CowboyRobot writes: Lucian Carata and colleagues at the University of Cambridge describe the importance of knowing where data comes from and what processes may have altered it. In "A Primer on Provenance", they describe how sometimes the transformations applied to data are not directly controlled by or even known to developers, and information about a result is lost when no provenance is recorded, making it harder to assess quality or reproducibility. Computing is becoming pervasive, and the need for guarantees about it being dependable will only aggravate those problems; treating provenance as a first-class citizen in data processing represents a possible solution.
