This is a classic “tag cloud” "tag cloud" facet in a DSpace repository.

The new JSPUI-only tag cloud facet feature is disabled by default. In order to enable it, you will need to set up the corresponding processor that the PluginManager will load to actually perform the tag cloud query on the relevant pages. This is configured in the dspace.cfg configuration file using the following properties:
- plugin.sequence.org.dspace.plugin.CommunityHomeProcessor
- plugin.sequence.org.dspace.plugin.CollectionHomeProcessor
- plugin.sequence.org.dspace.plugin.SiteHomeProcessor
The tag cloud has been declared there for you but it is commented out.
