What

Make it possible to call for a partial editing page.

• https://world.openfoodfacts.org/cgi/product.pl?type=edit&code=6191513501031&sections=ingredients,nutrition&mode=modal
• https://world.openfoodfacts.org/cgi/product.pl?type=edit&code=6191513501031&sections=ingredients,nutrition&mode=full

This would:

• allow 3rd party apps to lets their users edit products on a specific topic, or for a specific result
• Allow us to show restricted editing as a modal directly in the product page, for a specific result (compute the Nutri-Score, compute NOVA, compute the Eco-Score)

Part of

• ✏️ Editing (Tracker) #5525

Blocking

• Webview based product addition and edition smooth-app#509

If you use the api, you can already upload (only) the changed data.

A partial editing page would likely look out of place for most apps, and it might be difficult to use authentication effectively. I'd be inclined to encourage apps to use the existing API.
