Session 1: Team inputs 1: Each team will summarise their involvment in the challenge, present the provenance traces produced by theirs system, and how they addressed provenance queries. Provenance is a critical concept in scientific workflows, since it allows scientists to understand the origin of their results, to repeat their experiments, and to validate the processes that were used to derive data products. During a discussion on provenance standardization at the GGF-sponsored International Provenance and Annotation Workshop (IPAW'06, www.ipaw.info), the community decided that it needs to understand the different representations used for provenance, its common aspects, and the reasons for its differences. As a result, the community agreed that a "Provenance Challenge" should be set to compare and understand existing approaches. The draft of the challenge, currently available from twiki.ipaw.info, is to be finalized by the community by June 15th: participating teams will complete the challenge by September 10th. The proposed GGF-18 event is a workshop to analyze how the competing teams have addressed the challenge, and to draw conclusions on common and differing aspects on provenance.
