Shortcut: WD:DR

A collection of database reports relevant to the upkeep of Wikidata. Inspired by en:WP:DBR. Requests for new reports can be made on the talk page. The source code is posted on Github. Patches and contributions are all welcome.

Note: Special:PrefixIndex/Wikidata:Database reports/Constraint violations lists all pages that have the prefix "Wikidata:Database reports", but the items below are sometimes not using that prefix and thus not shown in that listing.

Reports can be based on several sources:

Toolserver queries
age depends on the replication lag of the Toolserver. This can be limited to minutes, but sometimes grows to days or weeks.
For information about replag, see .
Full database dumps
age depends on the availability of a new full dump. This can be less than a week ago, but sometimes grows to weeks or months.
For the last available ones, see . See also:
Incremental database dumps
these are made available daily and include most information since the last full dump.
For the last available ones, see . See also: status of today's incremental dump
Wikidata API
This provides live data. See

Depending on the source used to generate the reports, these can be more or less up to date.

The planned query feature will allow to query and display reports on Wikidata directly.
