Gordon Dunsire
Presented to SAC meeting, ALA
Midwinter, Chicago, 2 Feb 2015
Overview
 The JSC agreed at its meeting in Washington, D.C.,
November 3-7, 2014, to add the high-level relationship
“Subject” to RDA. It will be applicable only to the Work
entity. Subject relationship designators will be
accommodated in a new appendix M in RDA Toolkit.
 Reasoning behind the decisions and intended impact
on the utility of RDA.
 Alignment with the FRBR and linked data (Dublin Core
Abstract Model) models.
 Changes to the RDA element set, relationship
designators, and RDA Registry.
 Treatment of embedded descriptions/citations.

Bottom line
“Subject” is not an entity
“Subject” is a relationship between a
Work and something else:
Work “(has) subject” something
Reciprocal relationship:
something “(is) subject (of)” Work
