This brings back the question of graph literals. Or should I say, 
literal graphs?

I have no problem with graph literal per se, and would be happy that a 
datatype for graph serialisation exist, but I would not like it to be 
mandated for talking about graphs.

I would rather use a different approach, which has been proposed already 
by Pat, IIRC:

"Graph IRIs" are just tags attached to an RDF graph and don't need to be 
interpreted as graphs in an RDF interpretation. For instance,

:cutekitty { :cutekitty a animal:Dog }

is fine. However, when you want to talk about the graph tagged with the 
Graph IRI :cutekitty, you provide a new URI (which must be interpreted 
as a graph) and connect it to the graph IRI as follows, for instance:

:cutekitty { :cutekitty a animal:Dog }
:graph1 :hasGraphIRI "http://example.org/cutekitty"^^xsd:anyURI ;
:me :believes :graph1 .

This leads to other problems if you publish this kind of things on the 
web but is probably working well inside a graph store.
