The Advanced Scientific Data Format (ASDF, not to be confused with the Adaptable Seismic Data Format) is a "proposed" replacement for Flexible Image Transport System and other astronomy data (namely, image) formats. Like FITS and similar formats (HDF, etc.), it is meant to store both large amounts of data and metadata describing it in the same file. ASDF uses YAML to store this metadata. "Blocks" are compressed with either Gzip or Bzip.[1]
