Thanks Spirio for your interest. You are in right direction and only problem i
am able to see is setting the type of data(["type"]=> int(0)) while creating
experiment. Following is a sample code from a PHP example. If you set the type
to URI on experiment creation then airavata should treat it as a file.
/* Experiment input and output data. */
$input = new DataObjectType();
$input->key = "input";
$input->value = $input_data;
$input->type = DataType::URI;
As Marlon and Suresh said, a handout can help us understand your use case
better and point you to right examples.
Thanks
