Blueprints backend compatibility

[Raffaele Palmieri]

Dear all,
I would want to resume the discussion on the possibility of extending Marmotta
to use other compatible backends with Blueprints model, as the work done for
Titan.
I ask if anyone has done more tests for Titan backend, to understand the
limits of Marmotta, which should be the same that we will have if we
introduce another compatible backend with Blueprints.
Particularly I am seeing some projects that use Apache Accumulo as triple
store for Blueprints.
What do you think?
Raffaele.
