have an attribute called display name and content form it's it's a pretty simple one uh we can be a bit more uh descriptive so again we could have a seller but we could also signify that the seller is actually a user so we would have a relationship to some existing user and in this case our consumers can get even more data about it but looking at this example we can also uh think about the third example is that relation to the seller is a user so we can just have a resource user and we can have his username and phone uh directly attached
