We need new frameworks for data transformation provenance in complex systems modeling. Open source R&D from the cadCAD community and venture science investments (time/knowledge/R&D) from BlockScience on CATs (see article https://medium.com/block-science/the-cats-out-of-the-bag-introducing-content-addressable-transformers-7483e61e3844) aim to provide that by combining CATs & cadCAD - a powerful toolkit which is and can be applied in DeSci.
