I think I'll know better once I see some examples, Sanjaya,
so looking forward to them, please proceed.

Cheers,

Subject: Configuration management for Airavata integration with OODT file
Manager server

>Hi,
>Airavata integration with FileManager to stage file prior to excute
>workflow task is based on the class PGETaskInstance of the OODT CAS-PGE
>module. PGETaskInstance takes both dynamic metadata and workflow
>configuration as an input and it combines them to create PgeMetaData
>object. Main purpose of the Airavata integration with OODT is to stage
>input files and ingest output data back to file manager server and
>Metadata
>catalog. Since workflow configuration is managed by Airavata itself, it is
>possible to configure only dynamic Metadata which should configure items
>such as QUERY_CLIENT_TRANSFER_SERVICE_FACTORY and
>QUERY_FILE_MANAGER_URL(Then static Metadata is represented by Metadata
>object which doesn't have any properties. Presence of both dynamic and
>static Metadata is mandatory in PgeMetadata implementation). Please let me
>know if you see any drawback with this approach of allowing to configure
>only dynamic Metadata for Airavata integration with FileManagerServer to
>stage files and making static Metadata empty.
>I would like to see some sample configuration files for dynamic and static
>Metadata.
