32 Related Work Provenance Visualization Provenance Map Orbiter[Seltzer et al. TaPP 11] captures large provenance graphs and provides navigation mechanism. Navigation model for scientific provenance[anand et al. WORKS 09]. DDG takes advantage of Little-JIL s hierarchical structure Undo Mechanism [Leeman TPLS 86] proposed a formal approach to undo operations. Selective undo model [Berlage TCHI 94] provides the user with the ability to undo an arbitrary operation in history. Our approach takes into account both control flow and data flow Undo in WFMSs Kepler tolerates faults by providing check-pointing and forward recovery [Mouallem et al. SSDBM 10]. Self-healing Kepler (periodically constructing checkpoints) [Hary et al. HPDC 10]. Our approach is complementary and allows undoing work and trying a different strategy when the results are unsatisfactory

33 Contributions and Future Work Sensor Calibration Raw Data Calibrated Data Quality Control Quality Controlled Data Model Based Gap-filling Gap-filled Data Contributions: Undo tasks while remembering old artifacts and consequences Modify a data-processing step without losing the history Automatically redo set-aside tasks that are consistent with the modification Our approach is implemented as a command-line tool. Future Work: User interface for browsing and querying the DDG Detect conflicts in redo operations
