All At the end of the call today we discussed provenance as a key kind of metadata we would like to access through the metadata part of an LSID (or ARK or whatever). I said I would post round the call for the Provenance Challenge that is ongoing...See below. As I do this I wonder if we should have an Identity Challenge. We produce a couple of data sets that simulate real data sets; we produce some application scenarios that reflect changes in the databases, accessing the data, moving the dataset etc and then we try out LSID, ARK and whatever identity scheme you fancy. Then we would have some concrete comparison of capability, cost of take-on, various metadata vs data scenarios, versioning schemes etc.... just a thought. Carole (now on vacation with the rest of Europe...) Call for Participation: First Provenance Challenge 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 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. Participants of the challenge are presented with an example experiment workflow design, using publicly available tools, and data. They are free to implement this workflow as they prefer, e.g. using their own workflow enactment system, as batch scripts etc. There are then a series of queries about the provenance of the experiment results, for which each participant shows how they would answer the queries using their system. The challenge will conclude with a workshop held at Global Grid Forum 18 (GGF/OGF-18) in Washington DC in September, where we will discuss the results of the challenge and compare approaches. Details of GGF-18 are available at http://www.ggf.org/GGF18 Full details on the challenge, and how to participate, are available at: http://twiki.ipaw.info Any questions about the challenge are welcome. Please send them to sm@ecs.soton.ac.uk. Thanks, Simon Miles, Luc Moreau, Mike Wilde, Ian Foster, Yong Zhao Universities of Southampton and Chicago >
