Provenance Origin and Authenticity of Results Provenance of computational processes Recorded documentation of processes as they take place With this documentation, we can determine: the origin of electronic data and the compliance of the process that led to the data Definition of provenance The Provenance of some information is the history of its creation Related Terms “Data Lineage” is another word for Provenance Provenance is NOT “Logging” Folie 23 Korea e-Science AHM 2008 > Andreas Schreiber > Data and Knowledge Management in Aerospace Engineering > 08.09.2008
  21. 21. Provenance Example Queries Given some data item, what was the simulation case? Given some parameter, in what simulation(s) has it been used? What data has been recorded in a simulation with a specific parameter? What simulations have been run using a given model (aircraft design)? Given two/more simulations with the same setup, what is the result and the difference in provenance? What have been the initial conditions for this simulation? What were the termination criteria? How often has the workflow been executed? What specific algorithm/version has been used in computations? What were the hosts participating in the simulation run?
