When the user decides to upload, the changes in wikimedia_commons tags (#11) should be added to a changeset and then be uploaded to OSM. The app should make sure that linked images or categories do already exist.
I have to make sure that the altered objects are first downloaded (directly, not Overpass) from the API to have the newest version. Then I can upload the changeset either directly over the API or use osmapi.
