Wikibase/API/ru

См. wikidata.org/w/api.php для полной, современной документации API MediaWiki, включающей модули 'wb' Wikibase. Документация генерируется из исходного кода.

Общее вступление
API Wikibase предоставляется набором расширений, реализующих модули API MediaWiki. Так что чтобы использовать его, вам следует быть несколько осведомлёнными на тему сетевого API MediaWiki: действия, query-запросы, и так далее, и, наоборот, ваши знания об общих параметрах, таких как,   и других, применимы к API Wikibase.

Wikibase и Викиданные
Wikibase предоставляет общий механизм хранения утверждений в виде структурированных данных. Любая вики на MediaWiki может запустить его.

(См. wikidata:Glossary для объяснения этих терминов.) На кластере Викимедиа, большинство вики не выполняют весь набор расширений Wikibase. Утверждения о пунктах находятся на сервере wikidata.org. Так как это включает утверждения о миллионах объектов из Википедий, по этому ресурсу неплохо бывает выполнить поиск!

(Склад Викимедиа обладает собственным Wikibase для свойств файлов на Складе.)

To generate API documentation for just one of these modules, append  to Special:ApiHelp; for example visit Special:ApiHelp/wbgetentities.

To generate API documentation for multiple modules on one page, pass module names separated by | as the  parameter to  ; for example, |query+wikibase|wbavailablebadges|wbcreateclaim|wbcreateredirect|wbeditentity|wbformatvalue|wbgetclaims|wbgetentities|wblinktitles|wbmergeitems|wbparsevalue|wbremoveclaims|wbremovequalifiers|wbremovereferences|wbsearchentities|wbsetaliases|wbsetclaim|wbsetclaimvalue|wbsetdescription|wbsetlabel|wbsetqualifier|wbsetreference|wbsetsitelink|wbsgetsuggestions this URL generates the documentation for all the modules listed above.

Клиенты Wikibase
Many Wikimedia wikis (but, not ) run the Extension:Wikibase Client extension. This lets API clients on them
 * query the  meta submodule to determine URLs for the full Wikibase repo see its API help
 * query the the  property submodule to get some Wikidata information about pages on the local wiki

POST и GET

 * Requests that change content should use a token.
 * Requests should use HTTP POST or GET requests according to api module. Modules that change content use POST. Use POST to avoid problem with non-behaving proxies.
 * Clients should be aware of and handle errors from the API.

Параметры модулей
There are some parameters that are nearly always available. Plural forms are used in those cases where a parameter can take several values.


 * id | ids : Identifies a specific entity or entities, most typical an item. Plural form is used in wbgetentities. Lists of ids should be separated by |.
 * site ∩ title | sites ∩ titles : Identifies a single item or multiple items. Plural form is used in wbgetentities. Only one of sites and titles can have multiple values at the same time.
 * language | languages : The language is used as a filter mechanism to filter labels and descriptions in get actions or to identify a specific language for set actions.
 * format : Should always be set to json (or jsonfm for debugging), or xml (or xmlfm for debugging), no other form is supported.
 * summary : Adds a user specified summary instead of the system generated one. If not provided the module will generate its own summary, and if this fails the item itself will provide a summary.
 * token : An encrypted string the requester must pass on shall the request be fulfilled.
 * baserevid : An id for the last known revision that must be passed on shall the server be able to detect edit collisions.

Normally the return value either has a success key with a boolean cast as an integer or an error key with an object of two, optionally three, keys code, info and "*". The last one is additional information. Information about the action is either passed on the top level or under item if its one single item or items if its several. If it is several items each is found under a key with its own item id. See and.


 * Note that empty objects are returned as json arrays and not as objects.
 * Note that empty parameters removes the actual entry from the item.

wbgetentities
Module to get the content of several entities, possibly with only parts of the entity included. Entities that are checked for existence, but not found, are reported (bugzilla:45509). During lookup both sites and titles can be a list, that is if the entities are items, but the shorter one is cycled to match the longer one. If one of the lists contain a single entry it will be used for all entries from the other list. If both lists are equally long the sitelinks will be well-formed pairs. getEntities( ( ids XOR ( sites, titles ) ), *props, *languages )
 * ids are numeric identifiers for existing entities, if the entities does not exist they will be marked as missing.
 * sites ∩ titles is pairs that identifies multiple existing entities (only items), if they do not exist they will be marked as missing.
 * props which list to report, possibly filtered by language if they are language specific. Possible values are labels, descriptions, sitelinks, claims, datatype, aliases. Note that sitelinks are not language specific.
 * sort
 * dir
 * languages are one or more languages to filter the list against. If it is missing all valid languages are reported.
 * languagefallback Apply language fallback for languages defined in the "languages" parameter
 * normalize Try to normalize the page title against the client site (This only works if exactly one site and one page have been given)
 * ungroupedlist Do not group snaks by property id

Token
See also Manual:Edit token.

Revision
The API uses revision ids for edit collision detection. If the revision id is known from an previous reply, page load or similar, then pass on the revision to the edit. Without the revision id it is not possible to detect edit collisions in a reliable way. If there is an edit collision the requester must acquire a newer revision id to be able to continue. This typically involves requesting wbgetentities for the item in question, and then storing (and using) the revision from the entry.

Errors
Possible errors for all modules can be found at, for example wbeditentity

"Expected" errors will will have a standardized form:

The servedby is given unconditionally for error messages, but could be missing for some less than fatal errors. In some cases error messages can be appended to a success and be called warning(s).
 * example :

All error messages from the Wikibase modules should be internationalized (i18n) and localized (l10n), but note that error messages from the base API system may not be localized. The user language for the logged in user (usually the same as in the web interface) will be the default for error messages. You can override this by supplying  in the URL query string

Do not test the info value for a particular error, instead use the code value as this will remain independent of localization.

An internationalized error message that isn't localized as it should will have additional angle brackets.

With correctly localized error message the angle brackets will go away and the info string will print out in clear text. Assuming the user is logged in and use English language it will print as something like the following. Switching to Norwegian in the Special:Preferences or by appending  it will change the text of the info string to a localized variant, while the code string remains constant. A lot of error messages are not properly localized.
 * example :

Достижения
Может быть удалён, так как все обычные вызовы вернут какого-либо рода данные, если не возникло ошибочное состояние.

Если достигнут «успех», у него будет следующая форма, когда

Интерпретация значения «успеха» может зависеть от непосредственных параметров вызова, но обычно это булево значение, приведённое к целочисленному типу. Его смысл — то, что все предыдущие проверки имели результат true. Если число равно нулю, какие-либо дополнительные значения могут быть неправильными.

В структуре после успешного вызова могут быть дополнительные значения.
