This is the Open Food Facts food category, which represents a food category on Open Food Facts. A food category is as narrow as "Apple Pie" or as broad as "Wines", and list all instance of products. We support translations and synonyms, so we'll be able to better help enriching Wikidata and keep Open Food Fact's taxonomies more aligned with Wikidata.

use for taxons?[edit]
should we use this for plants and animals? Q158994#P1821 is a grass. i suppose the food part is only the grain of the grass (i'm not an expert). I'd argure this should be a separate (subclass of food product (Q951964)) entity--Shisma (talk) 14:15, 16 February 2020 (UTC)
Ping @Teolemon:
Canonical URL and IDs use language prefix[edit]
The ID appears to be tied to a language if one looks at the canonical URL for these IDs - the format should be lang : ID such as en:nutmeg while the page title are just the language. This language prefix format is supported by the https://wiki.openfoodfacts.org/Global_taxonomies#Wikidata section. Will improve the constraint. Wolfgang8741 (talk) 19:18, 16 September 2022 (UTC)
