Ingest Download Workflow Operation

ID: ingest-download

Description

With the IngestDownloadWorkflowOperationHandler it's possible to initially download external URI's from mediapackage elements and store them to the working file repository. The external element URI's are then rewritten to the stored working file repository URI.

In case of having external element URI's showing to a different Opencast working file repository, it's also possible to delete them after downloading it by activating the "delete-external" option. Additionally the "source-flavors" and "source-tags" option can be used to specify exactly, which external URI's should be downloaded.

This operation is originally implemented to get rid of remaining files on ingest working file repositories.
