You can use design/change-time policies to make changes to assets when certain events occur. Setting instance-level permissions on an asset is an example of an update you might make using a policy. Other kinds of changes you might make include classifying an asset, setting a specified attribute when an asset completes a series of tests and changing an asset's lifecycle state.

CentraSite provides built-in actions that you can use to perform many kinds of updates to assets. You can also create custom actions to modify assets.
