<compound-subject>

Compound Subject Name

Wrapper element to hold all the parts of a multi-part subject (for example, a subject term and the code representing that term).

Related Elements

The <compound-subject> may be used if a subject has multiple parts, but need not be used unless both parts need to be captured:
  • If a subject is only a word or phrase (Neuroscience, Physical Sciences), the simple <subject> element can be used to capture this information (<subject>Neuroscience</subject> or <subject>Physical Sciences</subject>).
  • If a subject contains both a term and a code (A11 Permeability) but only one of those objects needs to be captured, a <subject> element may still be used, to record either the code (<subject>A11</subject>) or the subject (<subject>Permeability</subject>). If such a compound subject is considered to be a single subject, the <subject> element may also be used: <subject>A11 Permeability</subject>.
  • If a subject contains both a term and a code, and it is useful to record both the code and the term separately, each can be captured as a <compound-subject-part>s inside a <compound-subject>. (See tagged examples below.)
