Hello, I created a first version of a neutral format for multi-dimensional data (https://nbviewer.org/github/loco-philippe/ntv-numpy/blob/main/example/exampl... ) and I made available a first version of a package (https://github.com/loco-philippe/ntv-numpy/blob/main/README.md) with: - a reversible (lossless round-trip) Xarray interface, - a reversible scipp interface - a reversible astropy.NDData interface - a reversible JSON interface The previous Notebook shows that we can, thanks to this neutral format, share any dataset with any tool. I will integrate in a second version the existing structure for tabular data (https://github.com/loco-philippe/ntv-pandas/blob/main/README.md) and the associated reversible interface . If you have examples of other tools to integrate or validation datasets, I'm interested! Have a nice day
