Just to give you a bit of background on my request I work in banking and specifically validating models. We generate a lot of paperwork for the tests we perform on the models for the regulators. Being the results of the test reproducible is a pretty neat feature that's why having a way to store the analyzed data in a standard way would be good, if the data is too big and for some situations at least having a way to check that the data has not change could be enough, that's why the hash. Finally, this is a problem being tackled now in my area and I have seen 4 or 5 big companies demoing solutions to solve the problem. Thanks and good luck!
