No that is not exposed in the public API anywhere but can be fixed
internally and I have just done so, unfortunately I already made the
0.6.0 release this past weekend so the fix won't hit an official release
until 0.6.1 now

Hi Sherif / Rob,
The Virtuoso ADO.Net <http://ADO.Net> Provider DBcommand class has a
detault CommandTImeout
<http://msdn.microsoft.com/en-us/library/system.data.common.dbcommand_properties.aspx> property
value of 30 seconds, as detailed at:
http://docs.openlinksw.com/virtuoso/virtclientref.html#vcrvirtuosocommandclass
Which would be the timeout you are hitting, so does the dotNetRDF
library allow this property value to be set so it can be increased as
required ?
Best Regards
Hugh Williams
