== Categorisation ==
 +
The categorisation intends to bring some order into the thousands of labels that are listed on OFF. No overreaching hierarchy exists at the moment. Probably it is impossible to create one. But we attempt anyway and see if we can introduce some order.
 +
 +
=== Examples ===
 +
Some ordering attempts have been made already
 +
* Animal welfare to show how animals are treated during the production process:
 +
** [https://world.openfoodfacts.org/label/nl:beter-leven nl:Beter Leven] for the life of pigs, etc.
 +
** [https://world.openfoodfacts.org/label/Free%20range%20eggs Free range eggs] for eggs produced in free range
 +
* Prices to indicate the the product has a certain quality
 +
** [https://world.openfoodfacts.org/label/en:World%20Beer%20Awards World Beer Awards] a yearly award to the best beers;
 +
* Ingredients
 +
** [https://world.openfoodfacts.org/label/en:No%20gluten No gluten] for product that contain no gluten
