Yesterday Facebook announced a new feature called Graph Search.  This Graph
includes 1 billion people,  240 billion photos, and over 1 trillion
connections.

Graph search is privacy aware:  every piece of content has its own
specified audience. Most content is not public; you can only search for
content that has been shared with you.

RDF data stores are also currently capable of  loading a trillion triples
("connections"), and we have hardware such as the Cray  purpose built for
graph analytics.

There is also work done on a natural language query interface for RDF using
Cyc as the foundation ontology.

While not a "success story" of RDF per se,  Graph Search (if anyone knows
what its actual technology is)  may be at least an endorsement of the
RDF-like approach to managing, repurposing, and securing data.

Is there any reason to believe that an RDF-based system could not also:
1. Enable similar storage and query as Graph Search?
2. Provide similar data-atomic granular control of privacy of (personal or
healthcare) data similar to that of Graph Search?
