View source for Knowledge panels

[[Category:Knowledge panels]]
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 on the [[Product Opener]] web platform.

Introduction: https://openfoodfacts.github.io/openfoodfacts-server/introduction/knowledge-panels/

Reference documentation: https://openfoodfacts.github.io/openfoodfacts-server/reference/api/#get-/api/v2/product/-barcode--fields-knowledge_panels

== Testing it ==
Knowledge panels are already deployed for every body !

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.

Eg: http://world.openfoodfacts.org/api/v2/product/7804659650035/not-mayo-notco?fields=knowledge_panels

'''FIXME:''' eventually move this part of this to https://openfoodfacts.github.io/openfoodfacts-server/introduction/api/

== The flexibility of a static page ? ==
* Use the same system as for static pages, with much more Q&A ?
* Add a mode to get the raw file without the Product Opener UI
* https://fr.openfoodfacts.org/nutriscore?nochrome=1
* https://fr.openfoodfacts.org/knol/label/organic?nochrome=1
* Would allow to display them on the web as well

== What should we do with the native Wikidata integration on Android ? ==
* Move the logic on the server, with caching, and let iOS and other apps benefit as well ?
* Blend the Wikidata info with our own
* System to add Wikidata IDs to categories, labels… (working as a special language, using the existing translation system ?)

== When should network calls be made ? ==
* The apps would attempt to call all labels at setup, and then refresh on some heuristic
* On demand call when clicking on an attribute or a label
