The Advanced Scientific Data Format (ASDF): Why you should use it
STScI has developed a new data format for use with JWST and the Nancy Grace Roman Telescope that addresses some of the constraints and issues that the FITS format has engendered. This talk will briefly outline the motivations for developing this format and describe the structure and features of the format, highlighting the advantages over FITS, particularly with regard to data organization and WCS capabilities.
