Functional Requirements: the FRBR Family of Models
The "FRBR family" consists of three conceptual models each covering an aspect of the data recorded in bibliographic and authority records.
The first model was Functional Requirements for Bibliographic Records, published in 1998.
The second was Functional Requirements for Authority Data, published in 2009.
The third is Functional Requirements for Subject Authority Data, which is still in development.
