Hi Piero,
The following document provides steps to load the latest DBpedia datasets
into Virtuoso using the Virtuoso Bulk loading scripts we now provide:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtBulkRDFLoaderExampleDbpedia
This is the method used for loading the current online dbpedia.org datasets,
the scripts in the blog post you reference are based on an older script we
provided previously and should still work in theory although we would recommend
the newer Virtuoso Bulk RDF load scripts.
I am also including the virtuoso-users email address on source forge in this
reply, as assistance can also be received from this mailing list with any
Virtuoso related issues, thus you probably should subscribe to the list at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VOSMailingLists
Let us know how you get on ...
Best Regards
Hugh Williams
