Development history

RDA was originally a partial implementation of each of three conceptual models that were developed separately by the International Federation of Library Associations and Institutions (IFLA):

  • Functional Requirements for Bibliographic Records (FRBR)
  • Functional Requirements for Authority Data (FRAD)
  • Functional Requirements for Subject Authority Data (FRSAD)

The models were consolidated into the IFLA Library Reference Model (LRM) to resolve inconsistencies between the three separate models.

The RDA implementation avoided inconsistencies by retaining aspects of the Anglo-American Cataloguing Rules that were its predecessor.

The RDA Toolkit Restructure and Redesign (3R) Project reviewed and developed the original RDA entities, attributes, and relationships to bring them into full compliance with the LRM.

The RDA archaeology section of the RDA Registry provides tools for identifying and reconciling older versions of the RDA Vocabularies.
