3. FRBR “Family”
Functional Requirements for Bibliographic Records (1998)
 Focus on group 1 entities: work, expression, manifestation,
item
 FRBR
Functional Requirements for Authority Data (2009)

 FRAD
Functional Requirements for Subject Authority Data (2011)
 Focus on group 3 entities: concept, object, event, place, plus
groups 1 and 2
 FRSAD

4. Subject Authority Systems
Known as:
Controlled vocabularies
Structured vocabularies
Concept schemes
Knowledge organization systems

5. Who Uses Subject Authority Data?
Vocabulary creators
Metadata creators
Information intermediaries
End-users

6. User Tasks
Find
Identify
Select
Explore relationships

7. FRSAD’s Relationship to FRBR

8. Definitions
Thema – any entity used as a subject of a work
Nomen - any sign or sequence of signs (alphanumeric
characters, symbols, sound, etc.) that a thema is
known by, referred to, or addressed as

9. FRSAD Conceptual Model
A work can have many themas
A thema may be the subject of many works
A thema may be represented by many nomens
Some works have no themas

10. Thema-to-Thema Relationships
Hierarchical
Partitive
Generic
Instance
Associative

11. Partitive Relationships
Body – Foot, Hand, Head, …
Buildings –Basements, Chimneys,
Garages…
Cells – Cytoplasm, Centrosomes, …

18. FRSAD terms => LCSH
Equivalences = UF (used for)
Associative Relationships = RT (related terms)
Hierarchical Relationships = BT, NT (broader and
narrower terms)
