Subject Grouping Name

Name of one subject or topic used to describe an article. Such topics and groupings of topics are typically used to provide headings for groups of articles in a printed, or online, generated Table of Contents.

Remarks

For some journals, articles are grouped into categories which this Tag Set calls <subject>s, which may be grouped in to <subj-group>. These subject categories are typically shown in the print or display of an article. Sometimes the grouping or category refers to the type of article, such as “Essay”, “Commentary”, or “Article”. 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 three-level grouping might be:

<subj-group>
<subject>Articles</subject>

<subj-group>
<subject>Biological Sciences</subject>

<subj-group>
<subject>Entomology</subject>
</subj-group>
</subj-group>
</subj-group>

And a one-level grouping might be:

<subj-group>
<subject>Retraction</subject>
</subj-group>

or, as another example:

<subj-group>
<subject>Essay</subject>
</subj-group>

Articles may also be assigned to more than one grouping. For example, if an article is classified as “Biochemistry” under “Biological Sciences” and “Chemistry” under “Physical Sciences”, the <subj-group> container element may repeat. For example:

<subj-group>
<subject>Articles</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>
