Setting Up Key Cross-Referencing in the Source Integration Server
The source resource sends a notification document to the source Integration Server when a data change occurs in the source resource. This section describes how to define the logic for the source Integration Server to:
Receive the notification document,
Use notification document to build the canonical document, and
Publish the canonical document.
You create a service to build and publish the canonical document. The logic to build the canonical document uses built-in services for key cross‑referencing, which are described in
Built-In Services for Key
Cross-Referencing. In this chapter, the service that builds the canonical document is referred to as a notification service.
You should implement key cross‑referencing for both one-way and n-way synchronizations.
The following diagram highlights the part of data synchronization that this section addresses.
