Profile Metadata is where you can manage all of your Interaction Types and Identifier Types for a specific project.
Interaction Type
Interaction Type manages all of the different interactions, the channels in which they occur, and the individual engagement score for that Interaction Type. Once an interaction type is defined, you can select it in a dropdown menu via the Save Interaction Node
Identifier Type
Xponent Identity Manager now includes a way for you to manage your customer profiles called Identifier Type. It represents how you want to identify the customer. For example, you can create an Identifier Type called "email," and this could contain one or more email addresses.
For Example:
[ "myworkemail@domain1.com", "mypersonalemail@domain2.com" ]
When you first create a project, the only Identifier Type that will be in existence is the Xponent ID (KWID).
