Thanks for the responses below plus the one Martynas sent about Dydra. If anyone has another idea, please send it along. Betsy From: Bibliographic Framework Transition Initiative Forum [mailto:[log in to unmask]] On Behalf Of John, Phil (CSS) Sent: Monday, April 20, 2015 4:51 AM To: [log in to unmask] Subject: Re: [BIBFRAME] test triplestore 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. Phil.

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. - Josh Joshua Greben Software Developer Stanford University Libraries 650-714-1937 [log in to unmask]<mailto:[log in to unmask]> On Apr 15, 2015, at 11:34 AM, Simpson, Betsy <[log in to unmask]<mailto:[log in to unmask]>> wrote: What are folks using for their test triplestore?
