Well, the problem is entirely within BigData(R) and its console explorer
application.
The wealth of public FOAF profiles do use blank nodes, and there is no
possibility to make people rewrite them.
On the other hand, the BigData(R) console explorer application must do
something sensible to show blank nodes to the user.
It's up to the BigData team to do something for that, and then other
applications will do the same.

That being said, a possibility I see is to distinguish between 2 kinds of
bnodes:
- 1. the ones that come from original data like public FOAF profiles
- 2.  the ones that were created by the database, as result of inference or
SPARQL node creation
