Short-cuts An element/property that represents a linked chain of two or more other elements Manifestation has expression manifested has work manifested Expression Work has work expressed Expression not recorded The only short-cut in the original Toolkit 4 RDA Linked Data Forum ALA 2019 March 5, 2021
New short-cuts New Toolkit short-cuts simplify aggregates has contributor agent to aggregate Agent Manifestation has expression manifested Expression has creator agent of expression Aggregated expression not recorded 5 RDA Linked Data Forum ALA 2019 March 5, 2021
Element hierarchies All elements belong to a well-defined and wellformed semantic hierarchy 13 x 13 high-level relationship matrix 13 entities linked to 13 entities Full matrix hierarchy under construction Semantics support “smart” machine-processing of RDA data 6 RDA Linked Data Forum ALA 2019 March 5, 2021
Data inheritance appellation of work related agent of work > related person of work >> creator person of work >>> author person of work >>>> screenwriter person “This presentation” Gordon Dunsire entailment X Data is automatically ‘inherited’ up a hierarchy through semantic inferencing 7 RDA Linked Data Forum ALA 2019 March 5, 2021
Appellation inheritance Person appellation of person > name of person >> preferred name of person appellation of person > access point for person >> authorized access point for person appellation of person > identifier for person 8 RDA Linked Data Forum ALA 2019 Gordon Dunsire, Gordon Dunsire, Gordon nb 2001072552 March 5, 2021
