Hi Garry
Your first curl command seems very similar to what I've been doing with
my webdav client (konqueror) except that you're putting to home/demo
rather that home/dav as I did. If I understand things correctly PUTting
to the rdf_sink should make the triples directly available Still it
doesn't work for me with konqueror nor with curl.
That's how the communication looks like with konqueror:
PUT /DAV/home/demo/rdf_sink/University0_14.owl HTTP/1.1
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.7
(like Gecko)
Pragma: no-cache
Cache-control: no-cache
Accept: text/html, image/jpeg, image/png, text/*, image/*, */*
Accept-Encoding: x-gzip, x-deflate, gzip, deflate
Accept-Charset: iso-8859-1, utf-8;q=0.5, *;q=0.5
Accept-Language: en
Host: localhost:8890
Authorization: Basic ZGF2OmRhdg==
Connection: Keep-Alive
Content-Length: 442158
<?xml version="1.0" encoding=."UTF-8" ?>
<rdf:RDF
....
The transcript of a CURL upload looks like this:
PUT /DAV/home/demo/rdf_sink/University0_7.rdf HTTP/1.1
Authorization: Basic ZGJhOmRiYQ==
User-Agent: curl/7.16.4 (i686-pc-linux-gnu) libcurl/7.16.4
OpenSSL/0.9.8g zlib/1.2.3
Host: localhost:8890
Accept: */*
Content-Length: 599509
Expect: 100-continue
HTTP/1.1 100 Continue
<?xml version="1.0" encoding="UTF-8" ?>
<rdf:RDF
....
Interestingly the latter creates a resource called
http://localhost:8890/DAV/home/demo/rdf_sink/http___localhost_8890_DAV_home_demo_rdf_sink_.RDF,
which seems against the RDF 2616 PUT semantics " The PUT method requests
that the enclosed entity be stored under the supplied Request-URI".
However I can't seem to successfully run sparql queries against any of
the created URIs, for example
GET
/sparql?default-graph-uri=http%3A%2F%2Flocalhost%3A8890%2FDAV%2Fhome%2Fdemo%2Frdf_sink%2Fhttp___loca
lhost_8890_DAV_home_demo_rdf_sink_.RDF&should-sponge=&query=SELECT+*+WHERE+%7B%3Fs+%3Fp+%3Fo%7D&format=text%2Fhtml&debug=on

What am I missing?

Hi Reto,
You can refer to the following URL for information regarding inserting RDF
data into virtuoso -
http://virtuoso.openlinksw.com/wiki/main/Main/VirtRDFInsert
This Wiki page is still a work in progress so if you require any further
information, please ask?
Also, the following examples may help --
curl -T myfoaf.rdf
http://demo.openlinksw.com/DAV/home/demo/rdf_sink/myfoaf.rdf
curl -i -d "INSERT {<s> <p> <o>}" -H "Content-Type:
application/sparql-query" http://host:port/DAV/xx/yy
Finally, apologies, I was not in receipt of you original mailing list mail
so I was unable to reply in the conventional means.
Regards,
Garry M. Biggs
