Knowledge panels are json data that describe content to be displayed to the user.

They are currently used on the [[Project Smoothie|new smoothie flutter application]] and, as an experimental feature, on the [[Product Opener]] web platform.

== Testing it ==
+
To test knowledge panels on the web application:
+
+
* if you are moderator, they are displayed so that you can report eventual bugs
+
* if you are a normal user, you can add <code>?panels=1</code> at the end of the url (eg: http://world.openfoodfacts.org/product/7804659650035/not-mayo-notco?panels=1
+
+
To see the knowledge panels jsons, use the [https://openfoodfacts.github.io/api-documentation/ api], that is, from a product page, you can add <code>/api/v2</code> before /product/, and append <code>fields=knowledge_panels</code> as query parameters.
