Thanks, Tim, for taking a shot at it. Sorry for being too vague. The
requirements are pretty loose.
In this case, I have Community/Collection owners wanting to export content to
National Library of Medicine for indexing. For now at least, they'll need to
export the complete contents of a new collection each time. So, selecting the
content is pretty straightforward whether I use the AIP or OAI.
The metadata has to follow NLM's schema which is why I assume an XSLT crosswalk
is best.
The bitstreams need to be bundled up with, and referenced locally by, the
metadata.
Downloading to a specific location would be ideal, but exporting to the DSpace
server filesystem is fine; I can get it to them from there.
Yes, I think the AIP B&R is what I was referring to. It's just a little unclear
in the sysadmin documentation what the relationship is between the METS and AIP
packagers.
Given that's what I wanted, how would I specify a crosswalk for the AIP feature
to transform METS to NLM? Or is that even possible without writing a custom
packager?
And if Graham or anyone else is using DSpace to get stuff to NLM or other
indexers then I would love to hear from you.

Hi Jason,
I'm not sure I fully follow your use case, but a few things you may wish
to look at (if you haven't already):
* If you are looking at exporting METS + bitstreams, have you taken a
look at the AIP Backup & Restore feature (which generates "AIPs" that
are just zipped up METS files + bitstreams):
https://wiki.duraspace.org/display/DSDOC/AIP+Backup+and+Restore
More about the AIP format here:
https://wiki.duraspace.org/display/DSDOC/DSpace+AIP+Format
* If you are interested in hooking up Curation Tasks to
Packagers/Disseminators, that is possible. In fact, Richard Rodgers & I
are working on a 1.8.0 "add-on" called the Replication Suite, which
brings AIP export/import to Curation Tasks:
https://wiki.duraspace.org/display/DSPACE/ReplicationTaskSuite
More details in my slides from OR11 on using Replication Suite to
backup/restore to/from DuraCloud:
http://www.slideshare.net/tdonohue/dspace-duracloud-integrations
I'm not sure if either of these will help your use case or not, but both
are examples of using Packagers (along with crosswalks) to export METS +
bitstreams and enable that via Curation Tasks.
Perhaps if you described your use case a bit more? Is what you are
building an Administrator tool? End user tool? Is it a specific METS
format/profile you need, or specific Metadata schemas? When they
"export" are they actually needing to download it to a specific
location, or just export to the filesystem on the server where DSpace is
running? (the latter is how the Replication Suite works, unless you
connect it to DuraCloud or point it at a mounted drive)

Doing More with Less: The Next Generation Virtual Desktop
What are the key obstacles that have prevented many mid-market businesses
from deploying virtual desktops? How do next-generation virtual desktops
provide companies an easier-to-deploy, easier-to-manage and more affordable
virtual desktop model.http://www.accelacomm.com/jaw/sfnl/114/51426474/
