Hi Josh, Betsy,


Have you looked at OpenLink Virtuoso?


There’s an open source version available, and the current release, v7.x, should scale quite well on a server with enough disk and RAM, easily storing several billion triples (MT).


It’s also available in a commercial, clustered, version. From personal experience, it’s fast, scales well, has inferencing support, and lots of SPARQL 1.1 features including property paths and aggregates.

Hi Betsy,


I have experimented with Jena, Sesame, MarkLogic and AllegroGraph in attempts to load all of our bibliographic data converted to RDF using marc2bibframe and some post processing. MarkLogic has decent integrated query tools. AllegroGraph had better built-in visualization tools. I had trouble loading all of our records into Jena or Sesame as the load would not complete due to the limits of memory management and the great number of strings in the converted data.

What are folks using for their test triplestore?  Apache Jena?  Something else?
