n. (abbr. RDA)a metadata content standard developed in the library community for the description of library resources, cultural heritage materials, and their related named entitiesNimer 2010, 228RDA is a new library cataloging code developed by the Anglo-American cataloging community. RDA is meant to replace the second edition of the Anglo-American Cataloging Rules, or AACR2, which was first published in 1978. The new code makes some significant changes to cataloging practice and has incorporated recent theoretical advances within the library field. It is also meant to expand the scope of resource description, addressing a wider range of materials and making the descriptions useful in a wider context.Hensen et al. 2011, 13Many of the assumptions underpinning bibliographic data content standards, such as the Anglo-American Cataloging Rules (AACR2) and the recently published Resource Description and Access (RDA), have very limited relevance for archival control/description.Danskin 2011, 2RDA makes a clear distinction between the carrier of a resource, such as a volume, or a videodisc, and its intellectual content, for example, text, or, two-dimensional moving image. RDA also provides comprehensive instructions for recording attributes of persons, families and corporate bodies associated with resources. Future development is planned to extend the scope of RDA to include guidelines and instructions for description and access by subject. RDA defines vocabularies to describe relationships between entities. ¶ Changes from AACR2 that may be of interest to the archival community include: provision of more elements for non-printed text resources, provision of more elements for non-text resources, provision of more elements for unpublished resources, provision to treat families as creators or contributors.Gueguen et al. 2013, 578The FNDL recommends that all cultural heritage use Resource Description and Access (RDA) as a starting point. RDA is a library standard based on FRBR and thus, by extension, is related also to FRBRoo and, by further extension, to CRM.Gracy and Lambert 2014, 98RDA, which was first published in 2010, is the successor to Anglo-American Cataloging Rules (AACR2).
Resource Description and Access is the successor standard to the Anglo-American Cataloguing Rules.
