Internet
Catalogs are no longer the end points in isolation Global access to data
Integrate bibliographic data with wider Internet environment Share data beyond institutions

“Bridge” Period
Mapping tables for RDA and MARC, Dublin Core, MODS/MADS, and ISBD
Decisions in PCC and local choices for alternatives and options, if needed – documented in RDA Online
Development of RDA Workflows and other training materials (e.g., changes from AACR2)

Data Value Registriesfor Controlled Vocabularies
Categories of entities FRBR: work, expression, manifestation, item,
person, family, corporate body, concept, object, event, place
Values for attributes, e.g.: Work-Expression content types (RDA/ONIX) Manifestation carrier types: (RDA/ONIX) Concepts: (LCSH subject heading strings)
Registries on the Web

RDA Cataloging Scenarios
Scenario 1: Relational/object oriented database
structureAlternative/ future: linked data,
semantic web structuresScenario 2
Linked bibliographic and authority records
Scenario 3‘Flat file’ (no machine-actionable
links)

“Record” structuresBibliographic entry in book
catalogsMain entry/added entries in card
catalogBibliographic, Authority, and
Holdings records – MARC format • Stand alone or linked
Information packets/Description sets = clusters of attributes to identify each entity and indicate relationships• Linked

Information packages
Linked dataAttribute sets (define the
entities and relationships)RDA elements and sub-
elements
Registries Values for controlled dataRelationship designators
25
Wish List
Templates or RDA Online workflow “wizards”
ILS links from specific elements in input screens to RDA instructions
26
Wish List
Import descriptive metadataPublisher/author supplied (e.g.,
ONIX)Third-party supplied
Book vendors, contractorsValidation of required “core”
elements linked to mode of issuance
27
Wish ListImport controlled metadata
VIAF (language/script appropriate to user)
Registries for RDA/ONIX termsDrop down menus for
controlled vocabulariesMedia, content, carrier typesNames of persons, families,
corporate bodiesSubject headings
28
Wish ListAutomatic suggestion of
classification/subject headings for worksBased on keywords found in
resource record and/or digital resource itself or accompanying tables of contents, abstracts, summaries, etc.
Based on matches with existing similar works
Classification and subject heading correlations
29
Wish List
Automatic generation of work/expression data and links to “creator”Based on identifying elements for
the “first” manifestationAutomatic prompting and
validation of work/expression dataSuggests possible matches for
new cataloging
30
Wish List
Easy way to share “maintained” data worldwide
31
Wish ListFRBR collocating (expand
and collapse elements for displays)
Simple displays of pathways to related resources and information about related entitiesOpen options if user wishes
to explore – don’t overwhelm with all possible relationships
Considerations to get there
BridgeWhat incentives are needed to reach
Scenario 1?How would staff of different
institutions, programs, publishers, systems, national, etc., function in and support Scenario 1?
What are the economic/legal obstacles to overcome if some controlled vocabularies are proprietary, restricted, or less easily available on the Web?
Does someone need to start the ball rolling for Scenario 1? Who? How?
