Class NullStreamIngestionCrosswalk

java.lang.Object
  org.dspace.content.crosswalk.NullStreamIngestionCrosswalk

All Implemented Interfaces:

StreamIngestionCrosswalk

public class NullStreamIngestionCrosswalk
extends Object
implements StreamIngestionCrosswalk

A crosswalk to ignore and dispose of the ingested material.

Specify this crosswalk in the mapping of e.g. METS metadata field types to crosswalks when you wish to ignore a redundant or unknown type of metadata. For example, when ingesting a DSpace AIP with an AIP ingester, it is best to ignore the rightsMD fields since they are already going to be ingested as member bitstreams anyway.
