This module provides an Apache Marmotta backend using blueprints abstraction on Accumulograph. This is a suitable backend in high performance or big data scenarios. It does not support rule-based reasoning and versioning. NOTE: This backend uses the Apache licensed AccumuloGraph library together with other Apache licensed products. See from https://github.com/JHUAPL/AccumuloGraph/blob/master/LICENSE.
