Reusable cross-calibration workflows

At the talk presented on International Astrophysical Consortium of High Energy Calibration (IACHEC) meeting I describe a concept and a prototype of  reusable cross-calibration workflows for inter-calibration of astrophysical experimentation. I suggest to define and allow a dynamically composed unit tests for data and data analysis, establishing a platform for automated comparison and validation of scientific data and data analysis methods. These functions are among the core activities of ground segments (and especially Data Centers)  of astrophysical experiments and observatories.
