Here is an article that argues for support of other data semantics in the Web
of Data (RDF world) beyond description logics. In here, you will find examples
of other forms of reasoning.
http://arxiv.org/abs/0905.3378
Unlike the triple/quad-store world, graph databases provide a very generic data
model with limited constraints on meaning. Unfortunately (in my opinion), graph
databases like OrientDB and DEX employ typing at the graph database level.
Neo4j provides it at the Spring Data Graph level -- a level above. This is good
in that Neo4j is not pushing a world view to low into the stack. The world of
RDF, on the other hand, and its strong bent towards OWL (description logic)
makes it such that the entire technology stack is mixed up with this logic.
And, while this logic is very cool, its not the only way to do things -- the
only way to view the world.
---- however, at some point, there is always an assumption, and the
foundational assumption of graph databases is "all reasoning is best with a
linked list data structure."
See ya,
Marko.
