<compound-subject-part>

Compound Subject Part Name

Individual component of a multi-part subject (for example, subject term, code for the term).

Remarks

Subjects are used, typically, in searching and discovery or to provide headings for groups of articles in a printed or online generated Table of Contents. This element can name one of the components of a subject when that subject is a multi-part subject rather than a simple subject.
Best Practice: The @content-type attribute should be used to indicate the type of the various subject parts, for example, “text”, “code”, “sponsor”, “taxonomy number”, etc.

Related Elements

A <compound-subject-part> 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.)
