Hi Chris,
Have you been able to get the provided test program for testing the Redland
connectivity and storage to Virtuoso as detailed at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtRDFDriverRedland
As that I would assume to be the starting point and once working then seek to
connect from Python and other such languages etc.
Best Regards
Hugh Williams
