<compound-kwd>
Compound Keyword
Wrapper element for multi-part keywords (for example, a code and its meaning).
Remarks
Some keywords are a simple word or phrase; such keywords should generally be tagged using the <kwd> element. The <compound-kwd> element is used when keywords are composed of multiple parts, such as:
- a code and its meaning, or
- an abbreviation and its expansion.
Attribute Best Practice: If the content of the <compound-kwd> element is a term from a controlled vocabulary (ontology, taxonomy, term-list, vocabulary, industry glossary, or other known source), the vocabulary attributes should be used to identify that source. The source named can be a formal ontology or an informal field of study.
Term Identification Attributes: Two attributes are used in this Tag Set to identify an individual term from a vocabulary (controlled or an uncontrolled):
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. |
Vocabulary Identification Attributes: Two attributes are used in this Tag Set to identify a vocabulary. If these attributes have already been used on <kwd-group>, they need not be repeated on each <compound-kwd>.
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/”. |
