Usage documentation

See the usage documentation.


This extension provides a REST API endpoint for exporting Wikibase items.

For more information, refer to the REST API documentation.


Platform requirements:

  • PHP 8.0 or later (tested up to 8.1)
  • MediaWiki 1.37 or later (tested up to 1.39)
  • Wikibase 1.37 or later (tested up to 1.39)

The recommended way to install Wikibase Export is using Composer with MediaWiki's built-in support for Composer.

On the commandline, go to your wikis root directory. Then run these two commands:

COMPOSER=composer.local.json composer require --no-update professional-wiki/wikibase-export:~1.0
composer update professional-wiki/wikibase-export --no-dev -o

Then enable the extension by adding the following to the bottom of your wikis LocalSettings.php file:

wfLoadExtension( 'WikibaseExport' );

You can verify the extension was enabled successfully by opening your wikis Special:Version page.

PHP Configuration

Configuration can be changed via LocalSettings.php.

Export configuration

In JSON format, following the JSON Schema at schema.json. Gets combined with rules defined on page MediaWiki:WikibaseExportConfig.

Variable: $wgWikibaseExport

Default: ""

Example: example.json

Caution: invalid JSON will be ignored. No error will be shown, the intended config will just not be applied.

Enable in-wiki configuration

If it should be possible to configure this extension via MediaWiki:WikibaseExportConfig.

Variable: $wgWikibaseExportEnableInWikiConfig

Default: true

Example: false

The page MediaWiki:WikibaseExportConfig will always be available. If this configuration is set to false, its contents will be ignored.

	"require": {
		"vimeo/psalm": "^4",
		"phpstan/phpstan": "^1.8.11"
	"extra": {
