Does named graph play a role here? For example, data (triples) generated 
from a project (experiment) may only be accessed by the one(s) who did 
the experiment (as well as the lab PI). Also, there may be multiple 
projects/experiments going on within a lab. The PI of the lab should be 
able to access data generated from all projects/experiments within the 
lab. Access control may be given at the experiment/project level and the 
lab level ...
