A structural approach to Resource Description and Access (RDA) standards with emphasis on its basic models: functional requirements for bibliographic records and functional * requirements for authority data

RDA (Resource Description and Access) is the new standard for resource descrip¬tion and access designed for the digital world. This new standard is superseding the Anglo-American Cataloguing Rules 2 (AACR2) and attempts to address the chal¬lenges of the new age of information and to develop new rules for description of and access to modern media and the resources available in databases. The increas¬ing tendency in libraries and information centers to include digital resources makes familiarity with the new rules like RDA necessary. In the present paper a brief in¬troduction of this standard and its requirements and goals are presented, followed by a comprehensive evaluation of the structure of this model and its foundations: Functional Requirements for Bibliographic Records (FRBR) and Functional Re¬quirements for Authority Data (FRAD). In addition, the main differences between RDA and AACR2 have been surveyed.
