Hi Jeff,
have a look here:
http://docs.openlinksw.com/virtuoso/rdfapiandsql.html
Section: 14.2.2.1 Data Import
you should be able to import your data using command
line tool 'isql'.
BTW, I suspect there may be a bug related to RDF
import
(or maybe I did something wrong), I had better results
importing ntriples data.
Regards,
Anton

The Virtuoso RDF FAQ
(http://virtuoso.openlinksw.com/wiki/main/Main/VOSRDFFAQ)
says that RDF
files can be imported via WebDAV:
How Do You Put RDF Data Into Virtuoso?
Virtuoso provides several load or data import
functions that insert
data into the triple store. These include:
* Copy RDF files into WebDAV after mounting
Virtuoso's WebDAV
repository via your operating systems WebDAV
filesystem mount feature
.....
I am trying to accomplish just that, but am having
no success. Also I
can't find any more documentation other than the
snippet from the FAQ
above.
I am using Virtuoso 4.5.4 Open Source on Linux
(Redhat AS4).
First of all, I can't imaging why "mounting" the
WebDAV repository
should make any difference. I am using cadaver to
"put" my RDF files,
and then I do the following SPARQL query:
SQL> sparql select * where { graph ?g { ?s ?p ?o } }
What do I need to do to get Virtuoso to index my RDF
files and store
them in the RDF database?
Is there any other documentation that describes how
to do this?
Thanks,
Jeff

All,
A few things re. Virtuoso and RDF:
1. There is a new release 4.5.6 coming out in the next few hours that
will include the following methods for RDF I/O re. Triple Store:
- Semantic Bank API (HTTP Based)
- RDF NET API (HTTP Based)
- OpenLink Data Spaces (ODS) Briefcase UI which has an "Upload to
Triple Store" link that facilitates RDF uploads to Triple Store
2. When you drop RDF files into Virtuoso's WebDAV it will also
automatically discern the metadata of the WebDAV resource and write this
to the Triple Store. The problem here is that no Triples from within the
graph itself are picked up (which is where the items listed above come
in; ditto the exist Virtuoso PL based APIs for Triple Store I/O).
I would suggest you use 4.5.6 with the ODS VAD packages installed.
To see a live demo of this ODS feature for uploading Graphs you can go to:
http://demo.openlinksw.com/ods or http://myopenlink.net:8890/ods
(register and then create an ODS-Briefcase instance).
