If you refer to opentox-client examples, then RDFRepresentation is not a
Restlet class at all, but custom one, using Jena writers for serializing
RDF.

https://ambit.svn.sourceforge.net/svnroot/ambit/branches/opentox/opentox-client/src/main/java/org/opentox/rdf/representation/RDFRepresentation.java

Restlet RDF support is rather minimalistic (graph representation, no
querying, let alone reasoning), I am not sure if any of the partners
actually uses it. If you are working with 1.x Restlet , there is indeed no
RDF support there. But Restlet RDF support can be safely ignored if you are
already using Jena (though I would be curious to see performance comparison
between the two).

Using StringRepresentation/ FileRepresentation with media type
"application/rdf+xml" does the same job.  RDFRepresentation class discussed
above actually creates OutputStreamRepresentation.

Upload examples can be found here

The examples above are cleaned up versions of ambit code. JUnit tests of
ambit dataset services can be found here

Here is a summary

curl -X POST -d "@filecontent" -H "Content-type:application/rdf+xml"
http://datasetservice/dataset

This returns Task object (either URI, if -H "Accept:text/uri-list" is
specified or Task RDF representation if -H "Accept:application/rdf+xml" is
specified).  Task RDF representation is defined in
http://opentox.org/api/1_1/opentox.owl

If the task is still running you'll get result codes 201 or 202 , this means
you need to query again the returned task URI.  If code 200 is returned, the
URI returned is where the result should be found.   In the examples there is
a RemoteTask class that handles all this.

For testing

http://ambit-uni-plovdiv.bg:8080/ambit2/dataset

For your final models/results , especially if you would like them appearing
in ToxPredict.

http://apps.ideaconsult.net:8080/ambit2/dataset

See above.

Hope this helps,
Nina
