TL;DR: We are removing the PHP‑serialized output format from Special:EntityData on May 28. URLs like Q42.php and Accept: application/vnd.php.serialized requests will stop working. Please switch to JSON (example Q42.json) instead.
Hi everyone, We are making a significant change to the LinkedData interface on Wikidata. Starting May 28, the Special:EntityData page will no longer support the PHP‑serialized output format. This means - URLs like https://www.wikidata.org/wiki/Special:EntityData/Q42.php will return an error (HTTP 415 Unsupported Media Type). - Requests like https://www.wikidata.org/wiki/Special:EntityData/Q42 with the Accept: application/vnd.php.serialized header will return an error (HTTP 406 Not Acceptable). Why are we removing this format? - The PHP‑serialized format is not a stable or standardised data format. It can only be used by PHP applications and poses potential security risks. - Maintaining it adds unnecessary complexity and technical debt. - Usage is extremely low (approx. 2000 requests per day, mostly from bots), especially compared to JSON (millions) and RDF/Turtle (tens of millions). What should you use instead? Please use the JSON format, which is fully supported and stable. For example: https://www.wikidata.org/wiki/Special:EntityData/Q42.json For more details on all available formats and how to access them, see the Linked Data Interface section of the Data access page <https://www.wikidata.org/wiki/Wikidata:Data_access>. Timeline - May 20: The change is deployed to Test Wikidata <http://test.wikidata.org> and the Beta cluster <https://www.wikidata.beta.wmcloud.org/wiki/Wikidata:Main_Page>, where you can already test the new behaviour. - May 22: This announcement - May 28: The change will be deployed to Wikidata production. If you have any questions or concerns, please write directly on the Phabricator task (phab:T98035 <https://phabricator.wikimedia.org/T98035>). Cheers, -- Mohammed S.
