Your welcome! Sorry, for the delayed response.

I'm saying that if you're going to use a natural key as the ID of a
document that you should namespace it. Like so:

{ "_id": "user:foo", "type": "user", "full_name": "Foo Baz Barington" }

That way, you can also have another kind of document, in a different
ID namespace, with the same natural key value. So, for instance, their
could be a book called Foo:

{ "_id": "book:foo", "type": "book", "title": "Foo" }

And their IDs wont collide.
