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.


Attribute Best Practice: If the content of the <unstructured-kwd-group> element is a term from 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:
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”.
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/”.
