Open Food Facts (Product data)

Open Prices relies on Open Food Facts product data.

Why

Having product data directly in Open Prices allows for a better contributor experience and easy filtering/aggregation/stats.

What is used

Backend

• Product table - all 4 product flavors (food, beauty, pet food, products, as well as obsolete food products) are stored - we keep only a subset of fields (code, name, brands, categories...)
• Taxonomies - we manipulate taxonomies for specific use cases (e.g. challenges)
• Contributing back - we allow creating products back to OFF (with the open-prices username)
• all thanks to openfoodfacts-python

see open_prices/common/openfoodfacts.py

Frontend

• Taxonomies (categories, labels, origins, languages) are used in some forms - thanks to openfoodfacts-python - see https://github.com/openfoodfacts/open-prices-frontend/tree/main/data
• Barcode scanner - thanks to openfoodfacts-webcomponents

Data sync

With Redis, Open Prices gets instant product changes.

There is also a daily batch sync to be sure we don't miss anything.
