[TYPO3-mvc] ValueObject against Entity

[Federico Bernardin]

Hi Steffan,
You can say: 
when you change any object property and the object is completely different (it have to be destroyed and create again) this object is a value object.
If you change an object property but the object itself remain the same (in your repository) it's an entity.

A name or an address could be a value object but a customer or a person  (defined by many attributes) are entity. You can change address or telephone number of a person but it will not be changed (the id or identity of person remain unchanged), instead if you change the street of a value object (address) the address will be destroyed and recreate (this behavior depends by your domain analysis). 

regards
Federico
