      <FormatDescription>Common Data Format is a library and toolkit that was developed by the National Space Science Data Center (NSSDC) at NASA, used for the storage and processing of multi-dimensional datasets. The ‘dotCDF’ file as described in the specification refers specifically to the filetype with extension .cdf. The dotCDF file may be a standalone file containing everything it needs, or it may have companion ‘variable’ files with the extension .vX, where X represents an incrementing numeric value, e.g. .v0, .v1 etc.
This entry covers versions 2.0-2.5. Version 2.6 onwards introduced optional compression, and earlier versions require further research.</FormatDescription>

There are additional elements in the CDF Descriptor Record that may be used to strengthen the signature is required, and potentially to further divide into separate sub-versions if required.
