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

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.
