• Contributors

What

• Implement ingredients origins input

Tasklist

• Note: This will require a server upgrade with a structure very similar to the one @stephanegigandet is creating for packaging input

Foundations

• Add support for autocomplete on the origins taxonomy
• Use the partial taxonomy API to get origins (Add support for the Origins taxonomy openfoodfacts-dart#596)
  • https://world.openfoodfacts.org/api/v2/taxonomy?tagtype=origins&include_root_entries=1&include_children=0&lc=fr&cc=fr
  • Implement full/guided ingredients origins input (tracker) #517

User interface

• Add a screen for structured ingredient origin input
  • List detected ingredients with their origins as editable items
    • 
  • Add a toggle to validate the fact that all origins have been inputted
    • Request server-side support for origin of ingredients completion status
• Add a screen to edit the origin of a given ingredient
  • 
• Add an origin selector based on the Origins taxonomy
• Add an option to take a photographic proof of origins (to be uploaded as an additional image, until we have a specific support for it)

Nice to have - Low priority

• (Very low priority) Add support to ask for the fishing zone if the category is fish
  • This would require either hardcoding or the ability to work on sub-parts of a taxonomy (eg: all labels with the fishing label category)
• (Very low priority) Add support to ask for the fishing technique is the category is Fish
  • This would require either hardcoding or the ability to work on sub-parts of a taxonomy (eg: all labels with the fishing label category)
