You are missing an very important point. A SPARQL endpoint is a service, albeit exposed by a Web Page for Human Interaction. Also, the server behind DBpedia (Virtuoso) is deliberately configured to protect itself while also seeking to offer balanced access to DBpedia. What you won't be able to do with our instance is simply consume the service without regard for others etc..

If she does, I am all ears as to how she serves all conceivable users and user patterns across the Web 24/7 :-) Remember, you can download the DBpedia archives and upload to your own Quad or Triple store. One point of thanks, you seem to be one of the few people that actually include the DBpedia instance and SPARQL endpoint as being part of what constitutes the DBpedia Team or DBpedia Project :-) Kingsley > > baran. -- Regards, Kingsley Idehen President & CEO OpenLink Software Web: http://www.openlinksw.com Weblog: http://www.openlinksw.com/blog/~kidehen Twitter/Identi.ca: kidehen
