Creating a Nextcloud App/Plugin
I don't know if this is a good idea because it would add a lot of work, and it could easily be break with new Nextcloud releases. But here is my idea.
Actually, parsing EXIF data and creating metadata for new pictures take a lot of time. Because of that, it seems difficult to port the app on iOS devices. But, if we do all this work on the server during the cron job, we could easily enhance the global app performance. We could create a simple app that does minimal tasks in order to avoid app incompatibility with newer Nextcloud releases, and which works like an api that gives the mobile app all the needed informations about medias.
This can really enhance the app, but it has to be optionnal because I think not everyone has access to the server. Again, this would represent some work and this is probably not worth it, but it's an idea.
What do you think about it?
