When all is said an done, this is basically about the power of data 
access by reference combined with logic based schemas. As I state 
repeatedly, this is the "holy grail" for those who've grappled with 
these matters long before the emergence of today's ubiquitous InterWeb.  
It is also why the real narrative has to be about how contemporary 
infrastructure (InterWeb, URIs, and EAV) have emerged to solve some 
really old headaches.

OpenLink built and sold secure ODBC drivers to corporations (still does) 
on the back of a trust graph based on data containers (files) hosting 
EAV content using the old INI notation for graphs. It's how we were able 
sell drivers that handled scenarios like departmental partitioning such 
that payroll, pensions, 401K data etc. was protected via enterprise 
specific rules i.e., we gave our customers the infrastructure to 
implement their own rules etc..

Today, WebID enables us to deliver the same functionality via URIs, EAV 
based Linked Data graphs (RDF and other formats), SPARQL, and user 
definable trust models (ontologies).

Privacy (where vulnerability is calibrated by the vulnerable) is the 
biggest problem on this planet today, due to InterWeb ubiquity. We now 
have critical infrastructure in place for addressing this problem head-on.
