Suggestion for experimental data schemas

I’m looking for suggestions for a standard schema to save metadata about experimental data characterized by AFM, XRD, Raman, Transport, etc… I think Nomad has done some work in this area. Are there other efforts I should know about?

For AFM data I would like to follow a standard format instead of something ad hoc like,
“Trace”: “Retrace”,
“Width”: 1.0E-6,
“Length”: 1.0E-6,
“Name”: “Height Sensor”,
“PointsPerLine”: 512,
“Unit”: “nm”,
“Roughness”: 1.2765437556792394,
“Rmax”: 25.400080738520483

Thanks for any pointers you can give.
