About predefined navigation attributes

AVEVA OMI includes a set of predefined Navigation attributes. Read-only navigation attributes identify neighboring navigation items of the selected item by name or fully qualified path location. Read-write attributes can be used in action scripts and animations to define actions that can change the current navigation item in a running ViewApp. When the context of the ViewApp shifts from the current navigation item to a destination navigation item, the associated content of the destination item appears in the ViewApp.

A typical runtime navigation workflow based on Navigation attributes is for the user to select a graphic element shown in a ViewApp that includes an action script or animation containing Navigation attributes. The script or animation creates a navigation action based on the attributes to shift the view context to another navigation item in the ViewApp's navigation model.
