Hi all 

I've been looking over the latest drafts and the Uniform HTTP
Protocol has a feature missing which I'd rather like to see in it which is
the ability to delete individual triples from a Graph. 

While the POST
command will allow for the appending of triples to a Graph there is no
means to remove triples from a Graph short of doing a DELETE on the Graph
and then a PUT to load the new version. I realise that the removal of
triples is somewhat trickier from an implementation point of view because
of blank nodes but this feature would surely be useful to end users? 

I
see there's been some discussion about whether the new PATCH verb should be
incorporated into the protocol and I would suggest that this might be a
possible use for the verb (though I know some members of the WG are
advocating using it in place of POST for additive updates)
