Provenance Integration Requires Reconciliation

Free registration required

Executive Summary

While there has been a great deal of research on provenance systems, there has been little discussion about challenges that arise when making different provenance systems interoperate. In fact, most of the literature focuses on provenance systems in isolation and does not discuss interoperability - what it means, its requirements, and how to achieve it. The authors designed the Provenance-Aware Storage System to be a general purpose substrate on top of which it would be "Easy" to add other provenance-aware systems in a way that would provide "Seamless integration" for the provenance captured at each level.
