Quick Tweak to DBpedia Real-time Edition

All,

When I read the notice from Sebastian earlier today,  re. the new 
DBpedia & Wikipedia real-time variant, it dawned on me to use this new 
DBpedia instance to demonstrate a fundamental feature of DBpedia 
deployment. Basically,  what  I've referred to in prior commentary as a 
"subtle nuance" added to the Linked Data deployment mix.

Sequence:

1. Our DBpedia partners at University of Leipzig put out an initial bet 
cut of DBpedia with real-time links to Wikipedia
2. Their demo links are to the SPARQL endpoint which produces a basic 
Web results page without any live links (de-referencable URIs)
3. I ping Sebastian and indicate to him that by simply installing the 
DBpedia VAD package (Virtuoso's equivalent of an RPM) you will get the 
same Linked Data deployment used by the live DBpedia instance, our EC2 
AMIs, and the DBpedia on Virtuoso 6.0 instance that we are currently hot 
staging.

Post the above (about 3 mins or less for me to install the VAD from 
Burlington, MA into the instance in Leipzig, Germany), we now have:

1. http://db0.aksw.org:8890/resource/Virtuoso_Universal_Server
2. An owl:sameAs link to 
http://dbpedia.org/resource/Virtuoso_Universal_Server
3. Local URI dereferencing on the Leipzig Virtuoso instance  
(irrespective of the actual URIs in the Quad Store, think of this as 
outbound rewrite rules to complement inbound rewrite rules via SPARQL).

To conclude, this is a simple demonstration of how to address the 
problem of Linked Data Set propagation en route to Linked Data Web 
resilience i.e., a Linked Data Web where URIs may come and go, but the 
actual data (URI / Pointer referents) persist. The more replicas the 
more resilient the Linked Data Web becomes.
