RDA was created in response to complaints about the Anglo-American Cataloguing Rules, especially the call for a more international, principle-based content standard that takes the perspective of the conceptual models of FRBR (Functional Requirements for Bibliographic Records) and FRAD (Functional Requirements for Authority Data). The past and ongoing process for continuous improvement to RDA is through the Joint Steering Committee for Development of RDA (known as the JSC) to make RDA more international and principle-based.
