A subject is a term, keyword, classification code or phrase representing the primary topic or topics covered by a registry object. This information answers the questions: What subject terms describe the topic of this object? What is it about?
Subjects support searching and discovery in Research Data Australia.
Use Subject to associate activities with the field of activity, collections with the subject matter of items in the collection, and parties with a field of activity or occupation. Services can be assigned subjects and may also be associated with a topic through the collections which they support.
Subject Type records the name of an authoritative list or controlled vocabulary from which a subject term or phrase is taken or that governs its form.
A Subject Type is optional. If used, preferably specify a type using the Subject Type vocabulary below. Values for Subject Type may also be taken from the Library of Congress Source Codes for Subjects list.
ANZSRC codes are the preferred vocabulary for describing research domain entities and activities in the RDA Registry. The RDA Registry accepts values from both the 2020 release of ANZSRC and the superceded 2008 release.

Many subject terms come from controlled vocabularies or classification schemes which can be represented by unique codes or persistent URIs, which resolve to further explanation about the term or are “linked data” URIs; the TermIdentifier attribute allows these codes and URIs to be included. Research Data Australia is not currently using term identifiers, but they will be integral to future integration with the Research Vocabularies Australia controlled vocabulary service and Research Data Australia. Contributors are encouraged to provide term identifiers in anticipation of these developments.
The language in which the subject metadata is recorded may be included in the Lang attribute, but is not displayed or searchable in Research Data Australia. The RDA Registry accepts language codes consistent with IETF's BCP (Best Current Practice) 47: Tags for Identifying Languages (incorporating RFC 5646). Language codes may be selected from:
