<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 content of the <unstructured-kwd-group> element is a term from a thesaurus, ontology, term-list, vocabulary, industry glossary
or other known source, the vocabulary attributes should be used to record that source.
This source can be a formal ontology or an informal field of study. Two attributes
are used in this Tag Set to identify such a controlled or 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 might be “http://dublincore.org/documents/2012/06/14/dces/”.
