1. Introduction to RDA

RDA stands for Resource Description and Access. It is an international standard for creating structured bibliographic and authority metadata about resources and the entities associated with them.

RDA succeeded AACR2 and was designed to provide a more flexible framework for describing both traditional and digital resources. The original e-PG Pathshala module describes RDA as a successor to AACR2 and emphasizes its suitability for both analogue and digital resources, compatibility with online catalogues and adaptability to emerging database structures.

RDA is particularly important because modern libraries no longer describe only printed books. Library collections now include e-books, websites, databases, streaming media, digital photographs, datasets, sound recordings, moving images, electronic journals and other digital objects.

Therefore, RDA moves cataloguing away from a model designed primarily around the traditional card catalogue and towards a metadata environment capable of supporting online discovery, relationships and linked-data applications.

2. What is RDA?

RDA can be understood as a set of guidelines, instructions, data elements and vocabularies used to create metadata describing library and cultural heritage resources.

The current RDA Toolkit describes RDA as a package of data elements, guidelines and instructions for creating library and cultural heritage resource metadata that is well formed according to international models and intended for user-focused linked-data applications.

RDA is therefore more than a simple replacement rulebook for AACR2. It is a metadata standard designed to describe entities, their attributes and the relationships between those entities.

RDA in simple words

AACR2 mainly asks: How should this bibliographic description be constructed?

RDA additionally asks: What entity is being described, what attributes identify it, and how is it related to other entities?

This distinction is extremely important for understanding the movement from traditional cataloguing to modern metadata and linked-data environments.

3. Why was RDA Developed?

AACR2 was developed in an environment dominated by physical collections and card catalogues. With the growth of computers, online public access catalogues, digital resources, electronic publications and networked information systems, limitations of the older cataloguing environment became increasingly apparent.

The 1997 International Conference on the Principles and Future Development of AACR, held in Toronto, examined the future direction of AACR. Important issues included FRBR, content versus carrier, internationalization and seriality.

The conference demonstrated that incremental revision of AACR2 might not be sufficient for the emerging digital environment. A fundamental rethinking of the cataloguing code was therefore considered necessary.

5. AACR2, AACR3 and RDA: The Important Sequence

Exam trap: RDA is not AACR3. RDA is a new cataloguing and metadata standard that developed from the revision process associated with AACR but adopted a substantially different conceptual and technological orientation.

6. Purpose of RDA

The fundamental purpose of RDA is to provide guidelines and instructions for creating data that support resource discovery.

The Four Classic FRBR User Tasks

Memory trick: FISO = Find – Identify – Select – Obtain.

The original RDA material also discussed additional tasks associated with authority data: Find, Identify, Clarify and Understand.

7. Scope of RDA

RDA is intended to describe a very broad range of resources and entities. It is not restricted to printed books.

• Printed books
• E-books
• Electronic journals
• Websites
• Databases
• Maps
• Music resources
• Sound recordings
• Moving images
• Photographs
• Digital files
• Continuing resources
• Integrating resources
• Other cultural heritage resources

The underlying objective is to create metadata that can operate across different technological environments rather than being dependent upon one particular physical format or catalogue technology.

8. Conceptual Foundations of RDA

The original RDA was strongly associated with three major conceptual and policy foundations:

1. FRBR – Functional Requirements for Bibliographic Records
2. FRAD – Functional Requirements for Authority Data
3. Statement of International Cataloguing Principles (ICP)

These are extremely important for UGC NET and other Library Science examinations.

9. FRBR and RDA

FRBR stands for Functional Requirements for Bibliographic Records.

FRBR provided a conceptual model based on entities, attributes and relationships. It identified four major user tasks: Find, Identify, Select and Obtain.

FRBR also introduced the famous four-level bibliographic entity group:

Work

A distinct intellectual or artistic creation.

Example: The intellectual creation represented by a particular novel.

Expression

The intellectual or artistic realization of a work.

Example: English text, Hindi translation or an audio performance of the same work.

Manifestation

The physical or digital embodiment of an expression.

Example: A particular edition published by a particular publisher in a particular year.

Item

A single individual exemplar of a manifestation.

Example: The copy of a book physically held by a particular library.

10. Easy Example of WEMI

Exam memory: WEMI = Work → Expression → Manifestation → Item.

11. FRAD

FRAD stands for Functional Requirements for Authority Data.

FRAD provides a conceptual framework for analysing the functional requirements of authority data needed for authority control and international sharing of authority data.

Authority data helps users and cataloguers distinguish between entities with similar names and establish relationships among names, persons, families and corporate bodies.

In simple terms:

Bibliographic description tells us about resources.

Authority control helps establish and control the identities and names associated with resources.

12. Statement of International Cataloguing Principles

The Statement of International Cataloguing Principles, developed through the IFLA Meetings of Experts on an International Cataloguing Code, influenced the principles underlying RDA.

The catalogue should help users:

• Find a single resource.
• Find sets of resources related to the same work.
• Find resources embodying the same expression.
• Find resources exemplifying the same manifestation.
• Find resources associated with a person, family or corporate body.
• Find resources on a particular subject.
• Identify a resource or agent.
• Select an appropriate resource.
• Obtain or access the resource.
• Navigate among bibliographic and authority data.

13. Original RDA Structure: Important for Historical and Examination Questions

The e-PG Pathshala module presents the original RDA structure as 10 sections, 37 chapters, 12 appendices, a glossary and an index.
