can anyone voluteer to help your (1) programmer fix this problem? if not then why not accept donations to hire a few people to help out? I would donate money, and i'm sure that others would too. if so where can i send it to?
The page at http://dmoz.org/rdf/tags.html will show you the status of the RDF dump as well as some of the reasons for the failure. Others are more complex and not detailed in the report.
Remember that the RDF dump is produced while people are still editing the database, so this is a non-trivial programing exercise. There are several reasons for the failure, but it is being looked at. As the dump takes a week, it means that it takes a week to find out if the latest correction did actually fix it or not.
