RDA: Resource Description and Access is a package of data elements, guidelines, and instructions for creating library and cultural heritage resource metadata that are well-formed according to international models for user-focused linked data applications.
RDA was created by the RDA Steering Committee (formerly the Joint Steering Committee for the Development of RDA) as part of its strategic plan (2005-2009) to replace the Anglo-American Cataloguing Rules, 2nd Edition Revised, which were first published in 1978.
RDA continues to be developed and improved in a collaborative process led by the RDA Steering Committee. RSC gratefully acknowledges the contributions of the many institutions and individuals who have generously given their time and energies to the creation of RDA.
RDA was developed in line with a set of objectives and principles which are informed by the Statement of International Cataloguing Principles. Read RDA Objectives and Principles
