Hi Mirko, I am asking what is the command line tool you are using to run the commands giving problems ? The reference to unixODBC in your error message indicates to me you are not using the Virtuoso isql tool as this does not use unixODBC. The Virtuoso isql tool will be in the "bin" direc

Hi Hugh, I ran the query via the ssh shell, is that what you mean by SQL client? I also tried it via the SPARQL webinterface (www.myhost.org: 8890/sparql). The examples from the doc don't work either. I can't even load data with ttlp. Here is what I get: Query string: ttlp( [ example from

Hi Mirko, What is this SQL client you are using that references unixODBC as I presume it is not the Virtuoso isql client ? Have you tried using the Virtuoso isql client to create the rule set as detailed in the documentation at: http://docs.openlinksw.com/virtuoso/rdfsparqlrule.h
