Yes, the \ escapes the $. The $s would look for variable s and try to insert
it into
the string. The """ prevent you from having to escape quotes and multiple
lines etc.

I print out the string and it looks valid.

select $s $p $o from <rmi://localhost/server1#content> where $s $p $o;

I managed to execute an insert from the tutorial and get it back with a
"select". This leads
me to believe that there is something wrong with the content.rdf
