Scenarios

Implemented (1.0)

• Create collection: The user wants to create a collection with a corresponding metadata profile, upload pictures to this collection, assign/edit the metadata values of the pictures within the collection. During this process, the collection and the pictures should only be visible (and searchable) to the creator.
• Share collection: The user wants to work together with colleagues on a collection: the colleagues should be able to upload pictures to the collection, assign/edit metadata values to the images within the collection (but not change the metadata profile or the descriptive metadata of the collection). During this process, the collection and the pictures should only be visible (and searchable) to the creator and his contributors.
• Publish collection: When the creator (and optional his contributors) thinks that the collection is on a level that should be visible for other users, he published it. That means that now the collection and all pictures are visible and searchable for all user.

Not implemented

• Updating of a released collection (incl. versioning):

1. Upload of new pictures
   • When the user uploads new pictures for a collection, he first want to upload them in a protected environment (where only he or optionally his colleagues can see them, where he can take his time to assign metadata values to each picture.
   • When he is finished with this work, he wants to publish the new version of the collection, so that now all pictures within the collection are visible to all user.
2. Changes in the metadata values of a collection
   • When the user wants to change the metadata values of the pictures within a collection, that is normally more than one edit. So he wants to have a protected environment where he (and optionally his colleagues) can do the changes.
   • When he is finished with this work, he wants to publish the new version of the collection, so that all changes within the collection are visible to all user.

During the time when somebody is updating a collection, which is not released jet, all other users should always see the old version as last published version.

• Citing a collection: When a user cites a collection, he want to cite exactly the current state of the collection. Therefore each version of a collection has to be marked persistent. So that when a user follows the cited URL, he always got the cited collection, and not the latest version of the collection (Permlink scenario: the user wants to cite the current state of the collection --> he can create a version with a citable URL). But of course a hint that a newer version of the collection exists, should be displayed.
