>Hi all,

>1. Clients (users) can push input files and metadata to file server (OODT

>provide to Airavata
>2. Users submit experiments to Airavata with the url of uploaded input
>3. Airavata should be able to fetch the input file over SCP or some other

> 4. Once the experiment (job) is done, Airavata should be able to push
>output files to file server and notify the client.
>5. Client should be able to download the output file.
>In addition to that, enforcing security in uploading and downloading

>1. Can OODT file manager simulate the role of file server that I have

>2. Is there any licensing issue if I use OODT file manager in Airavata?
>3. What is the preferred way of using file manager client to talk to the
