Metadata quality and FRBRization of MARC
What metadata quality issues are of concern in the migration of metadata to new models (e.g. FRBR)
How do computational techniques compare to expert cataloger FRBR application?
Group 1 Entities
Work: a distinct intellectual or artistic creation ; abstract.
Expression: the intellectual or artistic realization of a work ; abstract.
Manifestation: the physical embodiment of an expression of a work.
Item: a single exemplar of a manifestation.
Group 1 Entities Hierarchy
A work is realized through an expression, which in turn is embodied in a manifestation, which is exemplified by an item.
FRBR
In 1998, Functional Requirements for Bibliographic Records: Final Report was published by IFLA (International Federation of Library Associations and Institutions)
New conceptual model to represent the “bibliographic universe”. Based on an entity-relationship model.
User tasks are identified (i.e. find, identify, select, and obtain)
Comprised of 10 entities, Arranged into 3 groups.
Research methodology
Use a selected author’s MARC records (Mark Twain)
Have expert cataloger assess work-set relationships
Compare expert assessment with computational FRBR algorithms

Metadata quality assessment
Main quality issue: Lack of description for complex relationships
Model application is expensive in both computer and expert efforts
New data models (LoD) are changing our view of MARC metadata
