Sorry for cross-posting: Call For Scenarios: The Fourth and Last Provenance Challenge (PC4) This is a call to the community for scenarios for the Fourth Provenance Challenge. This is to prepare for the PC4 scoping workshop to be held at IPAW'10. Scenarios are due May 15. If you have an interesting scenario for the community to work on together, this is a great opportunity to contribute. - More information on PC4 can be found at http://twiki.ipaw.info/bin/view/Challenge/FourthProvenanceChallenge - A scenario template and the submission page are at: http://twiki.ipaw.info/bin/view/Challenge/FourthProvenanceChallengeCFSP Motivation for PC4: The FirstProvenanceChallenge (PC1) was designed to compare expressiveness of provenance systems. It was followed by the SecondProvenanceChallenge (PC2) to exchange provenance information between systems. The consensus that followed led to a proposal for the Open Provenance Model (OPM), a data model for provenance. OPM was tested during the ThirdProvenanceChallenge (PC3). Following the success of this challenge, an open-source governance approach was adopted for OPM, which led to revision OPM v1.1. Three considerations are motivating the launch of a novel challenge: * So far, the Provenance Challenge activity has had a strong focus on scientific workflows. While we certainly wish to keep the involvement of the scientific workflow community, we would like to demonstrate the broader applicability of provenance technology. For instance, it would be desirable to consider scenarios that involve users, where computations take place on the desktop and in the cloud, where various forms of artifacts are manipulated, e.g. data sets, files, documents, databases, and where artifacts are published and downloaded from the Web. * Furthermore, there is no point capturing provenance if we do not make use of it. It would therefore be desirable to make use of provenance, to demonstrate functionality that would have been impossible to implement without provenance. * Broader scenarios in which provenance is captured, and better exploitation of provenance to demonstrate functionality make use converge towards an end to end scenario, in which multiple technologies are involved, and really justifies the need for an interoperable solution. Hence, the purpose of the Fourth and Last Provenance Challenge is to apply the Open Provenance Model to a broad end-to-end scenario, and demonstrate novel functionality that can only be achieved by the presence of an an interoperable solution for provenance. This challenge, the last one in this successful series, will be its natural conclusion since it will exploit OPM in an end-to-end scenario, following steps understanding provenance (PC1), posing the problem of provenance inter-operability (PC2), and testing the OPM solution (PC3). Relationship to W3C Incubator on Provenance: In parallel, we note the activities of the W3C Incubator on Provenance, which has collected use cases, derived requirements, and is in the process of beginning a technology roadmap. The Incubator and PC4 are complementary activities, which should cross-fertilize each other. Incubator's use cases and requirements can influence the PC4 scenario, whereas PC4 practical experience with OPM can inform the incubator. Timetable: April 15: call for scenario proposals May 15: review of proposed scenarios and discussion June 1: selection of a scenario June 15: expressions of interest June 17, 2010: scoping workshop co-located with IPAW'10 at Troy NY, USA. A goal of the scoping workshop is to the scope of PC4 and its dates. Thanks for your contributions, Paul Groth and Luc Moreau
