Platform requirements

See the release notes for more information on the different versions of this extension.


First install MediaWiki and Wikibase Repository.

The recommended way to install the GND extension 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 dnb/mediawiki-gnd:*
composer update dnb/mediawiki-gnd --no-dev -o

Enabling the extension

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

wfLoadExtension( 'GND' );

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

Usage: GND doku function

{{#gnd_doku:language=en|codings=PICA3, PICA+}}


  • language. Optional language code. Default de. Supports en and de.
  • codings. Optional. Coding columns to show. Default PICA3, PICA+, MARC21. Supports these 3 values.

Usage: GND import

GND import via ImportGndDump.php. Example:

php extensions/GND/maintenance/ImportGndDump.php --path extensions/GND/data/GND.json --limit 10

The import script expects a file with one JSON structure per line. Example of a valid file: https://github.com/ProfessionalWiki/GND/blob/master/tests/GND.json
