How would you design objects whose purpose it is to get “metadata” from models? Example in post.

Let’s say I got a model called “Chef”. This object has methods such as what kinds of dishes this chef is able to cook. Like Chef->getAvailableDishes() or something. Now I have some code in another part of the application where I would want to get some “metadata” about this chef, which is a combination of methods and calculations made with the help of the Chef object.

For example ChefMetadataHelper::canCookDish($dish); or ChefMetadataHelper::hasEnoughTimeOverToCookDishesOnDate($dishes, $date).

Like… some form of other objects that interact and usually return boolean values for question asked around in the code base. What would you call these objects? What’s the best approach?
