Segment BluePrinting
To ensure BluePrinting integrity (future-proofing), when you first add an Address Book to a Child Publication in the BluePrint hierarchy, the root Publication in the BluePrint is “assigned” as the root. It becomes in effect an Audience Manager Publication.
When you add an Address Book to a Publication, the Audience Manager node becomes visible to users with rights to work with Audience Manager items. The Audience Manager node contains two subnodes: Address Books containing a list of Address Books assigned to a Publication, and Segments a root Folder containing subfolders in which Segments are organized. The only items that are BluePrinted in Audience Manager are the contents of the Segments Folder (Folders and Segments). Segments exist only as local items in the Publication they were created and shared items in Child Publications; you cannot create a “local copy” of a Segment.
