Re: Review of "SPARQL 1.1 Update"

Without really wanting to decide between "REMOVE" or separators ";" here yet (I am not decided on this, to be honest)...
what I'd find a slight bit strange is that in the first alternative DELETE needs a dedicated keyword in the shortcut 
version, whereas INSERT doesn't. One option to avoid and make it look more consistent could be to also have a dedicted 
keyword for the short form of INSERT, i.e.

long form:

 WHERE  {P3}

short forms:

 ADD {P}

just my two cents,

Basic data loading might be commonly one operation although surely much of the need for SPARQL Update Language is for those operations not done by the HTTP update style.  It will include things like ensuring graphs exist before other operations happen.
