    RDFox A Modern Materialisation-Based RDF System
    Abstract:
    RDFox is a new materialisation-based RDF system currently being developed at Oxford University. The system is currently RAM-based, and its algorithms have been designed to take full advantage of modern multi-core/processor systems. In my talk I will present an overview of some of the techniques we developed in the context of the RDFox project. In particular, I will discuss our algorithm that parallelises computation with very little overhead, I will present an overview of our lock-free indexes for RDF data, and I will discuss a novel incremental update algorithm. I will also briefly talk about some issues that we are currently working on, such as improving query planning and distributing data in a cluster of servers.
