Package org.dspace.importer.external.metadatamapping.contributor

Class MultipleMetadataContributor<T>

java.lang.Object
org.dspace.importer.external.metadatamapping.contributor.MultipleMetadataContributor<T>
All Implemented Interfaces:
MetadataContributor<T>
public class MultipleMetadataContributor<T> extends Object implements MetadataContributor<T>
This Contributor is helpful to avoid the limit of the Live Import Framework. In Live Import, one dc schema/element/qualifier could be associate with one and only one MetadataContributor, because the map they're saved in use dc entity as key. In fact, in this implementation we use the MetadataFieldConfig present in this MultipleMetadataContributor contributor, but the data (values of the dc metadatum) will be loaded using any of the contributor defined in the List metadatumContributors, by iterating over them.
