Thank you Gay for posting. I noticed an unfamiliar entity that is created by the Interpreter. Its InputForm is: Entity["Food", {EntityProperty["Food", "FoodType"] -> ContainsExactly[{ Entity["FoodType", "Elderberry"]}], EntityProperty["Food", "AddedFoodTypes"] -> ContainsExactly[{}]}] What kind of entity is this? I suspect it's a compound Entity given the "plus" sign and its own icon. The closest example I can find is in the first example in the "Scope" section in https://reference.wolfram.com/language/ref/Entity.html . However the syntax is about the first argument, not the second argument.

Thanks Dave for working with our post. The food entities have a unique design within the Wolfram Language, so I agree, it's a challenge to find comparable entities. The food entities can be more complex than other domains due to the many varieties of a single food that are possible. Our goal is to build entities for as many varieties of foods as feasible. Please send your input on Wolfram food data anytime. If I don't have the answer myself, I will be glad to research it.

Thanks for the reply, Gay. I will look into the entity syntax and experiment with food and other entity types. I named it a compound entity, but is there an official classification/name within Wolfram Research to address this type of Entity?
