n. (abbr. FRAD)a conceptual entity–relationship model that relates name authority data to user needsCoyle 2012, 42In the FRBR family, Functional Requirements for Authority Data (FRAD) covers the area of name authority. The terms of this vocabulary have been provisionally registered in the Open Metadata Registry. . . . Note that as with other members of the IFLA Functional Requirements family, the elements include descriptors as well as terms for relationships between described entities.Hyvönen 2012, 47Functional Requirements for Authority Data (FRAD), formerly known as Functional Requirements for Authority Records (FRAR), extends the FRBR model above by 1) adding attributes for actors and relationships among actors, 2) by new relationships between actors and their appellations, and 3) telling how information relating to actors is managed by libraries.Tosaka and Park 2013, 652As a practical application of the underlying FRBR and FRAD models, RDA is intended to provide a flexible and extensible framework that is easily adaptable to accommodate all types of content and media within rapidly evolving technology environments, while also producing well-formed data that can be shared easily with other metadata communities in an emerging linked data environment.IFLA 2013, 1The primary purpose of this conceptual model [FRAD] is to provide a framework for the analysis of functional requirements for the kind of authority data that is required to support authority control for the international sharing of authority data. The model focuses on data, regardless of how it may be packaged (e.g., in authority records).Gilliland 2014a, 115FRAD, published in 2009, is a conceptual model that extends FRBR by addressing the attributes of, and relationships between, “various entities that are the centre of focus for authority data (persons, families, corporate bodies, works, expressions, manifestations, items, concepts, objects, events, and places), the name by which these entities are known, and the controlled access points created by cataloguers for them.”
In 2009, the IFLA Working Group on Functional Requirements and Numbering of Authority Records (FRANAR) published the first report on Functional Requirements for Authority Data (FRAD).FRAD, along with Functional Requirements for Subject Authority Data (FRSAD), derive from and expand on Functional Requirements for Bibliographic Records (FRBR), developed by the International Federation of Library Associations and Institutions (IFLA) in 1998. These three models are also known as the Functional Requirement (FR) family of conceptual models.
