• First Provenance Challenge: The first Provenance Challenge was set up in order to provide a forum for the community to help 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.

More information about the challenge workflow and queries can be obtained at http://twiki.ipaw.info/bin/view/Challenge

The papers presented at the First Provenance Challenge appear in a special issue of Concurrency and Computation: Practice and Experience. The references can be found at:
