62  * "Null" ingestion crosswalk
63  * <p>
64  * Use this crosswalk to ignore a metadata record on ingest. It was
65  * intended to be used with a package importer such as the METS
66  * packager, which may receive metadata records of types for which it
67  * hasn't got a crosswalk. The safest thing to do with these is ignore
68  * them. To do that, use the plugin configuration to map the name
69  * of the metadata type to this plugin (or within the METS ingester,
70  * use its metadata-name remapping configuration).
71  * <pre>
72  * # ignore LOM metadata when it comes up:
73  * plugin.named.org.dspace.content.crosswalk.SubmissionCrosswalk = \
74  * org.dspace.content.crosswalk.NullIngestionCrosswalk = NULL, LOM
75  * </pre>
