Hi Eliza,
yes, that command deletes all the triples in the graph.
If you need to delete specific triples then you need to write a SPARQL
query.
You have two options:
1) Virtuoso implements SPARUL commands, see the documentation here:
http://docs.openlinksw.com/virtuoso/sparqlextensions.html#rdfsparul
2) You can also write standard SPARQL 1.1 DELETE queries like the ones
specified here
http://www.w3.org/TR/sparql11-update/#deleteInsert
best regards,
Lorena

Hi Lorena,
Thanks for the help.
The command you gave me deletes the entire graph. Is it correct?
Is there a way to delete just a portion of a graph that's specified in
a file?
Regards,
Eliza

Subject: Re: [Virtuoso-users] Deleting data from a graph
Hi Eliza
what I usually do is run the following SPARQL query in isql
SPARQL DEFINE sql:log-enable 3 CLEAR GRAPH <http://someGraph>;

Hi,
The following command loads a dataset to a graph:
ld_dir ('/usr/local/virtuoso-opensource/share/virtuoso/tmp',
'someData.n3', 'http://someGraph');
Is there a way to run an isql command to delete data from a graph?
Thanks,
Eliza
