There is an interesting number of new systems capable of storing and managing very large graphs, e.g., for social networks or for the Web of Data. This project aims to compare the different systems, both from a feature perspective, and from an empirical perspective by developping and the deploying and measuring an application on top of different systems. Some of the systems envisioned for this task are: Neo4j http://www.neo4j.org/ , Titan http://thinkaurelius.github.io/titan/ , Giraffe http://giraph.apache.org/ and AsterData Graph.
