Bidirectional photo sync with a 3rd party app?

Workflow to manage photos would benefit from bidirectional sync features:

  • digital twin of selected iOS photos on Nextcloud share: we can then delete photos on iPhone and create new albums as compiled.
  • No need to delete photos manually on selected albums / unsorted.
  • iOS shared Albums to be supported Will shared photo albums be visible in iOS Client? to have access to everything
  • on mobile a lower resolution images support much smaller space, faster loading
  • seamless integration in backup flow

Limitations to manage

  • Space on iPhone
  • Space on Nextcloud

Preferred workflow in consideration

  1. Continuous backup of selectable objects: all photos unsorted and albums in original image quality - keep these

  2. on Nextcloud share: copy select best photos and tag them with (XMP) and target album keywords.

  3. export selected in lower resolution to save space on iPhone; structure to include albums.

  4. share with users

  5. sync / import this directory back with the iPhone as per point 1. For new albums created they have to be added to bi-dir sync list in the Nexcloud app.

As per discussion above the key for me is to select photos for bidirectional sync, like the timeline and/or selected albums.

Happy to hear about other solutions and workflows.
