Christoph,

Indeed there are no dataset features registered in the ontology service. We
might register some of course.

The query I am using in  ToxPredict is

http://apps.ideaconsult.net:8080/ambit2/dataset?feature_sameas=http%3A%2F%2Fwww.opentox.org%2FechaEndpoints.owl%23AcuteInhalationToxicity


or in general :

http://apps.ideaconsult.net:8080/ambit2/dataset?feature_sameas=<urlencoded
entry from ECHA endpoints ontology>


There is also a set summary queries (recently introduced and not yet
announced on the list), which are not in the API yet , but may be it make
sense to include them somehow and invent RDF serialisation (there is only
text/csv and text/html so far).

http://apps.ideaconsult.net:8080/ambit2/query/ndatasets_endpoint

Hope this helps,
Nina
