Re: #31

Yes, I agree, and I was going to get into metadata, but felt that my comment was already too long :-) So, is there a good way to do this with metadata? Maybe you'd tag the variant files something like:

VersionOfFileName: img1234.jpg
VersionOfUID: 0xF00BA8
VersionOfImageHash: 0x123456 (likely to be overkill)
ActiveVersionAsOf: 2008-08-06 13:42

Here the VersionOf tags all refer to the original image, the idea being that even if some files are renamed or removed we still have a chance to figure out the relationships. The "current" file to show would be the one with the most recent ActiveVersionAsOf tag. (Reverting to the original while keeping the variants, as F-Spot lets you do, would be a special case though, since we may not want to touch the original file at all?)

Or would one need something else or more sophisticated? I don't know; I am just trying to raise this for discussion by more knowledgeable people...
