Hi Adrian,
I am not well-versed with the contenthub, so I can guess it depends on
what policies it has for inspecting graphs and selecting them by name.
Does your r2HR.rdf have a logical OWL ID? (in RDF, it is the name of a
singleton instance of owl:Ontology) If the ontologymanager shows a
file:/// URI, probably not. In that case, off the top of my hat it might
just be that the contenthub filters it out because of an unconventional
graph name.

Hi Alessandro,
Thank you so much for the detailed explanation, your example worked!
May I ask one more question please: I also loaded my locally stored
ontology called 'r2HR-ontology' stored in a file r2HR.rdf
At http://localhost:8080/ontonet under 'Stored ontologies' shows both
file:///C:/Users/r2HR.rdf/r2HR-ontology
http://www.ontologydesignpatterns.org/cp/owl/agentrole.owl
However, at http://localhost:8080/contenthub/contenthub/search/featured
under 'Graph: Choose ontology' only agentrole.owl is available, r2HR.rdf is
not present.
Why is this?
Thanks again,
Adrian

Objet : Re: Load ontology to scope -- does not work
Hi Adrian,
that documentation you looked at is outdated and no longer a reference for
Stanbol services.
It seems like the preferred way to manage an ontology in a scope is the
first create it in the ontologymanager, then attach it to the scope.
Remember that ontology management is a privileged action so you need HTTP
authentication (I'm using the default admin:admin here, which of course you
should change in production).
This is the sequence that worked for me:
# Load external ontology
$ curl -u admin:admin -X POST -F
"url=http://www.ontologydesignpatterns.org/cp/owl/agentrole.owl";
http://localhost:8080/ontonet
# Create scope
$ curl -u admin:admin -X PUT
http://localhost:8080/ontonet/ontology/r2HR
# Tell the scope to manage the ontology (use text/plain) # Request body is
the logical ID of the ontology, which in this case matches with the URL it
came from
$ curl -u admin:admin -X POST -H "Content-type: text/plain" -d
"http://www.ontologydesignpatterns.org/cp/owl/agentrole.owl";
http://localhost:8080/ontonet/ontology/r2HR
Still, it is true that the REST API and HTML interface of the ontology
manager need to be refreshed.
best

Hi Adrian,
I am not in front of a Stanbol installation right now so I will
double-check that, but I think that since security was introduced in
Stanbol, loading ontologies has become a privileged action that
requires HTTP authentication. If you have not created custom users or
set new passwords, try the same command with -u
curl -u admin:admin -X POST -F
location="http://www.ontologydesignpatterns.org/cp/owl/agentrole.owl";
http://localhost:8080/ontonet/ontology/r2HR
If it works, it should be a more feasible alternative to starting
stanbol with the -no-security option
I will try that out myself asap

Oggetto: Load ontology to scope -- does not work
I have a scope called 'r2HR' and I try to load an ontology,
http://www.ontologydesignpatterns.org/cp/owl/agentrole.owl , for
testing purposes. This ontology is mentioned in the examples at
http://stlab.istc.cnr.it/documents/KReS/KReS-Alpha/node25.html
I use
curl -X POST -F
location="http://www.ontologydesignpatterns.org/cp/owl/agentrole.owl";
http://localhost:8080/ontonet/ontology/r2HR
and the response is
<html>
<head>
<meta http-equiv="Content-Type"
content="text/html;charset=ISO-8859-1"/>
<title>Error 400 Bad Request</title>
</head>
<body>
<h2>HTTP ERROR: 400</h2>
<p>Problem accessing /ontonet/ontology/r2HR. Reason:
<pre> Bad Request</pre></p>
<hr /><i><small>Powered by Jetty://</small></i>
</body>
</html>
The same response I get when I try to load the ontology via the web
interface (i.e. Load an ontology -> From a URL -> Fetch )
In the Stanbol's command window (DOS) no related information is displayed.
Can anyone please tell me how to upload the ontology to the scope ?
Thanks, Adrian
