Kia ora! I've updated the hdf.desktop file.In addition I created an icon from the hdf5.pdf in http://www.hdfgroup.org/ftp/HDF5/contrib/hdf5-logo/hdf5.tar.gz in a rush. It is probably better to take the hdf group logo, which appears in the HDF window title.
For further hints on menu integration, see http://www.debian.org/doc/packaging-manuals/menu-policy/
