Customizing the "Tag Cloud" facet

[Alex B]

Dear Tim,

how to implement Customizing the "Tag Cloud" facet?

as I understood in https://wiki.lyrasis.org/display/DSDOC7x/Discovery#Discovery-Customizingthe%22TagCloud%22facet

in discovery.xml  -  under the line

<!-- Set TagCloud configuration per discovery configuration -->
<property name="tagCloudFacetConfiguration" ref="defaultTagCloudFacetConfiguration"/>

insert

<!--TagCloud configuration bean for homepage discovery configuration-->
<bean id="homepageTagCloudFacetConfiguration" class="org.dspace.discovery.configuration.TagCloudFacetConfiguration">
        <!-- Actual configuration of the tagcloud (colors, sorting, etc.) -->
        <property name="tagCloudConfiguration" ref="tagCloudConfiguration"/>
        <!-- List of tagclouds to appear, one for every search filter, one after the other -->
        <property name="tagCloudFacets">
            <list>
                <ref bean="searchFilterSubject" />
            </list>
        </property>
</bean>

and 

<bean id="tagCloudConfiguration" class="org.dspace.discovery.configuration.TagCloudConfiguration">
              <!-- Should display the score of each tag next to it? Default: false -->
              <property name="displayScore" value="true"/>
              <!-- Should display the tag as center aligned in the page or left aligned? Possible values: true | false. Default: true  -->
              <property name="shouldCenter" value="true"/>
              <!-- How many tags will be shown. Value -1 means all of them. Default: -1 -->
              <property name="totalTags" value="-1"/>            
              <!-- The letter case of the tags.
                      Possible values: Case.LOWER | Case.UPPER | Case.CAPITALIZATION | Case.PRESERVE_CASE | Case.CASE_SENSITIVE
                      Default: Case.PRESERVE_CASE -->
              <property name="cloudCase" value="Case.PRESERVE_CASE"/>
              <!-- If the 3 CSS classes of the tag cloud should be independent of score (random=yes) or based on the score. Possible values: true | false . Default: true-->
              <property name="randomColors" value="true"/>
              <!-- The font size (in em) for the tag with the lowest score. Possible values: any decimal. Default: 1.1 -->
              <property name="fontFrom" value="1.1"/>
              <!-- The font size (in em) for the tag with the lowest score. Possible values: any decimal. Default: 3.2 -->
              <property name="fontTo" value="3.2"/>
              <!-- The score that tags with lower than that will not appear in the rag cloud. Possible values: any integer from 1 to infinity. Default: 0 -->
              <property name="cuttingLevel" value="0"/>
              <!-- The distance (in px) between the tags. Default: 5 -->
              <property name="marginRight" value="5"/>
              <!-- The ordering of the tags (based either on the name or the score of the tag)
                      Possible values: Tag.NameComparatorAsc | Tag.NameComparatorDesc | Tag.ScoreComparatorAsc | Tag.ScoreComparatorDesc
                      Default: Tag.NameComparatorAsc  -->
              <property name="ordering" value="Tag.NameComparatorAsc"/>  
    </bean>

I get errors:

Maybe I misunderstood the instructions?

[DSpace Technical Support]

Hi Alex,

As noted by the docs you linked to, the "Tag Cloud" is not supported in DSpace 7.x (or 8.x).  So, those docs are invalid at this time, until we are able to return support to DSpace for this feature.
