Ibis: A Provenance Manager for MultiLayer Systems

End-to-end data processing environments are often comprised of several independently-developed (sub-)systems, e.g. for engineering, organizational or historical reasons. Unfortunately this situation harms usability. For one thing, systems created independently tend to have disparate capabilities in terms of what metadata is retained and how it can be queried. If something goes wrong it can be very difficult to trace execution histories across the various sub-systems. One solution is to ship each sub-system's metadata to a central metadata manager that integrates it and offers a powerful and uniform query interface.
