Dear All,
Is it possible to create a spatial index in Virtuoso for spatial RDF
data. If yes, then what is the command for the same.
I have a deadline on 19th April. Therefore, I'll greatly appreciate an
early response.

I am using Virtuoso
engine(http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/).
For entering a query into Virtuoso engine, the following needs to be
done:
The virtuoso engine starts and gives the command prompt:
[myMachine]$ ./isql
Connected to OpenLink Virtuoso
Driver: 07.20.3213 O
I have entered my data into Virtuoso in named graph form. By mistake the
named graphs inserted in Virtuoso have type xsd:double for some literals.
Now I want to update all literals loaded in Virtuoso which have type
xsd:double to type xsd:float. Is it possible to do the same? If yes,
how.

Sorry the subject is wrong. I want to find out the range of numerical
values supported by Virtuoso?

I need to execute the following query:
select ?a?c?d (?c + ?d as ?score) where{graph ?g{?a ?b} graph
?g1{?a ?c} graph ?g2{?a ?d}}
Here ?c, ?d, ?score are numbers of any of the following type:
xsd:decimal, xsd:double, xsd:integer, etc. Can someone please tell me
the numerical range of these dat
Can Virtuoso (version 6 and above) evaluate SPARQL 1.1 query features
like ORDER BY, LIMIT, etc. If yes, then can you please explain how
ORDER BY and LIMIT are internally processed by Virtuoso query
processing engine.

I want to run about 1000 queries on Virtuoso about 100 times in order to
note their query execution times. Is it possible to do so in an automated
fashion using Virtuoso?

Hi,
In one of the papers "Sparqling Kleene - Fast Property Paths in RDF-3X", it
is mentioned that Virtuoso instance takes 20GB of main memory. Is it
possible to find the amount of main memory consumed by Virtuoso?

I think the questions asked by other users help me a lot in understanding
virtuoso. Is it possible to view all the questions asked by various users
at one place (as I subscribed to the mailing list only recently)?

I am trying to view the output of status() command, since the output is
long therefore I am unable to view it all on the command line. Is there a
way to redirect the output to a text file?

Rapidly troubleshoot problems
Dear Developers,
I installed 07.00.3207 OpenLink Virtuoso. After this I tried to load
dbpedia to virtuoso. When loading 40+ GB files using DB.DBA.TTLP_MTWhen
loading large files (2GB) using
DB.DBA.TTLP_MT(file_to_string_output('filename'),'','graphname',512);
virtuoso hangs (CPU usage 0%). With

I mean is the time returned by explain() the query execution time excluding
the compilation time?

Actually I do not have admin privileges on the server which I am using, so
wont be able to upgrade to version 7. Therefore it will be really great if
there is a method by which I may do profiling with virtuoso version 6.

After this virtuoso returns the query execution time. So does the returned

Can you please shed more light at: what is the method in Virtuoso by which
I may associate a graph group ? It will be great if you could point me to
some links or illustrate by an example.

is there a way to delete all the default graphs and quads in virtuoso
before loading new quads into it.
Thanks a lot for helping
