AIP store● AIS Packager stores AIP into PDS● ID Manager updates IDs adding PDS ID● PDS triggers Storlets according to rules

Resource status update● The resource is shown as “preserved” in the Active System

Resource Restore Workflow● Active System can send request to PoF Middleware (REST API)● Scheduler creates a new job, initial message sent● Collector retrieves DIP, containing original resource (or new one after

transformation by PDS), which is returned to Active System
