Hi,
Thank you all for the help.
I was thinking, wouldn't it nice if one could delete data by simply
passing some parameters to a function.
Please see example below ...
Insert data:
ld_dir ('/usr/local/virtuoso-opensource/share/virtuoso/tmp',
'someData.n3', 'http://someGraph');
Delete data:
ld_dir_delete ('/usr/local/virtuoso-opensource/share/virtuoso/tmp',
'partOfSomeData.n3', 'http://someGraph');
Regards,
Eliza
