Okay, to follow up I did some research and experimentation (with much
appreciated help from CNRI) on getting multiple (or at least two) handle
prefixes to resolve in DSpace and got it to work. What is needed is that 1)
the handles from all desired prefixes exist on the DSpace postgres table
"handle", 2) in [dspace]/handle-server/config.dct has all the desired
prefixes listed in sections "server admins", "replication admins" and
"backup admins" (this seems to be how DSpace "homes" its handle prefixes for
the handle server), and 3) have CNRI create/update all the desired prefixes
using the same sitebndl.zip package created by
[dspace]/bin/make-handle-config.
The comment and the dspace.cfg key connnected to it (which is, by the way,
missing from the DSpace 1.5.2 config file) found on the DSpace
HandlePlugin.java seems to have little or no effect on whether resolving
multiple handles actually works.
This was still an experiment using non-production handles and the real acid
test on whether it works is still ahead of us - so the usual caveats apply.
Cheers,
