Hi,

That article describes Neo4j's RDF module which is being deprecated for
GraphSail (aka Blueprints Sail).
https://github.com/tinkerpop/blueprints/wiki/Sail-Ouplementation
With GraphSail there is a 1-to-1 mapping between property graph and RDF graph.
This way, you can move smoothly between the different representational layers.
The lack of a 1-to-1 mapping has been an problem with RDF layers atop graph
databases -- there usually isn't a clean underlying graph representation as to
satisfy RDF peculiarities (named graphs, spog querying, literals, etc.). As
such, graph databases have to do some data model magic in the backend. The
problem with this is that it leaves the developer stuck in RDF land. Blueprints
Sail (GraphSail) rectifies this situation by ensuring that there is a 1-to-1
map and thus, all the various ecosystems of technology can be happily used.
