Frequently asked questions

What is the difference between Wikibase and Wikidata?

Wikibase is a suite of knowledge-base software for managing linked open data, originally written for and still used by the Wikidata project.

Wikidata is the largest instance of Wikibase, a free knowledge base that anyone can edit. Its data is used by Wikipedia, by its sister projects and by anyone else who wants to make use of a large amount of open general-purpose data.

How can I set up my own Wikibase instance?

Use our quick and easy setup with Docker. Or take a look at our Docker repository, or the containers themselves over on Docker hub.

Where can I find the source code?

Here's our github mirror.

If you're interested in contributing code, check out our programmer's guide, after which you can request a developer account.

Where can I report issues or problems with Wikibase?

You're welcome to raise an issue on our Phabricator instance, where you can log in with your Wikimedia unified account or a Wikitech developer account.

Before you do, you may want to review the bug report guidelines.

Is there a list of Wikibase instances?

There's not a single canonical list—on our Showcase page we highlight several notable instances, but for more comprehensive information you can check out the voluntary Wikibase registry and the list of federated query endpoints.

Where can I find more info about the query service?

Here's Wikidata's query service manual and some SPARQL examples.
