<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).

Remarks

Attribute Best Practice: If the content of the <compound-subject> 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.
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 <subj-group>, they need not be repeated on each <compound-subject>.
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/”.

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.)
