I examine user tasks and their related issues in the model that reflects Resource Description and Access (RDA) directly, which complements prior studies that dealt mainly with entities and their attributes and relationships. First, the definitions of user tasks in Functional Requirements for Bibliographic Records (FRBR), Functional Requirements for Authority Data (FRAD), and RDA, respectively, are reviewed. Then, mappings between attributes and relationships of the RDA entities to the user tasks are proposed for the RDA-based model; the mapping covering Group 1 and 2 entities, and that for the other entities. The resultant RDA mappings and those shown in FRBR and FRAD are compared, which reveals the superiority of the former mappings.
