At the current time here is what we have:

1. DBpedia
2. NeuroCommons
3. Bio2Rdf
4. Musicbrainz
5. PingTheSemanticWeb (the root for many Semantic Web search engines 
e.g. Falcons and Sindice)
6. Uniprot
7. Many more to come as part of our effort to put the entire LOD cloud 
into a Virtuoso 6.0 Cluster Edition.


1. http://lod.openlinksw.com/fct/facet.vsp - Faceted Browser (runs 
inside Virtuoso)
2. http://lod.openlinksw.com/sparql - normal SPARQL endpoint

Cache is pretty cold, so a few query hits are required for general warm 
up. Also, we haven't set the 2-3 second response time ceiling, so any 
queries presented right now are executed without the "anytime query" 
feature. We've decided not to impose the server side ceiling until we've 
update the UI. Once done,  users (UI or Web Service API)  can then 
configure their response time factors within a floor and ceiling range 
set on the server. Thus, the moment you see the options in the UI you 
can safely assume the response time floor and ceiling settings  are in 
place on the server.

For those interested in URI lookups, as per my last mail about this 
matter, you can search on: Telemann, then use Types to filter out the 
types of entities associated with the pattern and then use properties to 
get you to your desired entity/object/resource which will naturally 
expose a URI / Entity ID.

You can also search on "Napoleon" and ultimately see a map (note. the 
navigation section drop-down) that will plot locations of conflicts 
associated with the entity "Napoleon".
