Wikibase/FAQ/ja

What is the difference between Wikibase and Wikidata?
 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.

Is there a list of Wikibase instances?

Why doesn't the query service update?
If you find yourself re-importing RDF files to make items show up in the query service, even when your updater is running correctly, you're probably suffering from the MAX_DAYS issue.

Try running your updater with the following option, setting "DAYS" higher than 30: -DwikibaseMaxDaysBack=DAYS
