Functional Requirements for Authority Data

Functional Requirements for Authority Data is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Functional Requirements for Authority Data rather than just read about it. In short: Functional Requirements for Authority Data (FRAD), formerly known as Functional Requirements for Authority Records (FRAR), is a conceptual entity-relationship model developed by the International Federation of Library Associations and Institutions (IFLA) for relating the data that are recorded in library authority records to the needs of the users of those records and facilitate and sharing of that data.

Key takeaways

Functional Requirements for Authority Data belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Functional Requirements for Authority Data to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Functional Requirements for Authority Data from memory before moving on to harder problems.

Reference excerpt

Functional Requirements for Authority Data (FRAD), formerly known as Functional Requirements for Authority Records (FRAR), is a conceptual entity-relationship model developed by the International Federation of Library Associations and Institutions (IFLA) for relating the data that are recorded in library authority records to the needs of the users of those records and facilitate and sharing of that data. The draft was presented in 2004 at the 70th IFLA General Conference and Council in Buenos Aires by Glenn Patton. It is an extension and expansion to the FRBR model, adding numerous entities and attributes. The conceptual work and future implementations are aimed at supporting four tasks, frequently executed by users in a library context—either the library patrons (the first three tasks), or the librarians themselves (all four tasks):

Find: Find an entity or set of entities corresponding to stated criteria; Identify: Identify an entity; Contextualize: Place a person, corporate body, work, etc. in context; Justify: Document the authority record creator's reason for choosing the name or form of name on which an access point is based. Next to the development of FRAR, the Working Group on Functional Requirements and Numbering of Authority Records (FRANAR) is also charged to study the feasibility of an International Standard Authority Data Number (ISADN) and serve as the official IFLA liaison to and work with other interested groups concerning authority files.

Worked examples

Example 1 — a first encounter with Functional Requirements for Authority Data

Start with the simplest possible case. Write down what Functional Requirements for Authority Data claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Functional Requirements for Authority Data before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Functional Requirements for Authority Data ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Functional Requirements for Authority Data

In research: Functional Requirements for Authority Data appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Functional Requirements for Authority Data in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Functional Requirements for Authority Data is common in secondary-school and first-year university syllabi. It links to neighbouring topics Library 2.0, Library and information science stubs, Library cataloging and classification, so understanding it makes those chapters shorter.
In everyday life: Look for Functional Requirements for Authority Data outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
