The @deferred query marker was introduced in Semantic MediaWiki 3.0.0Released on an unknown date unknown versions of MediaWiki.

Rationale

The @deferred marker will postpone (defer) the result generation until after a page has been processed and its static HTML content was published by making use of the MediaWiki API (where the parser cache is not in effect) and thus improve the loading time of pages with inline queries (via the #ask or #show parser function) and at the same provide up-to-date results.

Only selected result formats support the @deferred query marker.1 This marker in turn allows for the usage of the @control query marker.

Example

Syntax

{{#show:
 {{FULLPAGENAME}} 
 |link=none
 |@deferred
}}

or

{{#ask:
 [[Category:Foo]]
 |link=none
 |@deferred
}}
