DataFrames: Which formats (if any) support saving of metadata

Just as a side note, TableMetaDataTools.jl has utilities to save metadata as toml files and then re-load them and attach them to a data frame. So in theory you could save a .csv and a .toml together and load them both.

Oh, that’s good to know.

Do you know of a file format that is able to store the metadata in the same file as the table?
