I've been thinking about the expressive power of RDF* related to the
expressive power of RDF, at least the versions of RDF* that have been proposed
so far.

As far as I can tell anything that can be done in RDF* can be easily done in
RDF by using standard
RDF reification techniques, perhaps slightly modified (e.g., to account for
malformed literals), with extra properties linking to syntactic encodings to
achieve referential opacity.

But named graphs are more expressive than RDF* in a certain sense, as named
graphs allow multiple "embedded" triples to be collected together.
