How it works

This taxonomy contains the definition of the hierarchy of categories used in Open Food Facts.

The definition contains:

  • stopwords (words that can be ignored when matching category names)
  • word synonyms (words that can be exchanged when matching category names)
  • category synonyms (the synonyms are then matched also in other category names that contains those synonyms)

For more details, see Global taxonomies

Taxonomy definition

The taxonomy is now managed directly on GitHub: https://github.com/openfoodfacts/openfoodfacts-server/blob/master/taxonomies/categories.txt

Replace XX by your language. https://world-XX.openfoodfacts.org/categories?translate=1

Q&A

Q: I changed a string for a category via pull request (and it got accepted and merged). Will the new string appear on all the products once a new version is deployed and released?

A: It depends. The canonical categories (e.g. en:cakes) that are associated to each product won't be updated right away, only when products are processed again. The strings displayed for it (e.g. if you added a translation) will be shown right away.
