Class ItemTag

java.lang.Object
  javax.servlet.jsp.tagext.TagSupport
      org.dspace.app.webui.jsptag.ItemTag

All Implemented Interfaces:

Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.Tag

public class ItemTag
extends javax.servlet.jsp.tagext.TagSupport

JSP tag for displaying an item.

The fields that are displayed can be configured in dspace.cfg using the webui.itemdisplay.(style) property. The form is

 
 <schema prefix>.<element>[.<qualifier>|.*][(date)|(link)], ...
 
 

For example:

 
 dc.title = Dublin Core element 'title' (unqualified) dc.title.alternative =
 DC element 'title', qualifier 'alternative' dc.title.* = All fields with
 Dublin Core element 'title' (any or no qualifier) dc.identifier.uri(link) =
 DC identifier.uri, render as a link dc.date.issued(date) = DC date.issued,
 render as a date
 
 

If an item has no value for a particular field, it won't be displayed. The name of the field for display will be drawn from the current UI dictionary, using the key:

 
 "metadata.<style.>.<field>"
 
 e.g. "metadata.thesis.dc.title" "metadata.thesis.dc.contributor.*"
 "metadata.thesis.dc.date.issued"
 
 
 if this key is not found will be used the more general one
 
 "metadata.<field>"
 
 e.g. "metadata.dc.title" "metadata.dc.contributor.*"
 "metadata.dc.date.issued"
 
 

You need to specify which strategy use for select the style for an item.

 
 plugin.single.org.dspace.app.webui.util.StyleSelection = \
                      org.dspace.app.webui.util.CollectionStyleSelection
                      #org.dspace.app.webui.util.MetadataStyleSelection                                            
 
 

With the Collection strategy you can also specify which collections use which views.

 
 webui.itemdisplay.<style>.collections = <collection handle>, ...
 
 

FIXME: This should be more database-driven

 
 webui.itemdisplay.thesis.collections = 123456789/24, 123456789/35
 
 

With the Metadata strategy you MUST specify which metadata use as name of the style.

 
 webui.itemdisplay.metadata-style = schema.element[.qualifier|.*]
 
 e.g. "dc.type"
