Hi Ross, XBaya uses a workflow tracking schema [1] for all metadata exchanges for workflow monitoring. The scheme is designed right from the onset to meet both the provenance and workflow orchestration goals. If the question is does Airavata also bundles provenance tools, then the answer is no. But if the question is literally 'reasonably competent handling of provenance metadata' the answer is a clear yes. XBaya is designed right from the onset with provenance goals. XBaya was part of the Provenance Challenge [2] and features in first and second challenges [3], but once the group moved to OPM and later to W3C provenance, the Xbaya code did not retain compatibility. But Prof. Beth Plale and team at IU lead the Karma provenance efforts which is available from sourceforge [4]. If the follow on question is what it takes to integrate XBaya with provenance tools like Karma and make it OPM or W3C Provenance complaint (which I personally consider is too lean to do any meaningful provenance) is very minimal, almost at the scale of a GSoC project. I will be happy to mentor/guide any such efforts.
