I guess from that comment that putting a graph does not overwite an existing 
one.  Is that the case?  I woudl liek to understand why these operations form a 
gropup and don't lead to a webdav-like set of requirements for graph manipulation.

Another way of structuring it would be one WSDL for query and service 
description, and one for GET-like(Retrieve)/PUT(Make)/DELETE(Drop) of graphs 
mapping closely to HTTP.  This would have the benefit of not making these 
distinguished from another (later) interface that manipulated contents of 
datasets.  Add to dataset, remove from dataset, get from dataset. etc etc.
