I have searched for more information around my original post. Thanks to Johannes and Halgeirr for their replies.
As Halgeirr says, TIFF is the only real way to save lossless image files. As a scientist I have become very familiar with data integrity and images to the point where my work only allowed monochrome images which were made with narrow bandpass filters to select just a few wavelengths. You can not get such accuracy with anything that processes an image and provides sRGB colour. You probably can not get such accuracy with any consumer camera at all! As a normal photographer I do require exif-meta data as a way of putting information with my images. I tried to find a workaround to my problem. When I workup images on a Windows box the images can be picked up by any Linux software without problem. However, the reverse was not the case with the exception of Adobe software. Adobe are clearly sticking to their own tiff specification that any tiff file must be readable by any tiff based software. Whilst doing some other work I thought about Image Magick. Sure enough, "convert *.tiff -endian LSB *.tiff" will churn, very slowly, through a directory of DarkTable sixteen bit tiff files and make them Windows software readable. Unfortunately this process destroys most of the exif-meta data. Also the MM tab at the start of the file remains and is not changed to II. (Tiff files can be loaded in any text editor to see this.) This means that IM converted files have to be stored separately in a different archive. I am going to guess that the real problem is Microsoft yet again. Yet again, it would be great if Linux could handle this image situation. My Pentax dng or pef files take on a life and quality that I have never seen before using Darktable and Amaze. What's more is that this can be done from a batch that contains all sorts of exposure settings. The auto settings work very well.
