For reference <http://www.pilod.nl/wiki/Virtuoso_questions>: What are the differences between the open source and the closed source version of Virtuoso? The main differences are the following which are closed source only: * Clustering & High Availability * Virtual Database * Replication * ACL control over large numbers of graphs High availability and replication are trouble for us. Just having an enterprise edition causes us to lower the score in general. Even though we don't need any of the CUDA stuff that Systap has for BlazeGraph it still lowers their score from the foundation's perspective. The trouble is that we anticipate conflict of interest issues if. We can always fork but that puts us in an undesirable position of being (probably) the only user of our fork. I've still reached out to its authors to see what they say if they open source their HA and replication code then we'd seriously consider them.
