Hi Melanie,
sorry for the late reply but I was on a short leave right after the
Salzburg workshop

btw: the ontology libraries unter ontonet/registry, they link to

http://stanbol.apache.org/ontologies/registries/stanbol_network/Foundational).
Are they located somewhere else now?
Yes, the actual library definition (in a registry) is in a Stanbol
default data bundle running on your launcher
(org.apache.stanbol.data.registries.default)
We are using that namespace in anticipation of the Stanbol graduation.
We expect to be able to load ontologies into
http://stanbol.apache.org/ontologies/ once Stanbol graduates. While we
wait for that, we use the Stanbol data file provider.

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?
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).
Then check the size of directory
[sling-launcher-dir]/stanbol/felix/bundle[N]/data/tdb-data
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)
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
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?
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.
I'm trying to figure out a way not to need that anymore, but it must
work even if the RESTful API is not used (so you cannot register the
UriInfo as a namespace).
Anyway I'm working on quite a few enhancements on the ontology network
structure persistence, will commit this when it's done (hopefully I'll
be able to resume development today or tomorrow).
