Thanks! I have tried with

curl -X POST -d dataset_uri=http://ot-dev.in-silico.ch/dataset/356 -d model_uri=http://apps.ideaconsult.net:8080/ambit2/algorithm/J48 http://apps.ideaconsult.net:8080/ambit2/algorithm/superservice

which returns the RDF (not task URI):

I guess, I would have to specify also the target feature URI
(http://ot-dev.in-silico.ch/toxcreate/feature#hamster_carc in this
case), how would I do that?
