Yes, as Robin and Richard point out. You can create your own
crosswalks/packagers. Hypothetically one could try to enable the AIP
Packager through SWORD. You could then expose the AIP via interface and
write tools against the full set of metadata. However it sounds like Ying
is attempting something that is a one time transfer of all content from
DSpace to Fedora/Islandora. I'd recommend focusing on getting everything
out of DSpace into a file system, then massaging it into the state needed
for import into Fedora. Using SWORD itself for this is not necessarily of
great importance. Though, in the future, enabling such round-tripping for
other migration cases would be of benefit to the community. This is where
the mapping Ying ultimately does may be of interest.
A tangent... I was just thinking about this over my morning coffee...
SWORDv2 does describe an atomic process for putting and getting individual
media resources in its specification.
http://sword-app.svn.sourceforge.net/viewvc/sword-app/spec/tags/sword-2.0/SWORDProfile.html?revision=377#protocoloperations_retrievingcontent_feed
This could represent the basic API layer for a DSpace storage service to be
bound to any SWORDv2 (possibly any APP service) as its store. I this
regard, Richards point about getting SWORDv2 services for Fedora worked out
would be a great benefit to the whole DSpace/Fedora initiative.
Cheers,
Mark
