Is there a handy way to reify the statements and work that way?

In ARC's internal structure (for example) statements do have internal=20
IDs. However, these IDs aren't URIs, they're the relational IDs of the=20
backend MySQL store, so they can't be used to describe the statement.
This of course isn't a weakness of ARC, it's just the way RDF works.
