IFLA Library Reference Model
{{Short description|Conceptual model of bibliographic information}}
File:IFLA-LRM Overview of Relationships.png
The IFLA Library Reference Model (IFLA LRM) is a conceptual entity–relationship model developed by the International Federation of Library Associations and Institutions (IFLA) that expresses the "logical structure of bibliographic information". It unifies the models of Functional Requirements for Bibliographic Records (FRBR), Functional Requirements for Authority Data (FRAD) and Functional Requirements for Subject Authority Data (FRSAD).{{sfn| Riva| Le Bœuf| Žumer| 2017| pp= 5, 9}} The IFLA LRM is intended to be used as the basis of cataloguing rules and implementing bibliographic information systems.{{Sfn|LSIT|2020|p=|ps=, section "How is IFLA LRM used?"}} It has Library of Congress subject heading number 2017004509.{{Sfn|LCSH|2017|p=}}
Differences from FR-series models
IFLA LRM adds super-classes res ("thing") and agent to facilitate formal relationship definitions.{{Sfn|IFLA|2016|p=1}} Time span and place are entities rather than literal values.
It uses the same Work, Expression, Manifestation, Item (WEMI) model as FRBR Group 1 entities. The FRBR Group 2 corporate body and FRAD family are combined into a single collective agent type. FRBR Group 3 entities are deprecated. A redefined nomen type encompasses name from FRAD plus nomen, identifier, and controlled access point from FRSAD.{{Sfn|IFLA|2016|p=1}}
