vocab-identifier Vocabulary/Taxonomy Identifier

Unique identifier of the controlled vocabulary, taxonomy, ontology, database, thesaurus, index, etc. that is the source of the content in the element, for example, the controlled vocabulary for a group of terms such as a keywords or subjects. The content is typically (but is not limited to) a URI or DOI.

Usage/Remarks

Four attributes are used in this Tag Set to identify terms from a controlled or an uncontrolled vocabulary:
vocab
Name of the controlled or uncontrolled vocabulary, taxonomy, ontology, index, database, or similar that is the source of the term. For example, for a subject term, a value might be the IPC Codes (“ipc”) or MESH headings (“mesh”). For an uncontrolled term, the value might be an area of study such as “medical-devices” or merely the word “uncontrolled”.
vocab-identifier
Unique identifier of the vocabulary, such as (but not limited to) a URI or DOI. For example, for Dublin Core (DCC), the identifier may be http://dublincore.org/documents/2012/06/14/dces/. For the NISO CRediT, Contributor Roles Taxonomy, the identifier may be http://credit.niso.org/.
vocab-term
The content of the element is the display version of the vocabulary or taxonomic term. The @vocab-term attribute holds the canonical version of the same term, as it appears in the vocabulary. For example, if the attribute value is “digitized-vor”, the element might contain the display text “Digitized Version of Record”.
vocab-term-identifier
Unique identifier of the term within a specific vocabulary, such as (but not limited to) an item number, a URI, DOI, etc.
