<unstructured-kwd-group> Unstructured Keyword Group

Container element for one set of keywords used to describe a document, where the individual keywords are not tagged as separate <kwd>s but instead are all run together in one long text field.

Usage/Remarks

Attribute Best Practice

If the many terms in the <unstructured-kwd-group> are all from the same taxonomy, ontology, term-list, vocabulary, industry glossary, or other known source, then the vocabulary attributes should be used to record that source.
Vocabulary Identification Attributes
Two attributes are used in this Tag Set to identify a vocabulary. When these attributes are used on an <unstructured-kwd-group>, they apply to all keywords in the group.
vocab
Name of the controlled or uncontrolled vocabulary, taxonomy, ontology, index, database, or similar that is the source of the term. For example, the 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/”.
