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
