[Virtuoso-users] PATCH metadata of a LDP Container
Hi all!
Attempting to follow the patterns on:
https://medium.com/virtuoso-blog/http-read-write-operations-using-ldp-protocols-virtuoso-http-s-server-bdaa2736169f
I have an LDP Container http://my.server/LDP/Container1
in the SPARQL endpoint, the URI of the container is the named graph,
typed as ldp:Container
I want to add metadata to that container. I am guessing that I need to
use PATCH and the sparql INSERT query, but I am constantly getting 409
errors (HTTP/1.1 409 Conflict: can not create resource if a collection
with same name exists)
This is (excluding username/password) what my PATCH request looks like:
curl -v -g -X PATCH -ik -H "Content-Type:
application/sparql-update:utf-8" -u user:pass --data-binary 'INSERT
{GRAPH
Re: [Virtuoso-users] Can't create ldp:Resource from Turtle file
Hi Kingsley,
Yes, as I indicated in my initial message, I started-out using just the
Conductor/Content-Management route. I activated the "enable LDP"
button, and was pleased that I was able to do almost every LDP
operation... *EXCEPT* to create an RDF resource (failed parse of turtle)
All other LDP functionality was working exactly as I expected, simply by
activating the "enable LDP" checkbox. Only the creation of RDF
Resources fails.

If I simply attempt to interact with (via LDP curl calls) the Public

So... I'm not making a lot of progress.
Suggestions?

You don't really need to take the ODS-Briefcase route into this
LDP/WebDAV realm. You can also get their via the Conductor. Thus, when
you get in via the Conductor UI ("Content Management" menu item) do you
see the "enable LDP" button associated with the property lookup on a
folder?

Setup verification tests:
1. curl -X OPTIONS -IH "Accept: text/turtle" {URI-of-LDP-Folder}

Re: [Virtuoso-users] Can't create ldp:Resource from Turtle file
Thanks, I'll try that later today.
MIght be worthwhile adding these instructions to the manual page
describing LDP, as neither the requirement for ODS, nor the different
packages for OS vs Enterprise are described there.
Cheers!

[Virtuoso-users] Can't create ldp:Resource from Turtle file
Hi all, I'm following the instructions at http://vos.openlinksw.com/owiki/wiki/VOS/VirtLDP and am not having much joy. (Virtuoso 7.20) A few things: in Conductor, steps 3 and 4 of "enable LDP on folder" - the screenshots don't match what I see. I have an additional checkbox for "LDP enable/disable" (which I have set to "on"). I am unable to set properties LDP = ldp:BasicContainer as indicated in the instructions. The LDP property is not in the dropdown list, and if I type it manually and press "update" it doesn't stick - it isn't there the next time I look at the properties. I'm guessing that it is working (??) because I can create LDP containers as expected... but it's disconcerting. I am, however, unable to create an ldp:Resource from a turtle file. Every Turtle file I try to send (Content-type: text/turtle) fails with a HTTP 500: SP029: TURTLE RDF loader, line 1: syntax error (both PUT and POST). (There is no syntax error in my turtle file - I have tried with several, including sample files from W3C) I am able to create an ldp:Resource that is plaintext (Content-type: text/plain header), and the container correctly gets the additional "contains" property, so that seems to be working well! Any advice on creating RDF resources? Thanks! Mark ___ Virtuoso-users mailing list Virtuoso-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/virtuoso-users
