If I understand correctly RDF* aims to make it possible to describe,
and query facts about existing tuples. And can do that without
explicitly storing an intermediate representation of the target tuple.

It seems to me trivial to implement with a generic tuple store database
such as nstore. The exposed tuple store where n=m, then the 
implementation
will require m+1 tuple items where the extra tuple item is the hash
of the other items.

In practice, it would mean that every exposed tuple will be content 
addressable.

What I am missing?
