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. -- Regards, Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen President & CEO OpenLink Software Web: http://www.openlinksw.com
