Hi Nathan:
Not sure I have one lying around, but the bag contents are pretty simple:
All bags have a payload file 'object.properties' that contains the object type
(Item, collection, community),
the handle, and the parent handle. They also have a payload file called
'metadata.xml' that has whatever metadata the object has:
(for communities, that would be the name, short description, copyright text,
etc, for items, it would be the DC (or other) metadata).
For items, under the 'data' directory in the bag are subdirectories for each
DSpace bundle (name = bundle name),
In these, there is a pair or files for each bitstream: the bitstream itself
(named by sequence number) and the bitstream metadata file.
Thus, for 2 bitstreams, directory contents would be:
1
1-metadata.xml
2
2-metdata.xml
I think the big question is what the preservation repository requires (beyond
bagit formatted packages). It could expect specifics, or not.
Hope this helps,
Richard R

We're running DSpace 1.8x and need to export collections as bags (per the Bagit
spec) to ingest into a preservation repository. From reading the Replication
Task Suite documentation, this should be possible. However, before we install
and configure RTS, I'd really like to see an example output bag. Would anyone
be willing to share?
Other options to get content into a bag is to export as SAF or AIP and use
scripts to convert into bags. If anyone has done this before, I would very much
appreciate learning more about your workflow.
Many thanks,
Nathan
