Class XSLTDisseminationCrosswalk

java.lang.Object
  org.dspace.core.SelfNamedPlugin
      org.dspace.content.crosswalk.XSLTCrosswalk
          org.dspace.content.crosswalk.XSLTDisseminationCrosswalk

All Implemented Interfaces:

DisseminationCrosswalk

public class XSLTDisseminationCrosswalk
extends XSLTCrosswalk
implements DisseminationCrosswalk

Configurable XSLT-driven dissemination Crosswalk

See the XSLTCrosswalk superclass for details on configuration.

Additional Configuration of Dissemination crosswalk:

The disseminator also needs to be configured with an XML Namespace (including prefix and URI) and an XML Schema for output format. This is configured on additional properties in the DSpace Configuration, i.e.:

   crosswalk.dissemination.PluginName.namespace.Prefix = namespace-URI
   crosswalk.dissemination.PluginName.schemaLocation = schemaLocation value
   crosswalk.dissemination.PluginName.preferList = boolean (default is false)
 

For example:

   crosswalk.dissemination.qdc.namespace.dc = http://purl.org/dc/elements/1.1/
   crosswalk.dissemination.qdc.namespace.dcterms = http://purl.org/dc/terms/
   crosswalk.dissemination.qdc.schemaLocation = \
      http://purl.org/dc/elements/1.1/ http://dublincore.org/schemas/xmls/qdc/2003/04/02/qualifieddc.xsd
   crosswalk.dissemination.qdc.preferList = true
