org.dlese.dpc.ndr.DleseAsUseCaseHelper
public class DleseAsUseCaseHelper extends Object
Just a few examples of fetching info from NDR. Approach:
  1. first get the MetadataProviderReader (which is the object type in the NDR from which collection information is obtained.
  2. then using the list of metadataHandles obtained from the mdp, get the item-level records (not a speedy operation)
