Thank you for your references. I did the following with a local installation (to a machine) of Virtuoso. I successfully loaded following items.

dbpedia_3.7.owl
instance_types_en.nt <http://downloads.dbpedia.org/3.7/en/instance_types_en.nt.bz2>

I know that I can query instances using my local server. One other requirement I have is to access the resource files I get from the query. How can I load the resource file using the data I load into the server? It is helpful if anyone can let me know what data files I may load into the server if it is possible to do so.

You could have loaded the rest of DBpedia too. Or just instantiate our Amazon EC2 AMI and you'll have a preloaded and pre-configured DBpedia instance. Once you are done you can shut it down etc..

So I am aware of its availability to all of us. The problem I am having is in getting rdf resource files from the servers when they are down. My access of server is to get resource files and if I want to have a local access, I need to replicate a full dump locally in a server. My access to dump depends on other resource files. For example, lets say I process http://dbpedia.org/page/Presidency_of_Barack_Obama resource and then in that file it states his birth place as a resource. Then I go on and process that rdf file for his birth place. I mentioned the alternative sparql endpoint to know if there is also an alternative dump set up for experiments like that endpoint since dbpedia main dataset is down for maintenance randomly. It would also be nice if we can get to know regular maintenance time slots so to avoid it.

I am looking for a solution of accessing dbpedia dataset without a random downtime. I do not mind the data is not the latest update. Any idea is greatly appreciated. Thank you.

Here are a variety of DBpedia data servers:

1. http://dbpedia.org/sparql
2. http://live.dbpedia.org/sparql
3. http://dbpedia-live.openlinksw.com/sparql
4. http://lod.openlinksw.com/sparql -- this is the biggest and fastest since it has a larger cluster setup behind it.

You can also instantiate your own DBpedia instances in the cloud for service specific needs. See: http://www.openlinksw.com/dataspace/dav/wiki/Main/VirtAWSDBpedia351C .

Hi,
I am in the process of testing a program that processes .rdf resource files over a period of time in DBpedia and compare it with Freebase resources. But I have been encountering many server downtimes and I also tried using the optional URL http://lod.openlinksw.com/sparql instead of the the http://lod.openlinksw.com/sparql. But still resource file access is anyway coming from DBpedia servers. Is there any alternative path that I can use? I observed downtimes very frequently and hence my program couldn't complete the test in all times. Thank you.

You really need to be a little clearer than that. For instance, what SPARQL are you executing? Why don't you download the RDF dumps for such effort? Have you read various posts in past about how to use DBpedia in a manner that reflects its availability to the rest of the world?
