Abstract
A Provenance-Aware Storage System (PASS) is a storage system
that automatically collects and maintains provenance or
lineage, the complete history or ancestry of an item.
We discuss the advantages of treating provenance as
meta-data collected and maintained by the storage system, rather than
as manual annotations stored in
a separately administered database.
We describe a PASS implementation, discussing the
challenges it presents, performance cost it incurs, and the new functionality
it enables.
We show that with reasonable overhead, we can provide useful
functionality
not available in today's file systems or provenance management systems.
