6.5 Schema Mapping Policy

The Schema Mapping policy applies to both the Subscriber channel and to the Publisher channel. The purpose of the Schema Mapping policy is to map schema names, particularly attribute names and class names, between the Identity Vault namespace and the connected system namespace. The Schema Mapping policy is applied before the Output Transformation policy when Identity Manager submits or returns a document to the shim and after the Input Transformation policy when the driver submits or returns a document to the Identity Manager.Referring to the example of a new hire used earlier, the HR system uses First Name and the Identity Vault uses Given Name, when both refer to the same attribute. The Schema Mapping policy handles the change in names between the connected system's namespace and the Identity Vault's namespace. The Schema Mapping policy is bidirectional. It overlaps both channels. On the Publisher channel, the connected system's names are mapped to the Identity Vault. On the Subscriber channel, the Identity Vault names are mapped to the connected system.
