Template:Excerpt

From mediawiki.org
Template documentation

This template is used for reusing parts of pages in other pages. This practice has several advantages:

  • Reduces maintenance by avoiding duplicate content that must be updated multiple times
  • Improves content quality by encouraging editors to merge related content, rather than having multiple versions in various stages of development
  • Fosters collaboration by channeling contributors into one place, rather than working in parallel

This template extends the capabilities of the built-in normal transclusion.

Usage

    • templates=-Infobox — Transclude all templates except 'Infobox'
    • templates=-Infobox, Navbox, Chart — Transclude all templates except 'Infobox', 'Navbox' and 'Chart'
  • this — Change the initial text of the hatnote. For example, if the transcluded content is a gallery, you can set this=This gallery is so that the hatnote reads "This gallery is an excerpt from..."
  • displaytitle — Change the text of the link in the hatnote. For example to add italics, subscripts, etc.
  • hat=no — Hide the hatnote "This section is an excerpt from..."
  • more=yes — Show a "Read more..." link at the end

  • quote=yes — Wrap the excerpt with ‎<blockquote> tags.
  • inline=yes — Remove the hatnote and ‎<div> tags around the excerpt, to use it inside other text.
  • references=no — Remove all references.
  • subsections=yes — Include subsections of the transcluded section. Notice that if the transclusion is done from a section level 3, and the transcluded subsections are level 3 too, then the transcluded subsections will show with the same hierarchy as the transcluding section, which is probably not desirable, so use with caution.

Replacing a section with an excerpt

How to replace a section with an excerpt.

A section is often a summary of a more precise page dealing with a subtopic. Sometimes it's convenient to replace the content of such a section with an excerpt of the page about the subtopic, after merging the original content of the section (if any) into the page about the subtopic. This improves both the page about the subtopic and the section, reduces maintenance, drives contributors to collaborate, etc.

An efficient way to proceed is:

  1. Open the section for editing in one tab, and the page about the subtopic in another.
  2. Copy the text of the section and append it to the lead of the page about the subtopic.
  3. Consolidate and adjust the combined lead using common sense.
  4. Save the changes in the child article with an edit summary like: Copied content from [[Page]]; see that article's history for attribution.
  5. Back in the section, delete all content and replace it with an excerpt of the page about the subtopic.
  6. Save the changes in the section with an edit summary like: Move content to [[page about the subtopic]] and leave an excerpt.

Excerpt trees

Visual representation of an imaginary excerpt tree.

When a very general article uses excerpts from more specific articles, which in turn use excerpts from even more specific articles, then a tree structure emerges, called an "Excerpt tree".

Below you can navigate the main excerpt trees on this wiki. It's useful for editors interested in expanding or improving them.
