Hi Hugh,
Indeed, I was attempting to upload the .nt files using WebDAV. Perhaps this
is a restriction of WebDav? I'm pretty sure it's not the client (curl), as
I've already looked into that.
Thanks for your suggestion regarding the TTLP functions. I tried out the one
suggested with that link, but I'm having trouble with the simple matter of
specifying the path of the local file. All the .nt files for the DBpedia
dataset are currently contained in a 'DBpedia' dir under the Virtuoso root
installation dir.
The following is my console log (from isql):
SQL> DB.DBA.TTLP_MT_LOCAL_FILE ('DBpedia/articlecategories_en.nt', '',
'http://l
ocalhost/');
*** Error 42000: [OpenLink][Virtuoso ODBC Driver][Virtuoso Server]SR598:
TURTLE
parser has failed to open file 'DBpedia\articlecategories_en.nt' for reading
at line 37 of Top-Level:
DB.DBA.TTLP_MT_LOCAL_FILE ('DBpedia/articlecategories_en.nt', '',
'http://localh
ost/')
Am I doing something obviously wrong here? Clearly, I'm trying to specify a
relative path, but an absolute path gives me no better results:
SQL> DB.DBA.TTLP_MT_LOCAL_FILE
('C:\virtuoso-opensource\DBpedia\articlecategorie
s_en.n3', '', 'http://localhost/');
*** Error 42000: [OpenLink][Virtuoso ODBC Driver][Virtuoso Server]SR598:
TURTLE
parser has failed to open file 'C:♂
irtuoso-opensourceDBpediarticlecategories_en.
n3' for reading
at line 38 of Top-Level:
DB.DBA.TTLP_MT_LOCAL_FILE
('C:\virtuoso-opensource\DBpedia\articlecategories_en.
n3', '', 'http://localhost/')
Any suggestions here would be appreciated. I'm still very new to the
Virtuoso server, so I may be overlooking something major here.
Regards,
Alex

Hi Alex,
Are you uploaded these 4GB files via WebDAV ? You might want to try
the Virtuoso TTLP family of functions for uploading such large
datasets as detailed at:
