Personally I need to store RAWs. I don't have any use for a DAM (Digital Asset Management) system that doesn't let me store RAWs (or at least import to DNG with most, if not 1:1, of the information intact).
I'm mulling over implementing it myself, as a self-host solution. Probably aim for ingesting RAWs to DNGs, and have the possibility of losslessly doing some edit/transforms (store the operations outside the DNG files) -- along with export/view/cache as jpeg and jpeg 2000 for web browsing etc.
Somewhat related, I came across dpbestflow[1] again, just now -- and I see they've added some information about (archive) file formats since I stopped by last. I wasn't aware jpeg 2000 had a lossless mode (nor that it generally compressed better than other lossless formats). Nor was I aware a number of archive institutions have standardized their DAM/Archiving on lossless jpeg 2000.
I suppose one would still need DNG/RAW if one want to keep the door open for being able to "re-develop from negative" on archived photos (jfr. archiving/keeping old negatives, which would be the equivalent for traditional photography).
Anyway, the site[1] might be of interest for those that find this thread interesting.
