Cómo utilizarlo

 Esta página debe actualizarse con más información sobre cómo utilizar el servicio de consultas de Commons.

• Ejemplos de consultas en Commons
• Nota: Para saber cómo añadir datos, consulte Commons:Structured data/GLAM/Tools o Commons:Structured data/Get involved/Finding data.

El servicio de consultas de Commons utiliza Wikibase, Ayuda para consultas de Wikidata proporciona la documentación necesaria para utilizarlo excepto los identificadores M que se describen a continuación.

Notas de lanzamiento

• The service is a beta endpoint that is updated via weekly dumps. Some caveats include limited performance, expected downtimes, and no interface, naming, or backward compatibility stability guarantees.

The service is hosted on Wikimedia Cloud Services, with limited resources and limited monitoring. This means there may be random unplanned downtime. The data will be reloaded weekly on Mondays from dumps taken on Sunday. The dumps can be seen at https://dumps.wikimedia.org/other/wikibase/commonswiki/. The service will be down during data reload. With the current amount of SDoC data, downtime will last approximately 4 hours, but this may increase as SDoC data grows.

• Due to an issue with the dump format, the data currently only dates back to July 5th. We’re working on getting more up-to-date data and hope to have a solution soon. (T258507 and T258474)
• The MediaInfo concept URIs (e.g. http://commons.wikimedia.org/entity/M37200540) are currently HTTP; we may change these to HTTPS in the near future. Please comment on T258590 if you have concerns about this change.

• The service is restricted behind OAuth authentication, backed by Commons. You will need an account on Commons to access the service. It seems that OAuth is currently not working. See https://stackoverflow.com/questions/65303450/how-to-authenticate-to-wikimedia-commons-query-service-using-oauth-in-python#comment115828158_65424900. This is so that we can contact abusive bots and/or users and block them selectively as a last resort if needed.

• Please note that to correctly logout of the service, you need to use the logout link in WCQS - logging out of just Wikimedia Commons will not work for WCQS. This limitation will be lifted once we move to production.

• No documentation on the service is available yet except examples available at Commons:SPARQL query service/queries/examples following the format at Wikidata:SPARQL query service/queries/examples. Please add your own examples to this list.

• Please use the SPARQL template. Note that while there is currently a bug that doesn’t allow us to change the “Try it!” link endpoint, the examples will be displayed correctly on the WCQS GUI.

• WCQS is a work in progress and some bugs are to be expected, especially related to generalizing WDQS to fit SDoC data. For example, current bugs include:

• URI prefixes specific for SDoC data don’t yet work - you need to use full URIs if you want to query using them. Relations and Q items are defined by :* Autocomplete for SDoC items doesn’t work - without prefixes they’d be unusable anyway, but additional work will be required after we inject SDoC URI prefixes into WCQS GUI.
• If you find any additional bugs or issues, please report them via Phabricator with the tag wikidata-query-service.

Planes futuros

Tenemos previsto pasar el servicio a producción, pero aún no tenemos un calendario al respecto. Queremos hacer hincapié en que, aunque esperamos que un punto final SPARQL forme parte de una solución a medio y largo plazo, sólo será una parte de esa solución. Incluso una vez que el servicio esté listo para producción, seguirá teniendo limitaciones en términos de tiempos de espera, consultas costosas y federación. Algunos casos de uso tendrán que migrar, con el tiempo, a soluciones mejores, una vez que éstas existan.
