He described this as 'something happened that the domain experts care about'. They provide a way of representing the state of an entity and lead to clearer, more expressive model. This sounded very similar to an approach Nick has described to me whereby we would have a new object that represented a specific state of an object. 'Every change to an object is a new object' was the take away quote from this part of the talk for me - I think an explicit approach to modeling is far superior to an implicit one.
