<subj-group>

Subject Group

Container element for the subject matter designations describing a document’s content or a document component’s content. Subjects are used to organize documents into groupings (potentially hierarchical groupings) for display or print.

Remarks

Subjects (and groupings of subjects) are used, typically, to provide headings for groups of documents or document components in a printed, or online, generated Table of Contents.

In some journals, articles are grouped into categories which this Tag Set calls <subject>s, which may be grouped into <subj-group>s. Similarly, a book may use this mechanism to group <book-part>s. These subject categories are typically shown in the Table of Contents, at the top of the first print or display page, or on the web splash page for the work. Sometimes the grouping or category refers to the type of content, such as “Essay”, “Lesson”, “Award”, or “Unit”. Sometimes the grouping refers to subject areas, such as “Physical Sciences”, “Biological Sciences”, or “Social Sciences”. Sometimes the grouping refers to topics within the larger subject areas, such as “Applied Math”, “Biology”, or “Chemistry”. For example, a one-level grouping might be:

  <subj-group>
    <subject>Notation</subject>
  </subj-group>

or, as another example: 

  <subj-group>
    <subject>Magnetic Resonance</subject>
  </subj-group>

And a four-level grouping might be: 

  <subj-group subj-group-type="keywords"> 
     <subject>Biological Sciences</subject>
     <subj-group subj-group-type="keywords">
        <subject>Neuroscience</subject>
        <subj-group subj-group-type="keywords">
            <subject>Cellular and Molecular Biology</subject>  
          <subj-group subj-group-type="keywords">
               <subject>Blood–brain barrier</subject>
            </subj-group>
        </subj-group>
     </subj-group>
  </subj-group>

Books and book parts may be assigned to more than one grouping. For example, if a chapter is classified as “Biochemistry” under “Biological Sciences” and “Chemistry” under “Physical Sciences”, the <subj-group> container element may repeat. For example: 

  <subj-group>
    <subject>Chemical Disciplines</subject>
  
    <subj-group>
      <subject>Biological Sciences</subject>
  
      <subj-group>
        <subject>Biochemistry</subject>
      </subj-group>
    </subj-group>
  
    <subj-group>
      <subject>Physical Sciences</subject>
  
      <subj-group>
        <subject>Chemistry</subject>
      </subj-group>
    </subj-group>
  </subj-group>
