Package org.dlese.dpc.schemedit.ndr

Class CollectionImporter

java.lang.Object
org.dlese.dpc.schemedit.ndr.CollectionImporter
public class CollectionImporter extends Object
Extracts data from a Collection Metadata object and loads it into the NCS data structures to create a collection, and then creates item-level metadata from MetadataObjects in the NDR (transforming to native format if possible).

ISSUE: can we import arbitrary collections, or is it REQUIRED that NCS-level information (e.g., format) is present.
