I guess you mean MNA service downloads the dataset ?  How do you check the
"presense" of the dataset ? If you do GET , it is already a download of
dataset, and if I understood right, you are actually doing two GET requests
on this dataset?

e.g. you send the user and password to the OpenSSO Policy service and
receive an OpenSSO token ?  If yes, you should do this as a first step,
otherwise when our server will go protected, you will not be able to
retrieve the data.

Or did I misunderstood ?

MNA service sends POST request to ambit.uni-plovdiv server to upload
calculated descriptiors, right ?

It is not quite clear to me, but in general, the (MNA) service should have
already send the data for upload and just polling the task.  It is not
necessary to wait for the task completion, neither to retrieve the result
dataset.

That's definitely not the most efficient way.

Why not just storing the entire RDF of the dataset locally , until it is
completed , and then post the RDF to the dataset service.  Just one POST and
not need to listen to task completion at all.
