Can you tell us more? how do you express a "ragged_array" in netcdf 4?
Variable length user-defined types, maybe?
To answer my own questions, I found this:
http://www.unidata.ucar.edu/software/netcdf/workshops/2010/netcdf4/VarLens.html
so yes, essentially ragged arrays are built-in to netcdf4.
So if we want to go the netcdf4 route, that would be a bit easier.
Although I do note this:
"""
Access to a variable-length value is atomic
Length and values written or read together
Can't know length until value is read
"""
That's a pity -- sometimes it is nice to know how big something is
before you read it, but probably not a big deal in the common use cases.
