Hi Alessandro.
Sorry for the late reply.
Thanks a lot for your help in this. I read your last mail about the
Clerezza update, nevertheless I'll answer to this earlier mail. I'll go
through the mail step by step.

Off the top of my head, and given the type of exception that you
received, I think Rupert is right. But to confirm that I need numbers.
How many ontologies have you been trying to upload since first running
Stanbol, and how large?
only one ontology:
http://ontologydesignpatterns.org/ont/iks/kres/omv.owl (~ 100KB)
I have only started looking at the ontonet endpoint, and failed when
trying to load that one for testing.
Can you check the size of your TDB data directory? from the felix
console you have to note the bundle number of the "Clerezza - SCB Jena
TDB Storage Provider" bundle (let it be N).
that should be 13 for me
Then check the size of directory
[sling-launcher-dir]/stanbol/felix/bundle[N]/data/tdb-data
that's
stanbol/felix/bundle13/data/tdb-data
size is 11 M

If it is as I expect, it is a Clerezza/TDB issue and we need to wait
until named graph support in Jena TDB goes into the Clerezza mainline.
As for these:
curl -i -X PUT
"http://<myserver>/ontonet/ontology/<scopeID>?location=http://ontologydesignpatterns.org/ont/iks/kres/";
This is incorrect, there is no "location" parameter in the PUT, and
the URI you supplied is neither a regular ontology nor a registry
definition, but just a directory. That PUT works anyway, but it
creates an empty scope (which is acceptable btw)
thanks.
Would you like a variant that tries to load all the ontologies in a
(remote) directory? That would only work if the HTTP server allows
directory listing though.
An example of a library being loaded on scope creation is:
curl -X PUT
http://<myserver>/ontonet/ontology/<scopeID>?corereg=http://stanbol.apache.org/ontologies/registries/stanbol_network/SocialNetworks
curl -i -X POST -data
"http://ontologydesignpatterns.org/ont/iks/kres/omv.owl";
http://<myserver>/ontonet/ontology/<scopeID>
That gave me some Unsupported Media Type Error
because that way (using --data) you should supply the ontology content
in the payload, not its URL
If you want to just give it the url, you have to use the
form-multipart variant:
curl -X POST -F
"url=http://ontologydesignpatterns.org/ont/iks/kres/omv.owl";
http://<myserver>/ontonet/ontology/myScope
yes thanks, I tried this morning.
Even better, if you know the format you can also add the form
parameter "format" with the MIME Type, otherwise it will try to guess
among supported formats (there is still a bug for Turtle due to the
usage of the non-registered MIME type).
Perhaps you've looked at some outdated documentation that I should
update?
I mainly looked at the REST API, and also at the documentation on
http://incubator.apache.org/stanbol/docs/trunk/
Also, don't forget that before starting to load ontologies, you should
configure the namespace of the Ontology Network Manager and the
Session Manager in the Felix console, so that they point to the
resolvable URLs. This is necessary for the Java API to produce correct
import statements.
OK, I did not know that. I just checked, it's set to
http://localhost:8080/ontonet/
*hmpf*, that explains why I keep seeing this localhost address whenever
working with the ontonet endpoint. Sorry for this.
What is to be specified here? Just insert my server address, so that it's
http://<myserver:port>/ontonet
?
Best
Melanie
