Subject Re: Apache Airavata-OODT Integration
Date Mon, 08 Jul 2013 07:09:32 GMT
Hi Chris,
     I have started looking at changing the current implementation to use
file Name instead of product id. As per the current PGETask wrapper
implementation, it takes two inputs (Product ID or file path at the remote
location. If filePath is used force staging should be set. But I am not
quite sure what it means by force staging). If I am to use the current
provisions in PGETaskWrapper, then remote file path (Not the file  name)
has to be given as input. I am not quite sure whether it is ideal to use
file path instead of file name. If filename to use as input, then
FilesStager needs to be customized to  retrieve product references from
file name. File manager client doesn't have a mechanism to retrieve product
by file name. But it has mechanism to retrieve product by product name. I
guess typically both are the same. One drawback of this approach is that it
doesn't support list of product names. The method getProductReferences
which returns list of products is based on back end implementation that is
based on product id, through actual input is product (Product with just
product name set is not possible to as input). Please let me know your
thoughts.

Best Regards,
Sanjaya
