We're trying to havest the metadata from our IR, SMARTech (running DSpace
1.7.2) to a metadata-only repository running DSpace 1.8.2, using the OAI
harvester. For the most part, it's going well -- but we have a lot of
items in SMARTech mapped to more than one collection. When the harvester
hits one of these mapped items, having already ingested its doppelganger,
it throws an error:
2012-03-28 12:37:37,526 ERROR org.dspace.harvest.OAIHarvester @ Harvesting
error occured while processing an OAI record: Handle collision: attempted
to re-assign handle '1853/10302' to an incoming harvested item 'oai:
smartech.gatech.edu:1853/10302'
This makes sense, since the handle is indeed already in use -- but the
harvester exits on the error, and nothing else in the collection is
harvested. I'm assuming that anybody else who attempts to harvest metadata
from SMARTech is getting the same behavior. Has anybody else run into
this? Unless I'm missing something, it seems like this would make it
impossible to do a full harvest on a site using mapped items.
Thanks,
