Wat is de Wikibase API?
Wikibase biedt een algemeen mechanisme om statements op te slaan als gestructureerde data. The statements about items live on the server at wikidata.org. Zie Wikidata:Glossary voor meer informatie over Wikibase en andere concepten.



The Wikibase API allows querying, adding, removing and editing information on Wikidata or any other Wikibase instance.

Het wordt verstrekt door een set extensies die MediaWiki API-modules implementeren. So, to use the Wikibase API, you should have a basic familiarity with the MediaWiki Action API: actions, queries, etc., as well as with generic parameters such as  and.

How to use the Wikibase api
Send requests to the API through HTTP, the same as with the MediaWiki Action API. See API:Tutorial#How to use it for information about how to use the MediaWiki Action API.

Request Format
The endpoint for the API is https://wikidata.org/w/api.php.

In the query string, add the action parameter, which tells the API which action to perform. For example,  tells the API to get the data for Wikibase entities. For meta and property submodules, use and   respectively.

Some parameters are nearly always available. Plural forms are used in those cases in which a parameter can take several values. The parameters are:

GET request
Explanation of each part of the URL:


 * is the main endpoint.
 * tells the API to get the data for Wikibase entities.
 * means get the data from English Wikipedia.
 * indicates the title of the page to get data from.
 * indicates properties to get from the entities, in this case the property is the descriptions of the entities.
 * means filter the results down to the English language.
 * indicates JSON output, which is the recommended output format.

Response
Het antwoord op een verzoek zal doorgaans bevatten:


 * A  key with a boolean cast as an integer if the request is successful. If the integer is zero, any additional values might be wrong.
 * An  key with an object of two, optionally three keys, ,   and  , if the request is unsuccessful.
 * Information about the action. The information is either passed on the top level or under item if it is one single item or items if it is several. If it is several items, each is found under a key with its own item id.

Empty objects are returned as JSON arrays and not as objects, while empty parameters remove the actual entry from the item.

Meta submodules

 * wikibase: Gets information about the Wikibase client and the associated Wikibase repository.
 * wbcontentlanguages: Returns information about the content languages Wikibase accepts in different contexts.

Property submodules

 * wbcreateredirect: Creates Entity redirects.
 * wbeditentity: Creates a single new Wikibase entity and modifies it with serialised information.
 * wbformatvalue: Formats DataValues.
 * wbgetclaims: Gets Wikibase claims.
 * wblinktitles: Associates two pages on two different wikis with a Wikibase item.
 * wbmergeitems: Merges multiple items.
 * wbparsevalue: Parses values using a ValueParser.
 * wbremoveclaims: Removes Wikibase claims.
 * wbremovequalifiers: Removes a qualifier from a claim.

 * wbsgetsuggestions: Gets suggestions of additional properties to add to a Wikibase entity.
 * wbcheckconstraints: Performs constraint checks on any entity you want and returns the result.
 * wbcheckconstraintparameters: Checks the constraint parameters of constraint statements.

Mogelijke errors
Om eventuele fouten te vinden, gebruik de module. The error format corresponds to that of the MediaWiki Action API. See API:Errors and warnings#Legacy format.

All error messages from the Wikibase modules should be internationalized (i18n) and localized (l10n). The user language for the logged-in user will be the default for error messages, but you can override this by adding  to the URL query string.

Additional notes
De Kalendermodelle wat met Wikibase gebruikt kan worden,is de Gregoriaanse kalender(Q1985727) en de Juliaanse Kalender($2). De API gebruik hersienings-id's voor de opsporing van botsingen.Als daar een wysigningbotsing is,moet de versoeker een nieuwer hersienings -id verkrijgt om te kunnen voortgaan.Het behelst gewoonlijk dat u   voor het betrokken item aanvra,en da de  hersiening vanaf het abonnement slaat op(en gebruik). Elkie Mediawiki Installatie kan Wikibase laat loopt.In de Wikimedia groep bevatten de meeste wiki's niet het volledige stel Wikibase uitbreidingen. Wikimeda Commons heeft een eigen Wikibase voor de eigenschappen van de bestanden op commons
 * Many Wikimedia wikis run the Wikibase Client extension. This lets API clients on them to query the  meta submodule to determine URLs for the full Wikibase repo, and the   property submodule to get some Wikidata information about pages on the local wiki.
 * Do not test the  value for a particular error, instead use the   value as this will remain independent of localization.
