I'm at ESTEC (ESA's European Space Research and Technology Centre) in the Netherlands this week for my first #PLATO science working team meeting as community scientist. One interesting discussion has been on astronomical file formats (honestly)... Future NASA missions look like they might move from #fits to #ASDF, while other astronomical surveys have started using #HDF5. But it's tough to try to predict exactly where the community will be in 5-10 years time. Input welcome!

@ExoHugh I really hate getting an undocumented or poorly documented file. It is very challenging to parse it's contents. Having the human readable header metadata at beginning of fits/asdf files is a godsend for simply cat/less a file to figure out what's in it.

@CuriousTerran Agree 100% - my main experience of HDF5 has been digging through file trees searching for where the data I want is hidden... But a large part of that is (lack of) familiarity & external documentation, so maybe HDF5 could work just fine as a standardised mission output?
