Koha OAI server requests directly MySQL database in order to get all
biblio records biblionumbers. So for now, without changing Koha OAI
engine, we would have to limit queries to MySQL queries. We could
imagine something like:

  ALL: SELECT biblionumber FROM biblio;
  PER: SELECT biblionumber FROM biblioitems WHERE itemtype='PER';

We could very easily define a ALL set returning the whole catalog as
it's already done.

Koha OAI Server doesn't have also incremental harvesting capabilities.
