It's obviously good to have means for recovery but I'd really like to have 
means to protect this important data from unauthorized deletion/modification.
I'm currently trying to make one application work with Virtuoso instead of  
some custom solution. Unfortunately this application was written in 
assumption that it is the only user of the RDF data so there are some places 
(which I want to find and eliminate) that can touch data in this system 
graph.
Are there any means to set per-graph read/write permissions and raise an 
exception when an application-user tries to violate them?
