Value Objects in CQRS - where to use

Question

Answer 1

Value Objects are or at least should be immutable. Once instantiated with a value that value will never change throughout the lifetime of the object. Thus, passing VOs as data to DTOs (such as Events) should not be an issue since all you can do with them is get their value. At the most their value in a differing representation such as toString() as opposed to an original getValue() which might return an integer or whatever the value is.
