As it could be seen, finally the URI of the dataset with MNA descriptors is
returned, so it works fine. However, the dataset representation, SMILES
string and anything, which is not ot:Task  representation and is returned
from the first POST call, should not be there.

Another comment is the MNA/QNA descriptor calculation is returning Task URI
only after all the processing is completed and results sent to the dataset
service. This means , the HTTP POST call may not complete for long time, if
the dataset to be processed  contains more than few compounds.  OpenTox API
recommends to return task URI immediately after accepting the processing,
and then the client polls the task URI to find if it is completed.

I have not tested how well the services work if sending multiple requests in
parallel, would be better if you agree to setup smokeping testing for this
purpose.

I guess the best way to handle custom formats for feature values content (in
addition to standard string and number types ) is to propose specific MIME
format and document them at OpenTox site. There might be better ways, would
be good to discuss during today meeting.

I hope Christoph could answer ToxCreate and lazar related questions.
