Special Issue: The First Provenance Challenge

TLDR

The first Provenance Challenge was established to provide a forum for the community to assess the capabilities of different provenance systems and the expressiveness of their provenance representations. The challenge defined a functional MRI workflow that participants had to simulate or run to generate provenance representations and answer a set of queries, and the paper presents this workflow, the queries, and summarizes participant contributions. Participants either simulated or executed the defined fMRI workflow to produce provenance data, which was then queried according to the challenge specifications. Sixteen teams responded to the challenge and submitted their provenance representations. © 2007 John Wiley & Sons, Ltd.

Abstract

Abstract The first Provenance Challenge was set up in order to provide a forum for the community to understand the capabilities of different provenance systems and the expressiveness of their provenance representations. To this end, a functional magnetic resonance imaging workflow was defined, which participants had to either simulate or run in order to produce some provenance representation, from which a set of identified queries had to be implemented and executed. Sixteen teams responded to the challenge, and submitted their inputs. In this paper, we present the challenge workflow and queries, and summarize the participants' contributions.
