<subtitle>

Document Subtitle

Subordinate part of a title for a document or document component.

Remarks

In Metadata: In the article metadata, the article subtitle and title are identified separately and tagged with two different elements, the <article-title> and <subtitle> elements.
In Citations: Within a bibliographic reference citation, the subtitle of a document cannot be preserved separately as this Tag Set identifies no cited-subtitle elements. How the subtitle should be tagged depends on how the citation is tagged.
For references tagged with either the <element-citation> or the <nlm-citation> elements, since these two models do not permit untagged text there are two choices:
  • The subtitle may be included with the title inside the <article-title> element for journal articles or inside the <source> element for book titles, proceedings titles, and other titles, or
  • The subtitle may be tagged as <named-content> with a @content-type of “subtitle”.
For references tagged with the <mixed-citation> element, there are three choices:
  • The subtitle may be included with the title inside the <article-title> element for journal articles or inside the <source> element for book titles, proceedings titles, and other titles,
  • The subtitle may be left as untagged data characters within the text of the reference, or
  • The subtitle may be tagged as <named-content> with a @content-type of “subtitle”.
Best Practice In Citations: Although this Tag Set cannot enforce either practice, retrieval performance will be enhanced if the subtitle for all cited material is consistently placed within the <article-title> element for journal articles and within the <source> element for book titles, proceedings titles, and other documents. When marked as either a <named-content> or left as untagged text, the subtitle is easy to lose to searching. It is also not always easy to identify, particularly with historical or foreign material, which part of a multipart title is the main title and which the subtitle.

Related Elements

There are several elements concerned with the title of an article, all contained within the container element <title-group> in the article metadata:
  • The <article-title> is the full title of the article in the original language of the document.
  • The <subtitle> is a subordinate or auxiliary title that adds information to the full title or modifies the full title.
  • The <alt-title> is another version of an article title, usually created so that the title can be processed in a distinct way, for example, a short version of the title for use in a Table of Contents, an ASCII title, or a version of the title to be used in the right-running-head.
  • The <trans-title-group> is also a container element, inside the <title-group>, that holds together a translated title (<trans-title>) and its translated subtitle (<trans-subtitle>). The translated title is a version of the title translated into a language other than the original language of publication, and the matching subtitle is a version of the subtitle translated into a language other than the original language.
