Vad är skillnaden mellan Wikibase och 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.

Finns det en lista över Wikibase-instanser?

Although there’s no single canonical list, on our Showcase page we highlight several notable instances. For more comprehensive information you can check out the voluntary Wikibase registry and this list of federated query endpoints.

Programvara och funktionalitet

Hur installerar jag Wikibase i mitt eget system?

There are currently three options for installing Wikibase.

Var hittar jag mer information om frågesystemet?

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

Hur fungerar federationer?

Check out our federation page.

Hur hämtar man data till Wikibase?

Check out our import tools page.

Kommer Wikibase med en webb-API (som api.php) för fjärranslutning?

Wikibase extends the standard MediaWiki action API with modules such as action=wbsetsitelink and query modules such as action=query&prop=pageterms. You access these modules via api.php like the rest of the API and you can use d:Special:ApiSandbox to explore the API. Some Wikimedia wikis run only the Wikibase client, while runs the full software.

Var hittar jag källkoden?

Check out our developer resources. An updated programmer's guide and coding conventions are in the works!

How do permissions work in Wikibase?

See Wikibase/Permissions for a detailed explanation and a helpful table.

Who maintains Wikibase?

The Wikibase extension is primarily maintained by the engineering teams of Wikimedia Deutschland.

Wikibase/Suite and Wikibase/Docker provide a software suite including not only the Wikibase extension to MediaWiki but also accompanying software like Elasticsearch, QuickStatements and the Wikidata Query Service. Other than Wikibase and the WDQS front end, Wikimedia Deutschland doesn't maintain any of these components.

Why hasn't a particular bugfix been applied to Wikibase?

Wikimedia Deutschland is dedicated to providing critical security fixes to all the Wikibase Suite components as they become available. But due to limited resources, Wikimedia Deutschland can't commit to adding any given new functionality or applying fixes to non-critical bugs in the software we don't maintain. Requests of that kind are best directed to the maintainers of each software component.

How should I report security issues in Wikibase?

Follow the instructions on the Reporting security bugs page.

Tekniska frågor

We cover many technical topics in our maintenance guide, the GitHub repository for our Docker images and our manual install documentation. Below you'll find help on some specific issues reported by users of Wikibase.

Varför uppdateras inte frågetjänsten?


Wikibase's WDQS updater will refuse to ingest updates older than 30 days.

But when you start Wikibase's WDQS updater for the first time, the timestamp of the most recent edit is set to 30 days. So if you start a new instance of Wikibase with the query service and its updater, and you then stop the updater without making an edit, you guarantee that the updater will never again ingest an update.

Avoiding the problem

To avoid this problem, simply make a trivial edit after starting your query service & updater for the first time; also avoid gaps in updates longer than 30 days.

Fixing the problem

But if you find yourself in this situation already, you can fix it by stopping the updater and restarting it with the following flag: --start YYYYMMDDHHMMSS (that's four-digit year, two-digit month and day, and hours, minutes and seconds on a 24-hour clock)

The complete invocation should look something like this:

docker exec cluster_name_wdqs_1 bash -c '/wdqs/ -h http://${WDQS_HOST}:${WDQS_PORT} -- --wikibaseUrl ${WIKIBASE_SCHEME}://${WIKIBASE_HOST} --conceptUri ${WIKIBASE_SCHEME}://${WIKIBASE_HOST} --entityNamespaces ${WDQS_ENTITY_NAMESPACES} --init --start 20210315120000'

A less manual solution is underway; see this Phabricator ticket for more.

How can I get more questions and answers added to this FAQ?

If you have a question and answer that you think other Wikibase users might benefit from seeing here, please add it -- just as you would edit any wiki page. (You may see further edits from one or more technical writers who will be keeping the page tidy and its categories and style consistent, but don't let that deter you!)
