Abstract
Current provenance collection systems typically gather metadata on remote hosts and submit it to a central server. We describe middleware for managing distributed provenance metadata, where each host maintains an authoritative local repository of the provenance metadata gathered on it. The approach provides several advantages — the system can scale to handle the large amounts of metadata generated when auditing occurs at fine granularity; users retain control over their provenance records; and the middleware transparently queries remote provenance stores to reconstruct distributed lineage.
