<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
For more information on the handling of compound keywords, see the tagging practices section Complex/Compound/Nested Keywords.

Related Elements

This Tag Set contains several differently-structured types of keywords:
  • <kwd> is used with simple keywords: words or phrases.
  • <compound-kwd> is used with multi-part keywords, such as a keyword that is a code-and-term pair.
  • <nested-kwd> is used with hierarchical keywords structures, such as taxonomies, to record a portion of a taxonomic hierarchy. Both simple and compound keywords can be nested hierarchically.
  • <unstructured-kwd-group> is used to hold one long keyword, in which the multiple constituent keywords are not tagged individually.
