Hi Lucas, all;

and first off, thanks a bunch for your response and thoughts. Overally, well, though you didn't provide me with a real solution to my problem, at least you made me think more about what my actual use case is. This is good. :)

A few thoughts, so:

Instead, by using a single, centralized source of storage, that is
accessible via your local network (whether is uses physical cable
connections, or a Wi-Fi network setup). All your computers, fairly
independently of the different operating systems they may be running,
can access them using the same network file sharing scheme, CIFS/SMB.

Well. Yes. And no. Overally, of course, a central network storage, most likely a NAS, would make handling files and eventually database easier. But, in the end, and talking Linux-only machines: Isn't that, same as an external large USB drive, just a matter of being mounted anywhere in the file system? Mount points, volume labels and symlinks to the rescue, and it should easily be doable to have files in the same logical location on all machines even while living on USB storage.

But that's not actually my problem. On closer look: I see my use case not to be sharing files and data between local machines. My use case rather is syncing files and metadata between machines, and, in worst case, doing so incrementally, while some of these machines often to always operate offline. Given the netbook (vacation) or notebook+USB drive (business travel) use case: Most of these times, I try downloading and sorting images on a daily basis. In most of these situation, keeping a central storage is not an option as network connectivity either is too slow or too expensive or both. So, what I actually wanted to do is something like this:

1. Download and sort images, say, on the netbook. This would include things such as tagging, commenting and rating ("star") images. This is something I try doing day-by-day in order to somehow keep track of the vast load of images. The netbook and/or the USB drive by then would keep images of the current trip, sorted and tagged.

2. Back home, I would like to "somehow"(?) merge these images and its metadata into my existing image archive on my workstation machine. This mainly would include moving (not just copying) all the files off the netbook to the workstation into the image archive living there, plus importing the corresponding metadata to the workstations shotwell database.


Assuming the current shotwell ability to monitor an image folder and automatically import new additions, this would seem fairly straightforward, but so far I fail to see a way how to transfer metadata. Is there a way of storing metadata along with the images rather than in the database? Can one shotwell instance store comments, star rating, tags, titles, comments and all these things in JPEG EXIF _and_ another shotwell installment restore these information out of the EXIF while importing these images? Ultimately, I think that this might be the most straightforward way, assuming my use case, even though I am open to any suggestions outlining better ways. ;)

TIA and all the best,
Kristian
