[Virtuoso-users] New OpenLink Community Site
To all our users, customers, partners, and friends — (You can see a more detailed version of this announcement in our Medium-hosted blog space, at [0].) With excitement, we present our brand-new Discourse-powered [1] Community Site and Discussion Forum, at community.openlinksw.com. [2] This is a place to ask questions about and help others with our SQL, ODBC, JDBC, ADO.NET, OLE DB, SPARQL, RDF, HTTP, WebDAV, LDP, TLS, OAuth, and OpenID Connect compliant products and technologies, as well as to share projects you’ve worked on and to collaborate locally. This new discussion space includes built-in features like Web Pages that double as launch-points to a Semantic Web of Linked Data, courtesy of embedded descriptions of actions (e.g., “Search”) that are comprehensible by both humans and machines, enabling discovery and REST-ful interaction via the combined effects of tools such as our own Virtuoso RDBMS, Data Transformation Middleware (Sponger), OSDB (OpenLink Smart Data Bot) and OSDS (OpenLink Structured Data Sniffer). Please use one of your social logins (such as Twitter, Facebook, or LinkedIn) to create an account, and introduce yourself. An introductory post is a good way to start in this community. Who are you, where do you live and work, what brought you to these technologies, and to OpenLink Software…? Before posting a question, please search the site [3] to see whether it’s been asked before. If existing answers don’t quite fit your situation, use your best judgement about asking a new question or following up to an existing thread. When you ask questions, please try to post them to the correct category. Additional tags can also be helpful to others trying to find answers, and trying to help users like you. In your questions, please share as much detail as possible, so that others can understand and reproduce your issue. For instance, if you’re asking about an ODBC issue, be sure to provide the specific driver edition, name, and version, as well as the name and version of the ODBC application and host OS, and of the target DBMS. If you know them, anchoring elements of your question with relevant Linked Data URIs can help ensure everyone is talking about the same thing. (If you’re concerned about privacy for any reason, our Support Center and confidential Case System [4] remains available, but will generally be handled at lower priority unless you have a current Support Contract.) If you have any questions about the Community site itself, please raise them in the Feedback category. [5] Please enjoy!

You mean the following fails?
curl --cert {pkcs#12-file}.p12:1234 --cert-type P12 -X POST
-H'Content-Type: text/turtle' \
-d '<#this> <#relatedTo> <#that> .' {URI-of-LDP-Folder}/test.ttl
If so, please run the following command and then try again:
WEBDAV.DBA.ldp_recovery_aq ('/DAV/{ldp-enabled-folder}')
If that procedure doesn't exist, please create it by running the
following via iSQL UI in the Conductor:
CREATE PROCEDURE ldp_recov (in fld varchar)
{
DECLARE id int;
DECLARE path any;
id := DAV_SEARCH_ID (fld, 'C');
IF (NOT LDP_ENABLED (id))
RETURN;
FOR SELECT COL_NAME FROM WS.WS.SYS_DAV_COL WHERE COL_ID = id DO
{
DECLARE s, uri, path any;
uri := WS.WS.DAV_IRI (fld);
TTLP ('@prefix ldp: . <> a
ldp:BasicContainer, ldp:Container .', uri, uri);
FOR SELECT RES_CONTENT, RES_FULL_PATH FROM WS.WS.SYS_DAV_RES WHERE
RES_COL = id AND RES_TYPE = 'text/turtle' DO
{
DECLARE ruri any;
ruri := WS.WS.DAV_IRI (RES_FULL_PATH);
TTLP (sprintf ('<%s> <%s> .',
uri, ruri), uri, uri);
{
DECLARE continue handler for sqlstate '*';
TTLP (CAST (RES_CONTENT as varchar), ruri, ruri, 255);

ruri := WS.WS.DAV_IRI (path);
TTLP (sprintf ('<%s> <%s> .',
uri, ruri), uri, uri);
}
}
FOR SELECT COL_NAME FROM WS.WS.SYS_DAV_COL WHERE COL_PARENT = id AND

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?

All,
You need to install the ODS-Framework [1] and ODS-Briefcase [2]
modules
atop your Virtuoso instance. Net effect, it adds an LDP layer to the
Virtuoso WebDAV core.
Once installed, you can simply perform the following verification
tests.
Setup verification tests:
1. curl -X OPTIONS -IH "Accept: text/turtle" {URI-of-LDP-Folder}
2. curl -iH "Accept: text/turtle" {URI-of-LDP-Folder}
If the above is successful, you can perform some based read-write
tests:
JSON-LD:
curl --cert {pkcs#12-file}.p12:1234 --cert-type P12 -X POST -H
'Content-Type: application/ld+json' \
-d '[{"@id":"","http://schema.org/name":"Foo"}]'
{URI-of-LDP-Folder}/test.jsonld
RDF-Turtle:
curl --cert {pkcs#12-file}.p12:1234 --cert-type P12 -X POST
-H'Content-Type: text/turtle' \
-d '<#this> <#relatedTo> <#that> .' {URI-of-LDP-Folder}/test.ttl
VOS requires a different version of the ODS packages in order to work:

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!
