Hello folks,
in our case (Univ of Helsinki) we want to keep the originals in MH so
that we can transcode them thru future workflows when necessary (for
example: atm we use flash but I wish we'll be able to convert the vids
to h.264 soon). Moreover, we want to make sure that MH's metadata is as
accurate as possible and that there would be no orphan media files on
the disk. These hopes in mind we also want to give each mediapackage a
distinct lifetime, which in our case is 12 months. After 12 months we
ask (a shell script) the teacher/professor to extend the lifetime of a
mediapackage - if necessary. If the mediapackage's owner doesn't extend
the lifetime, the media file will first be hidden and then - some months
later - deleted permanently and removed from the disk.
In my opinion it is _crucial_ that MH keeps track of all the metadata
and that the media files are handled by MH. Only this way a cleanup
process is able to remove both the unnecessary files and folders and
also the metadata from the database. It would be a nightmare if the
files and the db would be out of sync.

We already have a bit of an issue with disk space in MH, so we would
end up turning this back on right away. We archive outside of the
system atm.
To me it's no big deal to have it on or off by default, so 0 from me,

As part of our default workflow, we enforce the "cleanup" operation,
which is removing all files referenced by a single media package from
the file system in order to save space and prevent disks from filling
up. So far for the pros of making this the default behavior.
On the downside, mediapackages get added to the various indexes in
Matterhorn (workflow, episode, search) that can't be used for further
(or repeated) processing since they are basically invalid, having
pointers to files and catalogs that don't exist anymore. This will be
true until we have a working archive in place which unfortunately
does note seem doable until 1.5.
In order to make sure people make an active choice to have their
original media and catalogs removed, I #propose to comment out that
operation and add documentation right into the workflow that explains
what happens if a user choses to enable it. But if they don't they
are still by default maintaining a working installation with valid
media packages.
I am especially looking for feedback from adopters.
