Our Wikibase Extensions

Enhance your Wikibase with one of our highly integrated Wikibase extensions. Or commission us to do Wikibase development of the highest quality for your project.

The Automated Values extension lets you define rules to automatically create labels and aliases based on statement values. It was released in 2022 and created for the Luxembourg Ministry of Culture.

Wikibase Local Media allows you to work with images uploaded in your own Wikibase wiki. This was one of the most requested features by the community, till we created the extension in 2020. Wikibase Local Media is included in the official Docker releases curated by Wikimedia since Wikibase version 1.35.

Wikibase EDTF adds support for the 2019 EDTF standard to Wikibase. EDTF stands for Extended Date Time Format. We created this extension for the Luxembourg Ministry of Culture in 2021. It is included in the official Wikibase Docker image releases since Wikibase version 1.36.

Semantic Wikibase allows you to use your Wikibase data in Semantic MediaWiki. This gives you access to embedded visualizations, autocompletion in forms and more. We created Semantic Wikibase in 2020 and it is still somewhat experimental.

GND

Our GND extension is a domain specific Wikibase utility for the German National Library. It allows importing of GND PICA+ exports as well as querying and visualising structured documentation. We developed this Wikibase extension in 2021
