Extension:SiteMatrix

The SiteMatrix extension adds a special page with a matrix of all sites of the Wikimedia Foundation. First a table of all normal language wikis, with blue links for existing wikis and red links for non-existing wikis. Below a list of other special projects (like Meta, Commons, Wikimania, ...), mostly the sites like *.wikimedia.org. It also adds a NUMBEROFWIKIS parserfunction which shows the total number of wikis^[1] .

• Download and move the extracted SiteMatrix folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:

  cdextensions/
  gitclonehttps://gerrit.wikimedia.org/r/mediawiki/extensions/SiteMatrix
  

• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'SiteMatrix' );
  

• Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

There are some variables that you need to change:

• $wgSiteMatrixFile - The path to a list of language codes recognised by MediaWiki (example).
• $wgSiteMatrixPrivateSites - The path to a list of wiki databases that are private (optional)
• $wgSiteMatrixFishbowlSites - The path to a list of wiki databases that are public, but only logged in users can edit. (optional)
• $wgSiteMatrixClosedSites - The path of a list of wiki databases that "closed" (optional)

You would also need to customise $wgSiteMatrixSites to list the different wikis in your own wikifarm. To add a new site, follow the template in extension.json as a guide (but be sure to convert the syntax to PHP). As this has been removed for better compatibility, use the code below as a reference:

	"wiki": {
		"name": "Wikipedia",
		"host": "www.wikipedia.org",
		"prefix": "w"
	},
	"wiktionary": {
		"name": "Wiktionary",
		"host": "www.wiktionary.org",
		"prefix": "wikt"
	}

To ensure that the extension works correctly to your needs, there are a few dependencies to this extension:

• $wgLocalDatabases - To tell the extension all the wiki databases that exist in your wikifarm.
• $wgConf - To feed the extension with the correct links to the different wikis in your wikifarm.

This extension adds an API module that provides the same information as Special:SiteMatrix: a set of language groups plus special wikis.
