We provide the Wikidata QID, which is an unambiguous, stable and reliable identifier for a concept that will be useful to actually retrieve info from Wikipedia and Wikidata.

===== Example =====
 +
Camembert de Normandie >> https://world.openfoodfacts.org/category/camemberts-de-normandie >> Q1086855 >> https://www.wikidata.org/wiki/Q1086855<br>

As you see, you'll get a beautiful image, information about the Quality label… As Wikidata is a Wiki, the knowledge you'll be able to retrieve will increase over time.
