Future development

Versioning of shared Albums

Following workflow would be possible:

  1. The user adds/removes pictures from the album. All his changes are only "pending" (not visible and changeable for other users of the album).
  2. The user has to "submit" his changes by entering a change description (e.g. in the notepad). When saving this comment, the changes will be visible and changeable for all users of the album.
  3. An event log will be provided, where only the submissions (together with the change description) are visible as single event logs.

--> Intellectual history will be provided (next to the technical one)

Problematic Scenarios:

  1. Two user are working parallel with the same album
    • User A is working on the album (his changes are in state pending). He added picture X to the album.
    • User B is also working on the album. For him picture X is marked as pending with following remark: "Added from user A".
    • When user A submitted his changes, picture X is not pending any more. That means, User B can see that picture X is added to the album and -if needed- can be removed by all users of the album.
