enhanced description Base elements derived from AACR2 and MARC 21 Additional descriptive elements ―Content type, Media type, Carrier type ―Resolution, Regional encoding, Transmission speed Specific identification of “buried” elements ―Nature of the content, Coverage of the content, Accessibility content

controlled vocabularies Incorporates controlled vocabularies derived from AACR2 and MARC 21 Additional controlled vocabularies ―Content type, Media type, Carrier type ―Form of musical notation, Form of notated movement ―Production method, Encoding format Potential for automated “translation” and “customization” of vocabularies

extended access Elimination of “rule of three” ―No limit to access points for creators, contributors, etc. ―No limit to access points for works contained in a compilation “Unbundling” of elements within access points ―Potential for use as searchable elements or search limiters ―Potential for customization of access points

relationships Elements defined specifically to record relationships ―Adds meaning to conventional “added entry” ―Clarifies identity of related entity Relationship designators ―Indicate specific nature of the relationship ―Potential for use as searchable element or as search limiter ―Potential for use in organizing results sets

web-accessible data Coordination with DCMI ―Alignment with W3C and DCMI models ―Registration of RDA element set and vocabularies Coordination with ONIX ―Development of RDA/ONIX Framework for Resource Categorization

summing up RDA as a metadata standard ―Comprehensive element set ―Flexible and extensible framework ―Well-formed metadata Exploiting the potential ―User-focussed implementation ―Migration to newer database management systems ―Enhancements to applications software
