We do plan to have a VoiD graph that exposes granular stats. 16-way shared-nothing cluster (virtuoso server instances), across two Sun Solaris x86_64 machines (Quad Cores), 16gigs of ram per machine. Current response time is set at 16 seconds, with a double up per retry. This is part 1, and much more data to be added from the LOD cloud. URI lookups are simply about a "Search" (i.e. full text pattern) and "Find" (i.e. Type or Property filtering en route to exposing values). The XML Web Service is now functional and you can test using the guide at: http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtuosoFacetsWebService Ideally, someone will use the XML Web Service to match and exceed Parallax without compromising any Linked Data essence (one of the motivations behind this service amongst many others). Finally, this entire system, once fully loaded, we be available for personal and service specific use via an Amazon EC2 AMI.
