Though, to be clear -- the replicate code is *not* hooked up to DSpace's SWORD ingestion process yet.
So, if we wanted to ingest bags via SWORD (which sounds like a good idea to me), I believe there's still one piece missing: * a SWORDIngester class which calls the replicate code to ingest a bag received via SWORD into DSpace. (This would be similar to how there's a SWORDMETSIngester which forwards METS packages on to the DSpace METS PackageIngester) - Tim On 7/27/2011 5:05 PM, Richard Rodgers wrote: > BTW, the replicate code does all this - serializes and deserializes bags to > DSpace objects > > Richard > On Jul 27, 2011, at 5:56 PM, Stuart Lewis wrote: > >> Hi Hardy, >> >> SWORD is completely agnostic about what packages it transports, however out >> the box, DSpace does not know how to ingest bags via SWORD.
