John, Down here in Texas we also face this challenge to create a federated repository among all institutional repositories across the state. Up until now we've been doing a manual federation process which includes dspace imports and exports plus some scripts that work on those exports. This has been a huge pain to work with, but it's bought us time to develop something better. We have been working on a patch which we expect to make public sometime next week. Right now we're working out a few library dependency issues with maven. The patch requires database changes so I don't expect it for 1.5.2, but hopefully soon their after.
This patch will add: Part A: The ability for a DSpace collection to be harvested from another repository via OAI-PMH. When you look at the collection editing screen in either Manakin or the JSPUI there will be another tab for collection source that allows a curator to set up harvesting for a collection. It can be done either as a one-time thing just to move a collection or you can have it periodically harvest the collection. Further more you'll be able to select from three types of harvests 1) just metadata (plain old OAI-PMH), 2) metadata + bitstreams (via ORE), 3) metadata + links to bitstreams in their source repository (i.e. we get the ORE document and store that in DSpace but don't grab the bitstreams individualy). Part B: The ability for DSpace to serve up ORE documents via OAI-PHM.
