Dear all, I am facing a relatively simple problem, but it seems like there is no mechanism to really address this issue: I have a large RDF database (>400 million triples, dozens of named graphs) in a Virtuoso 5 instance that I want to transfer to a Virtuoso 6 instance. What is the best way of doing that? The main problem is re-creating the named graphs. Virtuoso still has no mechanism to dump RDF data including graph provenance (correct?), and using the backup/restore functionality will not work when different versions of Virtuoso are involved (correct?).
It would be great to have a simple feature in Virtuoso that allows the user to dump RDF data including the graph information (e.g., in TriX format, or in 'N-Quadruples' format). Cheers, Matthias
