redo the search in OAI-PMH as I originally advised ;^)

go look it up! I tried to convince them that OAI plus lucene was enough to get very solid structured metadata / clever data offa all 9 collection sets (we already did it for 45 dbs at the NHM). Downside of course is you need a repository and this was a peer to peer concept. Opensearch I'm still a lot less convinced about - and the current implementation only buffs the paintwork of the real collections... Not very long tail. and inability to AND is a FAIL imo.
