Moral rights have been around for a while but with sparse and inconsistent support. My understanding is that these rights are distinct from copyright, although the two are obviously closely related.
In Australia apparently moral rights only came
into effect in 2000. In a note about
Ownership of Copyright they say: "Creators of copyright works have moral rights in relation to what they create, whether or not they are the copyright owner."
According to the Wikipedia article on
moral rights "Copyright law in the United States emphasizes protection of financial reward over protection of creative attribution."
All of which goes some way to explaining why moral rights are rarely discussed when we get into these regular discussions about copyright. And generally that's okay because they are distinct and separable, and don't change the fact that copyright is a property that can be bought and sold.
