Content handlers

See also: Manual:ContentHandler , Help:ChangeContentModel

This page contains information about different content models and their implementations. It may be incomplete as any extension can add their own content model. Content model refers to the internal ID that represents that content type. The content format is the mime-type of ways the content can be represented (serialized) in.

Core content handlers

Content model	Content format(s)	Usage
css	text/css	For pages that contain CSS, like MediaWiki:Common.css
javascript	text/javascript	For pages that contain JavaScript, like MediaWiki:Common.js
json	application/json	A generic model that stores information in the JSON format. Many extension content handlers build on top of this.
text	text/plain	A generic model that displays plain text (no formatting). It is not intended to be used directly, but it can be.
wikitext	text/x-wiki	Wikitext! The default in most pages.
