org.dspace.content.crosswalk.DisseminationCrosswalk
Dissemination Crosswalk plugin -- translate DSpace native metadata into an external XML format.
This interface describes a plugin that produces metadata in an XML-based format from the state of a DSpace object. Note that the object may be an Item, Bitstream, Community, or Collection, although most implementations only work on one type of object. @author Larry Stone @version $Revision: 3761 $
