Hi Taalai,
Hi all,
I have created user "tman" with password gxa
and upload rdf file using:
$ curl -i -T myTriples.rdf
http://localhost:8890/DAV/home/tman/rdf_sink/myTriples.rdf
-u tman:gxa
(and also tried uploading using webDAV browser)
and got the result
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//
EN"><HTML><HEAD><TITLE>201 Created</TITLE></HEAD><BODY><H1>Created</
H1>Resource /DAV/home/tman/rdf_sink/myTriples.rdf has been created.</
BODY></HTML>
the WebDAV Browser shows me that the file is there
but when I run query (using end point, tereminal and even internal
SPARQL execution)
default graph uri is : http://localhost:8890/DAV/home/tman/rdf_sink
query:
select * where {?s ?p ?o} (I tried many different queries)
returns empty table
s-p-o
same happens when I run query form terminal
curl -F "query=SELECT DISTINCT ?p FROM
<http://localhost:8890/DAV/home/tman/rdf_sink/
> WHERE {?s ?p ?o}" http://localhost:8890/sparql
What can be the reason for that?
Here is what I performed (for ex. on a clear db). Please give us more
details if
you are doing different than these steps:
1. install ods, briefcase and conductor packages
2. login at conductor as dba (http://host:port/conductor)
3. go to System Admin->User Accounts->Create New Account
4. In the shown form:
- enter for Account name/User Login tman, enter and re-type pwd,
- enter for DAV Home Path: /DAV/home/tman/ and check "create"
- change user type to WebDAV
- click Save
5. now execute:
$ curl -i -T TimBLcard.rdf
http://host:port/DAV/home/tman/rdf_sink/TimBLcard.rdf -u tman:gxa
Note that host:port is the value of DefaultHost in your virtuoso ini,
section [URIQA].
6. The results I got:
HTTP/1.1 100 Continue
HTTP/1.1 201 Created
Server: Virtuoso/05.12.3041 (Win32) i686-generic-win-32 VDB
Connection: close

Created</TITLE></HEAD><BODY><H1>Created</H1>Resource
/DAV/home/tman/rdf_sink/
TimBLcard.rdf has been created.</BODY></HTML>
7. As result the data will be inserted in the graph
<http://host:port/DAV/home/tman/rdf_sink/> and also the TimBLcard.rdf will
be uploaded to the DAV location DAV/home/tman/rdf_sink in the Virtuoso
Server.
* note you can view your user's WebDAV resource content by:
1. Using Conductor->Web Application Server->Content Management
(http://docs.openlinksw.com/virtuoso/htmlconductorbar.html)
2. Using ODS Briefcase UI (see more details here:
http://ods.openlinksw.com/dataspace/dav/wiki/ODS/OdsBriefcase)
8. Check the inserted triples using curl or directly from ISQL:
curl -F "query=SELECT DISTINCT ?p FROM
<http://host:port/DAV/home/tman/rdf_sink/> WHERE {?s ?p ?o}"
http://host:port/sparql
with result:
<sparql xmlns="http://www.w3.org/2005/sparql-results#";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.w3.org/200
1/sw/DataAccess/rf1/result2.xsd">
<head>
<variable name="p"/>
</head>
<results distinct="false" ordered="true">
<result>
<binding

</result>
<result>
<binding
name="p"><literal>http://purl.org/dc/elements/1.1/title</literal></binding>
or from ISQL:
SQL>SPARQL
SELECT DISTINCT ?p
FROM <http://host:port/DAV/home/tman/rdf_sink/>
WHERE
{
?s ?p ?o .
}
;
p
VARCHAR

BTW, how big is the file you are uploading?
As for million of triples we highly recommend for faster loading to use the
RDF_LOAD_RDFXML_MT () function ( see for reference:
http://docs.openlinksw.com/virtuoso/fn_rdf_load_rdfxml_mt.html )
