Center node: "Provenance in databases"
  Abstract: The provenance of data has recently been recognized as central tothe trust one places in data. It is also important to annotation, todata integration and to probabilistic databases. Three workshops havebeen held on the topic, and it has been the focus of several researchprojects and prototype systems. This tutorial will attempt to providean overview of research in provenance in databases with a focus onrecent database research and technology in this area. This tutorialis aimed at a general database research audience and at people whowork with scientific data.
