<compound-kwd> Compound Keyword
Wrapper element for multi-part keywords (for example, a code and its meaning).
Usage/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 <compound-kwd> contains terms from a single controlled vocabulary (ontology, taxonomy, term-list,
vocabulary, industry glossary, or other known source), the two vocabulary identification
attributes should be used to record that source. The vocabulary term identification
attributes may also be used to provide semantics for the keyword.
Vocabulary Identification Attributes
Two attributes are used in this Tag Set to identify a vocabulary. When these attributes
are used on a <compound-kwd>, they apply to the entire keyword.
vocab
|
Name of the controlled or uncontrolled vocabulary, taxonomy, ontology, index, database,
or similar that is the source of a 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/”.
|
Vocabulary 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 element display text content is “Digitized Version of Record” the attribute value might be “digitized-vor”
|
---|---|
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.
