PDF (Vector) at a glance
PDF (Vector)
PDF inherited its imaging model from PostScript, then became ISO-standardized, which let it displace older print-exchange conventions in many workflows that once depended on pure page-description languages or encapsulated graphics formats.
FITS at a glance
FITS
FITS became a durable scientific standard because observatories, spacecraft, and analysis tools needed a stable interchange format that outlived individual instruments and software stacks.
