Transition Mappings: User Tasks, Entities, Attributes, and Relationships in FRBR, FRAD, and FRSAD mapped to their equivalents in the IFLA Library Reference Model

These detailed mappings of the user tasks, entities, attributes and relationships from the three FR models (FRBR: Functional Requirements for Bibliographic Records, FRAD: Functional Requirements for Authority Data, and FRSAD: Functional Requirements for Subject Authority Data) to the IFLA Library Reference Model (IFLA LRM) facilitate the transition between the models. Starting with an alignment of the respective FRBR, FRAD, and FRSAD elements, the mappings document the resulting disposition of those elements in IFLA LRM. Elements may have been retained, merged, generalized, remodeled, or deprecated. The document starts with a concise overview of the differences between IFLA LRM and the three superseded FR models. It serves as a companion document to IFLA LRM.
