A.3 Channels

The flow of data between the Identity Vault and a connected system has two directions named Publisher and Subscriber. These directions are named from the point of view of the connected system:

  • The Subscriber channel is the channel in which data flows from the Identity Vault to the application via the shim. The applications subscribe to data from the Identity Vault.

  • The Publisher channel is the channel in which data flows from the application to the Identity Vault. The applications publish data to the Identity Vault.

There are cases in which policy might cause data to conceptually flow backward in a channel. This is referred to as channel write-back.
