Many of the properties contain lists which use references to point to the configuration elements. This way a certain configuration type can be used in multiple discovery configurations so there is no need to duplicate these.

SidebarFacet Customization

This section explains the properties of an individual SidebarFacet, like SidebarFacetAuthor, SidebarFacetSubject and SidebarFacetDateIssued from the default configuration. In order to create custom SidebarFacets, you can either modify specific properties of those that already exist or create a totally new one from scratch.

Here's what the SidebarFacetAuthor looks like:

<bean id="sidebarFacetAuthor" class="org.dspace.discovery.configuration.SidebarFacetConfiguration">
        <property name="indexFieldName" value="author"/>
        <property name="metadataFields">
            <list>
                <value>dc.contributor.author</value>
                <value>dc.creator</value>
            </list>
        </property>
        <property name="facetLimit" value="10"/>
        <property name="sortOrder" value="COUNT"/>
        <property name="type" value="text"/>
    </bean>

The id & class attributes are mandatory for this type of bean. The properties that it contains are discussed below.

• indexFieldName (Required): A unique sidebarfacet field name, the metadata will be indexed in SOLR under this field name.
• metadataFields (Required): A list of the metadata fields that need to be included in the facet.
• facetLimit (optional): The maximum number of values to be shown. This property is optional, if none is specified 10 will be used. When a type of date is given, this property will not be used since dates are automatically grouped together.
• sortOrder (optional): The sort order for the sidebar facets, it can either be COUNT or VALUE. If none is given the COUNT value is used as a default.
  • COUNT Facets will be sorted by the amount of times they appear in the repository
  • VALUE Facets will be sorted alphanumeric
• type (optional): the type of the sidebar facet it can either be date or text, if none is defined text will be used.
  • text: The facets will be treated as is
  • date: Only the year will be identified from the values and stored in the SOLR index. These years are automatically grouped together and offered as a drill-down browse.
