The condition Tagbox Item Unassigned checks if a specific tagbox item ("a tag") is unassigned in a specific field e.g. Check if the tag "Twitter" is unassigned in the field "SocialMediaPlatforms" on Layer "CopyrightUsages" to then remove this image from Twitter. The Business Rule may check if the tag "Dealer Portal Europe" was unassigned to then e.g. remove the view permission for European dealers.
