This page gives an overview of the taxonomies and some guiding principles that are valid for all taxonomies. For each specific taxonomy there is a specific wikipage.

== Overview ==
  −
The list of taxonomies in use is:
  −
* ''Additives classes taxonomy''
  −
* ''Brands taxonomy'' for the producers of products and their corresponding brands. This taxonomy is not in use and still under construction (5-oct-2022);
  −
* ''Categories taxonomy'' used to put similar products together, so that they can be compared, averages calculated and analysed as a group. For instance an orange juice of a specific brand can be compared to all orange juices;
  −
* ''Countries taxonomy'' has a list of all countries, regions, areas, etc. in the world;
  −
* ''Ingredients taxonomy'' for ingredients found on product ingredients lists. Some specific ingredients have been put into separate taxonomies, as these need special handling due to legal requirements:
  −
** ''Additives taxonomy''
  −
** ''Allergens taxonomy''
  −
** ''Amino acids taxonomy''
  −
** ''[[Ingredients processing taxonomy]]''
  −
** ''Minerals taxonomy''
  −
** ''Nucleotides taxonomy''
  −
** ''Other nutritional substances taxonomy''
  −
** ''Vitamins taxonomy''
  −
* ''[[Labels taxonomy]]'' for every logo and claim by producer about product quality, supply chain, sourcing, diets, etc.;
  −
* ''[[Languages taxonomy]]'' with a list of world languages in multiple languages;
  −
* ''NOVA groups taxonomy''
  −
* ''Packaging/recycling taxonomies'' have been spread out over several specific taxonomies:
  −
** ''Materials taxonomy'' with a list of all possible materials that can be used;
  −
** ''Shapes taxonomy'' which describe all the packaging parts the packaging can consist of;
  −
** ''Recycling taxonomy'' with all ways packaging can be recycled;
  −
* ''States taxonomy'' which describe how complete the data of a product on OFF is;

== Building and deploying taxonomies ==
  −
 
  −
Changes to taxonomies on GitHub are not deployed instantly, the need to be built, deployed, and products need to be re-processed with the new taxonomy.
