Do you mean that you imported one Item containing two Bitstreams, and DSpace created a separate Bundle of type ORIGINAL for each Bitstream of that single Item? Or that you imported two Items each containing one Bitstream and found two ORIGINAL Bundles, one for each Item? The former seems incorrect, the latter correct, if I understand the design. I believe that there should be 0 or 1 Bundle of any given type, per Item. So, for example, an Item submitted with no Bitstreams attached would have no ORIGINAL Bundle, while an Item submitted with any positive number of Bitstreams would have one ORIGINAL bundle. A second Item with Bitstreams would have one ORIGINAL bundle distinct from that of the first Item (the Bundle.ID value is unique). I find this remarkably difficult to describe in natural language. :-) -- Mark H.
