Principles of Provenance (Dagstuhl Seminar 12091)

Authors: James Cheney, Anthony Finkelstein, Bertram Ludaescher, and Stijn Vansummeren

Published in: Dagstuhl Reports, Volume 2, Issue 2 (2012)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 12091 ``Principles of Provenance''. The term ``provenance'' refers to information about the origin, context, derivation, ownership or history of some artifact. In both art and science, provenance information is crucial for establishing the value of a real-world artifact, guaranteeing for example that the artifact is an original work produced by an important artist, or that a stated scientific conclusion is reproducible. Since it is much easier to copy or alter digital information than it is to copy or alter real-world artifacts, the need for tracking and management of provenance information to testify the value and correctness of digital information has been firmly established in the last few years. As a result, provenance tracking and management has been studied in many settings, ranging from databases, scientific workflows, business process modeling, and security to social networking and the Semantic Web, but with relatively few interaction between these areas. This Dagstuhl seminar has focused on bringing together researchers from the above and other areas to identify the commonalities and differences of dealing with provenance; improve the mutual understanding of these communities; and identify main areas for further foundational provenance research.

Scientific Workflows: Catalyzing the Grid ⇌ Semantic Web Reaction

Authors: Bertram Ludaescher

Published in: Dagstuhl Seminar Proceedings, Volume 5271, Semantic Grid: The Convergence of Technologies (2005)

Abstract
Scientific workflows allow scientists to automate repetitive data management, analysis, and visualization tasks, and to document the provenance of analysis results. Scientific workflows are composed of interlinked computational components (sometimes called actors), and the datasets that are consumed and produced by those components. Scientific workflow systems are problem-solving environments to design, reuse, share, execute, monitor, and archive scientific workflows. As such, they are the primary tool that end user scientists use when interacting with the emerging e-Science cyberinfrastucture. Scientific workflow systems can often benefit from both, Grid and Semantic Web capabilities. Thus, scientific workflows can bring together these otherwise loosely connected technologies and "catalyze the reaction" between them.
