# Extending the Identity Store Provisioner contract

Identity Store Provisioners can be written with an option allowing administrators to add to the core attributes the plugin instance requires.

## About this task

Both the core and extended contract attributes you define must be mapped when you configure Write Users within an inbound provisioning connection.

|   | To keep your plugin flexible across multiple connections, assuming a one-to-one connection-to-identity store provider setup, you might want to hard code a set of core attributes for all connections to fulfill, and then extend attributes on as needed when a partner connection depends on additional attributes. |

|   |                                                                                        |
