Hi all, Plz ignore my previous email as i realized how to fix this ;-)
for the record i used req path = /cmn/data/(.*)$ dest path = /sparql?query=DESCRIBE%20%3Chttp%3A%2F%2Fpurl.org%2FNET%2Fclassicalmusicnav%23$U1%3E%20FROM%20%3Chttp%3A%2F%2Flocalhost%3A6666%2FDAV%2Fclassicalmusicnav-data%3E&format=%24accept i think the trick was specifying '$U1' in 'format' mode rather than 'sparql' mode... cheers, kurt On Thu, Jan 29, 2009 at 4:46 PM, Kurt J <kur...@gmail.com> wrote: > Hi Kingsley, > > Thanks for your quick reply - I understand this sparql-redirect > concept now in virtuoso. > > However, i'm having a problem still.
