Allegrograph RDFStore, a database for the Semantic Web

Erik will share what he learned at PyCon about the Allegrograph database. This database stores and manipulates graph structures (as in comp sci graphs -- vertices and arcs). This can be used to support the Semantic Web.

From the website:

AllegroGraph is a modern, high-performance, persistent graph database. AllegroGraph uses efficient memory utilization in combination with disk-based storage, enabling it to scale to billions of quads while maintaining superior performance. AllegroGraph supports SPARQL, RDFS++, and Prolog reasoning from numerous client applications.
