There are currently a few ways I can think of to work on the same project on multiple devices, but it is a bit embarrassing to discuss them, because they are clearly hacks, so please keep in mind that officially, Tropy does not support collaborative features yet (but we’re looking to improve that).
What is already possible is moving a project from one device to another. If you understand that process, you’ll see that there are few options to simultaneously work on the project from both devices. But first off, to move a project (for example, because you’re upgrading to a new computer), you would:
- Copy the project file and the photos to the new device.
- If the absolute path of the photos is the same on the new device as it was on the old device, that’s it: if you open the project, Tropy should be able to find all the photos and generate all the thumbnails (visible in the project view).
- If the paths are different, you’d have to tell Tropy where to find the files (see here).
Now, depending on your use case there are different options:
If you can set up your photos in a way to make them accessible on both devices using the same absolute path (e.g., using sym-links or by actually using the same paths) then you should be able to just use the same project file on both devices. However, I’d be careful not work on the project on both devices at the same time (because there no syncronization features yet, the two instances of Tropy are likely conflict with each other).
If you can not set up your photos in such a way (or if you don’t want to copy all the photos to both devices) you could still set up one device to work only on the metadata; you could also copy the thumbnails from one device to the other, which would make it possible to view the entire project on the second device (but you would not see the photos in the image viewer when switching to the item view). Tropy stores thumbnails in your ‘use data’ folder, e.g., ~/.config/tropy/cache
on Linux.
