Leveraging links to wikidata
How to leverage links to Wikidata (and Wikipedia) {#link_to_wikipedia_and_wikidata}#
- You may have spotted things like https://www.wikidata.org/wiki/Q40050 in API outputs, especially those related to Taxonomies
- 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...\
- 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.

As Wikidata is a Wiki, the knowledge you\'ll be able to retrieve will increase over time.
