Hi Everyone, Since I haven't received replies in last 10 days and the open issues are for me now very blocking I just refresh my currently still open questions trying to simplify the explanation. I have a local application on my machine that is invoked with a couples of argument (for example 2 strings), do it's processing and create some results (more or less complex). Is it possible to wrap the execution of my local application with airavata in such a way that i can register the application on my local airavata-server and subsequently create experiments using the airavata-generated application interface? How should the application invocation arguments be translated when I create the application interface? How can I get as output of experiment the results of my applications? Which are the steps that I should follow?
Thank you again and sorry for my harassment but these questions have become completely blocking in the last days...

Thanks again for your support, Alfredo Date: Thu, 13 Nov 2014 10:12:25 -0500 Subject: Re: Questions about Custom Application Registration and Complex Input/Output Data From: [email protected] To: [email protected] Hi Alfredo, I will answer this easier one first. You guessed it right, as it stands now, the token is a handle to a credential which is used for compute resources. As for local resources, we can pretty much send something and i will get ignored. The current token is described in a paper by Amila Jayasekara described at [1] or [2] for a direct link. One of the many reasons Airavata is holding up on a 1.0 release is to clear usage of the API in a secured way. In general, we are modeling similar to how Evernote uses Thrift API [3]. We recently had a good long review in this context by experts [4], we will soon have a technical paper describing Airavata API security and identity management and should have a implementation soon there after.

In the samples are hard-coded values.. are they really influent? At least using localhost as computeHost it's unnecessary to use/generate them right?
