Thank you for asking this so clearly. Wish I knew :)
Many RDF implementations permit this in one form or another.
In SiRPAC a statement is a resource, so can be the subject of
another statement. The Jena API permits the same thing a
bit more explicitly:
graph.addProperty(new Statement(s,p,o),
property,
object);
We think we know how to implement this efficiently.
Not a great help with a clean model though.
