Oh, OK! That explains why you haven't seen some of the comments, I'm sure!

OK! Then it needs to be simplified a lot, I think. I mean, most developers 
would probably get a long way by just being told that "the graph URI identifies 
a bunch of triples. If you GET, PUT and DELETE those triples RESTfully, it 
does what you think it does. If you POST, then you add those that aren't 
already there".

Right, it has been in my previous comments. I think all the definitions would 
only serve to confuse people, if it can't be defined in already familiar terms, 
we're doing something wrong. Sections that I find overly opaque include such 
things as I have pointed out earlier, such as that if a DELETE of a non-
existant graph is attempted, it should say so explicitly, but also note that I 
dispute the usefulness of this approach.

I posted a few comments in October and November about parts of the spec that I 
found too ambigious when I wrote an implementation, which makes it feel 
underspecified.

Cheers,

Kjetil
