Well your choices are limited:
1. Either the data contains the axioms already (mix like in OWL test cases)
2. Data contains "owl:imports"
3. You add the links to the ontologies via the http parameters (there is
no reason, why this shouldn't work as an array except "not implemented yet")
4. Download the most common ontologies (FOAF, etc. ) and use them per
default within the component or provide a mechanism to download and
cache them on demand, e.g. by:
"curl http://xmlns.com/foaf/0.1/knows";
Other than that I wouldn't know how your reasoning component would get
the necessary knowledge to draw conclusions.
(Note that I am a complete Stanbol newbie, but this is how all other
frameworks I know work)

Hi Sebastian
Thanks for your mail. The parameter array proposal seemed promising
but unfortunately it doesn't work. The second url-parameter is simply
ignored.
My example shouldn't be about inference in general but on how stanbol
components can be used to do something useful with cms data or with
data out there on the web. So crafted example documents
unrealistically mixing instance data with t-box ontology or w3c test
cases are not an option.
A couple of curl commands showing something that goes into the
direction of the example describen in "Knowledge within content" on
https://stanbol.apache.org/docs/trunk/components/ontologymanager/
would be fine as well.
Cheers,

Hi Reto,
you can use the OWL test cases:
http://www.w3.org/TR/owl-test/
(I am not sure, whether RDFS has the same... )
They have nice minimal examples:
http://www.w3.org/2002/03owlt/TransitiveProperty/
e.g http://www.w3.org/2002/03owlt/TransitiveProperty/premises001.rdf
concludes:
http://www.w3.org/2002/03owlt/TransitiveProperty/conclusions001.rdf
Actually for your webservice you should be able to add the schema
as well, maybe via a parameter array:
http://localhost:8080/reasoners/rdfs/classify?url=http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf&uri=http://xmlns.com/foaf/spec/index.rdf
Normal, the data doesn't have an owl:imports statement, so you can
not assume that this is given.
All the best,
Sebastian

Hello,
I'm trying to create a simple demo for OntologyManager and/or
Reasoner.
I thought that it might be nice to show how by rdfs entailment
on the
rdfs:range of the foaf:knows properties we could add missing
rdf:type
statements to http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf
Just getting
http://localhost:8080/reasoners/rdfs/classify?url=http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdfdoesn't
<http://localhost:8080/reasoners/rdfs/classify?url=http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdfdoesn%27t>
add these statements. Probably because it doesn't know about the
rdfs:range of foaf:knows.
Is there an easy way to do this?
I would also be open to other's suggestion on how to show
ontologynetwork
and/or reasoner features with a couple of curl invocations or
lines of js
code. Unfortunately for now the only thing I've found our
Adrian Gschwend's
IKS Evaluation which basically shows how to use the
ontologynetwork as a
cache/proxy for ontology. This seems to be quite little with
respect to
what these components should be able to do.
Cheers,
Reto
