Tags are one of the most powerful features of Adobe Experience Manager (AEM), using tags content authors and asset managers can create secondary taxonomy associations between content. The challenge with many AEM installations is that tag taxonomies tend to grow over time, especially if ad-hoc tags are enabled. AEM's Tag Administration console allows Taxonomy Managers to delete, merge and move tags, however, before making changes, you really understand how a tag is used. You can view references, but this is only available at the individual tag level. Recently, I built a new Managed Controlled Process to create a report of the tags and their references.
