Thanks, this works as advertised! But how can I decide, which datasets
are ready for production use (e.g. to select the four relevant datasets

    dc:title "Benchmark Data Set for in Silico Prediction of Ames Mutagenicity" ;
    dc:title "Bursi mutagenicity dataset.sdf" ;
    dc:title "CPDBAS: Carcinogenic Potency Database Summary Tables - All Species" ;
    dc:title "ISSCAN: Istituto Superiore di Sanita, CHEMICAL CARCINOGENS: STRUCTURES AND EXPERIMENTAL DATA" ;

from 247 mutagenicity datasets), if I do not know titles in advance?

I have also observed that the dataset counts from
http://apps.ideaconsult.net:8080/ambit2/query/ndatasets_endpoint differ
sometimes from the number of datasets retrieved by
http://apps.ideaconsult.net:8080/ambit2/dataset?feature_sameas=<echa_entry>.
(Acute_toxicity_to_fish_lethality 15 vs 208, Mutagenicity 247 vs 248).

Best regards,
Christoph
