The default graph bit isn't, as that has no URI. But it's still out of  
scope for this WG to change that.

Yes, that is quite a complex issue. I remember discussing something  
around this area with Dave - regarding SPARQL stores as a cache. I  
don't think that was discussed in the F2F meetings though, so I not
