OSISoft has had PI to PI to perform data roll up functionality on the continuous data portion of the database for years. It typically involves a tag name mapping exercise to be performed to allow site based PI systems to feed a regional or enterprise based PI system, as well as the care and feeding as new "tags of interest" are added to the PI universe.
Has anyone tried to do the same with batch data? How was the regionalized / globalized context added to the batch context? How was the cross site query information handled?
Any thoughts are welcome.
