removal from former site
The moment an object leaves its former site and begins its journey toward a new location.
An object is removed from its former site at the moment when its journey to a new site begins. This event marks the start of a process ending with the object's relocation to a new site.
The event records departure on the relocation journey. Preparing the destination alone does not mean that the object has left its former site.
Relocation to a new site records arrival at the destination. Departure and arrival are separate milestones even when the movement takes only a short time.
