Perhaps tiff-like.

"Providing a detailed and concise description of the content of raw 
files is highly problematic. There is no single raw format; formats can 
be similar or radically different. Different manufacturers use their own 
proprietary and typically undocumented formats, which are collectively 
known as raw format. Often they also change the format from one camera 
model to the next. Several major camera manufacturers, including Nikon, 
Canon and Sony, encrypt portions of the file in an attempt to prevent 
third-party tools from accessing them.[2]"

A real mess.

'.raw' is used (among others) by Panasonic and Leica. Not clear if .raw 
is the same for both.
