abstract

The abstract element occurs between the topic title and the topic body, as the initial content of a topic. It can contain paragraph-level content as well as one or more shortdesc elements which can be used for providing link previews or summaries. The <abstract> element cannot be overridden by maps, but its contained <shortdesc> elements can be, for the purpose of creating link summaries or previews.

Use the <abstract> element when the initial paragraph of a topic is unsuitable for use as a link preview or for summaries, for example because it contains lists or tables, or because only a portion of the paragraph is suitable. Note that when the initial paragraph is suitable as a summary, that content should be placed in a <shortdesc> element rather than in an <abstract> element. The <abstract> element allows for a wider range of content in your initial paragraph, such as lists and tables, and allows you to identify portions of the <abstract> content as useful for previews or summaries by embedding the <shortdesc> element within <abstract>.

When the contained <shortdesc> occurs within phrase-level content, it is treated as phrase-level content and should not create a separate paragraph on output of the topic. When the contained <shortdesc> occurs as a peer to paragraph-level content, it is treated as block-level content and should create a separate paragraph on output of the topic. When multiple <shortdesc> elements are included in an <abstract>, they are concatenated in output of link previews or summaries (separated by spaces).

Example: abstract with phrase-level short description

<abstract>The abstract is being used to provide more complex content. 
	<shortdesc>The shortdesc must be directly contained by the abstract.</shortdesc>
The abstract can put text around the shortdesc.
</abstract>
Topic output
The abstract is being used to provide more complex content. The shortdesc must be directly contained by the abstract. The abstract can put text around the shortdesc.
Preview/summary output
The shortdesc must be directly contained by the abstract.

Example: abstract with block-level short description

<abstract><p>The abstract is being used to provide more complex content.</p> 
	<shortdesc>The shortdesc must be directly contained by the abstract.</shortdesc>
<p>The abstract can put text around the shortdesc.</p>
</abstract>
Topic output

The abstract is being used to provide more complex content.

The shortdesc must be directly contained by the abstract.

The abstract can put text around the shortdesc.

Preview/summary output
The shortdesc must be directly contained by the abstract.

Example: abstract with multiple short descriptions

<abstract>The abstract is being used to provide more complex content. 
	<shortdesc>The shortdesc must be directly contained by the abstract.</shortdesc>
	<p>The abstract can put text around the shortdesc.</p>
	<shortdesc>There can be more than one shortdesc.</shortdesc>
</abstract>
Topic output

There can be more than one shortdesc.

Preview/summary output
