Hi Kingsley,
Where is the FROM in the SPARQL?
I didn't know it was required. Issuing the query at
http://localhost:8890/sparql with no FROM does return some data, so I
assumed that there was some default scope for the query, and that for
user3 it would be any data accessible by that user.
As you'll see from my followup to Rumi I tried some IRIs, which were
probably the wrong ones, because I still couldn't get it to work.
Graph IRI should be the IRI/URL of the RDF file in DAV which is not
used as Graph IRI inside the Quad Store for the data from the RDF
info. resource.
I don't follow you there. "which is not used as the Graph IRI inside
the quad store"?
Is this (identification of proper IRI, etc.) covered in any particular
place in the documentation?
thanks,
Bob,
Errr. you caught an internal digital scribble full of shorthand :-(
It wasn't really a public comment :-)

Thanks Rumi, that worked! Before, I hadn't checked "Allow SQL/ODBC
Logins,"and I thought /DAV/home// was a default value for "DAV Home
Path" and didn't realize what I was supposed to do with it--I guess
I assumed that a home/username directory would be created based on
the login ID name, and I also missed the "Create" checkbox there. I
created user3:pw3 as the account with the following,
curl -i -T myfoaf.rdf
http://localhost:8890/DAV/home/user3/rdf_sink/myfoaf.rdf -u user3:pw3
and got "Resource /DAV/home/user3/rdf_sink/myfoaf.rdf has been
created."
Now, I'm trying to query that data. I tried this (on one line) and
got an HTTP 201 ("Created") but it didn't t show me any results of
the query.
curl -i -u user3:pw3 -H "Content-Type: application/sparql-query"
-d "SELECT DISTINCT ?p WHERE {?s ?p ?o}"
http://localhost:8890/DAV/home/user3/rdf_sink/myfoaf.rdf
Where is the FROM in the SPARQL?
When I went http://localhost:8890/sparql after logging on as user3,
the query "SELECT DISTINCT ?p WHERE {?s ?p ?o}" only showed me
predicates in the http://www.openlinksw.com/schemas/virtrdf#
namespace and none from the myfoaf.rdf file. I tried specifying
http://localhost:8890/DAV/home/user3/rdf_sink/myfoaf.rdf as the
graph name to retrieve from, but then the query retrieved nothing.
I have a feeling that I'm just missing some tiny detail...
Yes FROM GRAPH IRI.
Graph IRI should be the IRI/URL of the RDF file in DAV which is not
used as Graph IRI inside the Quad Store for the data from the RDF
info. resource.

Hi Bob,
Thanks Hugh!
Any suggestions about point 2?
Here is what I performed locally on winxp installation:
1. Go to Conductor and click "Create New Account"
2. Enter account name: user11 and also enter pwd, for ex.: 1
3. Check "User Enabled" and "Allow SQL/ODBC Logins"
4. Add roles SPARQL_SELECT and SPARQL_UPDATE
5. Check "Allow DAV logins"
6. Enter for "DAV Home path": /DAV/home/user11/
7. Check the "create" check-box.
8. Click "Save".
Then I've executed this (being in the folder where I have a
myfoaf.rdf file):
$ curl -T myfoaf.rdf
http://host:port/DAV/home/user11/rdf_sink/myfoaf.rdf -u user11:1
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML
2.0//EN"><HTML><HEAD><TITLE>201
Created</TITLE></HEAD><BODY><H1>Created</H1>Resource
/DAV/home/user11/rdf_sink/myfoaf.rdf has been created.</BODY></HTML>
Hope this to help.
Best Regards,
Rumi
