Hello,
I ran into a data-file which is a "CDF V2 Document, No summary info",
according to /usr/bin/file. To my surprise there seems to be nothing
in Debian which supports this format. The canonical CDF library
appears to live at http://cdf.gsfc.nasa.gov/ and has a license (
http://cdf.gsfc.nasa.gov/html/CDF_copyright.html ) which in its
entirety reads:

There has been some queries on the freeness of CDF before on debian-legal (see
http://lists.debian.org/debian-legal/1999/06/msg00052.html and
http://lists.debian.org/debian-legal/2002/08/msg00099.html ) but as
far as I know, CDF has never been uploaded to Debian.
The conclusion I draw from the threads above is that the license above
is DFSG-free. Are there any other opinions?
Best,
Teemu
