Hi Hugh,
Thanks for the link to the tips on loading RDF data. Anyway, it's
slightly reassuring to know that it's not taking a *ridiculously* long
time, at least in comparison to others' experiences (though the computer
is Intel Dual Core, with fast
Hi Alex,
The duration of the load can be long depending on the speed (cpu/
memory etc) and configuration of your server ( machine and virtuoso)
and number of datasets being loaded. General tips on tuning for
loading RDF data is available at:

Hi Dhaval,
You indicate the error occurs when running complex queries can you
provide an example of such queries in comparison with those that work.
If you could provide a sample program we could compile in house to
recreate the issue that would be even better. It might also be useful
to
I tried getting RDF results of a query through JAVA. I used the
jdbc example occurring in the Virtuoso documentation, but Literals with
xml:lang specification return as java String.
The drivers I tested:
* recent virtjdbc3.jar (ftp'd just now)
OpenLink Virtuoso(TM) Driver for JDBC(TM) Version 3.
Hi Hugh,
I have tried with the latest jdbc driver from the link you had sent. Still
the same error:

Hi Hugh,
As suggested in your previous email, I altered the load script to
increase the tolerances, and this seems to have allowed the datasets to
install fine. However, having let the install script run for over four
days now, it has been in the post
Hi Dhaval,
What is the version number of the Virtuoso JDBC Driver being used
( java virtuoso.jdbc3.Driver) ? Can you please re-try with the latest
cut available from:

Hi Ruben,
Ok, so it a BIF (built in function) in the server binary for speed,
which means the change needs to be recompiled into the binary which is
possible for open source users as you have done ...

Hi Mirko,
You can remove a graph rule from the rule set using the option
"remove" parameter of the rdfs_rule_set function as detailed at:
http://docs.openlinksw.com/virtuoso/rdfsparqlrule.html#rdfsparqlrulemake
So, something like:
rdfs_rule_set (name, graph, remove (1))

Hi,
I have a program to run the construct queries from API ( snippet below). For
complex queries, while executed it complains with the following:
Convert results are FAILED.:virtuoso.jdbc3.VirtuosoException: Bad column
number : 2 not in 1
The code you suggested, the rdfdesc_http_url function of
description.sql. When we change to something like this:
create procedure rdfdesc_http_url (in url varchar)
{
..
-- host := http_request_header(http_request_header(), 'Host', null,
null);
host := 'data.fundacionctic.org';
Hi Ruben,
What changes are you making that are not taking effect ? You should be
able to drop and create changes made to any procedures changed, or
worse case rebuild the server should these functions be build into the
Virtuoso binary ...
