This help page describes the upgrade procedure from Semantic MediaWiki 3.2.x to Semantic MediaWiki 4.0.x with native Composer support.

Note that this help page assumes that you use MediaWiki 1.35.0 to 1.37.x. See also the help page on compatibility.

Step 1 - Backup database and wiki[edit]

Backup your wiki database and wiki installation.

Step 2 - Update setup file[edit]

Change to the base directory of your wiki1 in your server's shell and modify the "composer.local.json" file to look like this2:

{
	"require": {
                  "mediawiki/semantic-media-wiki": "~4.0.0"
        }
}

Step 3 - Update software[edit]

Run the composer command34 from the base directory of your wiki1 in your server's shell to upgrade the source code of Semantic MediaWiki and dependencies:

php composer.phar update --no-dev

Step 4 - Invoke Semantic MediaWiki[edit]

Add the following lines to the end of your "LocalSettings.php" file:

wfLoadExtension( 'SemanticMediaWiki' );
enableSemantics( 'example.org' );

Note that "example.org" should be replaced by your wiki's domain.

BREAKING: Until Semantic MediaWiki 3.2.x the calls wfLoadExtension( … ); or wfLoadExtensions( … ); must not be added to invoke Semantic MediaWiki. Now you must to do this.

Step 5 - Update database[edit]

Run maintenance script "update.php" (MediaWiki.org) from the base directory of your wiki1 in your server's shell to apply the schema changes to your wiki's database:

php maintenance/update.php

Or alternatively use maintenance script "setupStore.php"Allows to set up the data backend/store:

php extensions/SemanticMediaWiki/maintenance/setupStore.php

Done![edit]

Semantic MediaWiki and the database use should now be upgraded properly. The wiki may now be used again.
