Hi all,
in one of the last messages Hugh suggested to use the dumping/loading
scripts as explained here:
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFDatasetDump
to move data between Virtuoso instances. When the database is "big"
though this can be less practical than just m

Question 1: When you start a new/empty Virtuoso 7 database the initialisation
