attributes (called elements in RDA) that
may be used to describe instances of an entity and distinguish
instances from each other
• At the model level, entities must be defined so that they do not
overlap
• Attributes used to describe one entity cannot be defined for use
with another entity

13. RDA New Concepts Series: Representative Expressions and Manifestation Statements February 19, 202013
So what’s the problem?
• Entity-relationship principles require strict boundaries between
the entities in terms of the attributes that can be used to describe
them
• The new Toolkit is quite clear about what the domain of each
element is
• This is necessitated by requirements of linked data structures
• But people don’t necessarily think of the bibliographical universe
in these terms
• In particular, database users often associate attributes of
expression with works

14. RDA New Concepts Series: Representative Expressions and Manifestation Statements February 19, 202014
So what’s the problem?
• For example, many think of the work Alice’s adventures in
Wonderland as
oA novel
Work element: category of work
oA text
Expression element: content type
oIn English
Expression element: language of expression
oFor children
Expression element (in 2020 RDA): Intended audience
of expression

15. RDA New Concepts Series: Representative Expressions and Manifestation Statements February 19, 202015
So what’s the problem?
• Under current RDA it is inappropriate to include language or content
type in a description (a.k.a. authority record) for a work and under the
2020 text it will be inappropriate to record intended audience because
none of these is (or will be) an element that can be used to describe a
work entity:

400 1_ Carroll, Lewis, ǂd 1832-1898. ǂt Alice in Wonderland

16. RDA New Concepts Series: Representative Expressions and Manifestation Statements February 19, 202016
So what’s the problem?
• Catalogers clearly want to record this type of information in
descriptions of works and they’re not wrong to want to, though current
RDA doesn’t allow it. From the current NAF:

17. RDA New Concepts Series: Representative Expressions and Manifestation Statements February 19, 202017
So what’s the problem?

18. RDA New Concepts Series: Representative Expressions and Manifestation Statements February 19, 202018
The solution:
Representative expression
• New concept introduced with LRM
• Initially one possibility was to choose an expression as the
“representative expression” of a work
• Instead, however, as finally published LRM defined an attribute of
work called representative expression attribute:
“An attribute which is deemed essential in characterizing the work and
whose values are taken from a representative or canonical expression of the
work”

19. RDA New Concepts Series: Representative Expressions and Manifestation Statements February 19, 202019
Representative expression
in 2020 RDA
• RDA has adopted both the concept of representative expression (a
relationship) as well as representative expression attributes (work-
level elements)

Metadata description sets
• New vocabulary for what we have in the past called
“records,” e.g., “authority records for persons,” etc.
• RDA Glossary definition:
• One or more metadata statements that describe and
relate individual instances of one or more RDA
entities.
• A metadata statement is “a piece of metadata that
assigns a value to an RDA element that describes an
individual instance of an RDA entity.”

OK, so how do I do this in

• Good question!
• The MARC Advisory Committee has not yet created coding for
representative expression elements
oUse existing coding?
oUse existing field coding, but define different subfields for representative
expression elements?
oUse entirely different field coding?

Manifestation statements:
Can I do it in MARC?
• The MARC Advisory Committee considered a discussion paper
(2020-DP06) at ALA Midwinter last month about manifestation
statements that is expected to return as a proposal at Annual.
• Manifestation statements will probably be recorded in a newly
defined 881 field, but not clear yet what subfields will be
approved or how manifestation statements will be recorded
within them.
• The discussion paper called for a designated subfield for each
type of RDA manifestation statement.
