Whenever possible, Open Food Facts entities are linked to Wikidata, and in turn to Wikipedia. What this means is that you get access to a trove of additional encyclopedic knowledge about food. You can for instance get: Wikipedia articles about Camembert, the translation of salt in many languages, the molecular structure of a cosmetic ingredient…
==== Link to Wikipedia and Wikidata ====
You have to use the Wikipedia and Wikidata APIs (here and here) to get the information you want
Whenever possible, Open Food Facts entities are linked to Wikidata, and in turn to Wikipedia. What this means is that you get access to a trove of additional encyclopedic knowledge about food. You can for instance get: Wikipedia articles about Camembert, the translation of salt in many languages, the molecular structure of a cosmetic ingredient…<br>
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.
==== Retrieving info from Wikipedia and Wikidata ====
You can use the Wikipedia and Wikidata APIs to get the information you want<br>
* https://www.wikidata.org/wiki/Wikidata:Data_access
* https://en.wikipedia.org/w/api.php
==== Examples of things you can do ====
* Provide more context and more information about a specific Product, a Category of products, a Quality label, a Geography, a Brand, a Packaging material, an ingredient…
* Perform checks or computations by mixing Wikidata information and Open Food Facts information (and possibly other APIs)
