UC_FAC_AM_01 Create album

User roles to be checked for album creation. See http://zim01.gwdg.de:8080/browse/AS-525 for more infos. --Natasa 10:47, 27 August 2008 (UTC)

DEV ToDo

• extend create album with create notepad, and add notepad as member of the album

SVM ToDo

• check metadata of notepad (item can not be created without a metadata record, would publication metadata suffice? or copying the metadata from the album? --Natasa 11:48, 16 January 2009 (UTC)

UC_FAC_AM_02 Add picture to album

Possibility to add one picture to more than one single album in one step

1. GUI: Is not possible with an intuitive GUI (Data quality! No undo available!) The functionality of seeing which pictures are already in an album (in the browsing view) will get lost. Maybe as admininstrative feature --Unfried 13:59, 8 September 2008 (UTC)
2. DEV: Can be technically provided. Tricky part is to automatically tell user in which albums (with status different from "released", "withdrawn" he has privileges for adding) the picture was already added (toDO: check with FIZ on querying the semantic store) --Natasa 15:46, 25 August 2008 (UTC)

Conclusion:

As the requirement of adding one picture to several albums within one step can not be supported by the GUI, we decided to delete it from the requirements. --Kristina 07:49, 12 September 2008 (UTC)

Based on the conclusions above and related to R3.5 spec

All comments below from --Natasa 11:55, 16 January 2009 (UTC)

1. see no inclusion of this use case in View Album Details use case, as when we are viewing album details we can only remove pictures from album (because we only look at existing pictures) but not add new pictures to this album
2. precondition shall include additionally "or the user has at least one shared album"
3. the current spec of this use case assumes that the user selects an album each time she would like to add an image to an album
4. current R2/R3 implementation assumes an album is preselected as an active album, and only in this case the adding of images to an album is possible
   1. if the latter is the case, then the use case shall be extended with the pre-condition that one album is selected, and the flow of events should exclude the step of selecting of an album

UC_FAC_AM_03 Remove picture from album

Dev Input

• precondition shall be "the user is the owner or is sharing the selected album"

UC_FAC_AM_05 Delete album

Remarks for GUI implementation:

• If only one album was selected we can move to detail page, where shared users are visible and invoke the message. If more than one album is selected the sytem displays the message only plus confirmation. --Unfried 15:10, 8 January 2009 (UTC)

  • i find quite complicated to allow for deletion of an album if there are shared users to this album, because if each shared user automatically gets his/her own notepad (which I find even more problematic).
  • would propose the following stages with album management and album picture manipulation
    • A. Album is created and has status pending, only album creator can see it, and it is not allowed to share other users
    • B. Album is shared, and gets status "submitted", in this case album can be shared with other users
    • C. If album is shared, it can be deleted only if there are no shared users to this album and it is put back in status "pending"
  • I would especially suggest to remove the batch deletion of albums as a possibility, or to allow it only for "pending" albums, concerning the proposal above.

UC_FAC_AM_06 Release album

DevInput

• Comments from --Natasa 12:54, 16 January 2009 (UTC)
  • in case workflow proposed in Talk:Faces_Album_Management#UC_FAC_AM_05_Delete_album is accepted then release of an album can be done:
    • When album is in status pending, and is not shared (in this case automatically gets status submitted and afterwards released)
    • When album is in status submitted, and is shared (in this case one transition to status released is made) (for this purpose, the precondition needs to be changed accordingly).
  • Question: shared NotePad can still be album member and does not have to be released ever. The same is the case with evtl. private notepads. Can these be edited after an album is released?

UC_FAC_AM_07 Withdraw album

DevInput

• Comments from --Natasa 13:02, 16 January 2009 (UTC)
  • Question: what is happening with the notepads during the Album withdrawal? Shall they all be really deleted?
    • proposal: delete them all just before an album is withdrawn in the core service (i.e. after user confirmed the withdrawal)

UC_FAC_AM_09 Share album

Usage of user groups for the sharing of an album

Instead of sharing an album with several users, the possibility of creating an user group can be used

1. Create a user group
   1. A user (who has the corresponding privileges) creates a user group by providing e-mail addresses of possible participants.
   2. The system invites the possible participants via e-mail.
   3. The possible participants confirm their participation in the user group by following a link provided by the e-mail.
2. Sharing of an album with a user group
   1. Visibility
      • User group and their participants must be visible to the owner of an album
      • Each user can only see the user groups and their participants he is part of
      • During invitation: is interesting to know which users are also invited to the user group (independently if they already have confirmed their participation or not) --> not possible
   2. One user group will be selected to share the album.
   3. Users will get a notification but do not have to confirm the sharing.
   4. When a user does not want to share the album he has to leave the user group. When the group is sharing other albums, too, he will unshare this albums, too.

Conclusion:

Not really interesting for FACES. User groups will only be discussed when the institute requires them. --Kristina 13:12, 22 December 2008 (UTC)

How to add a shared user:

Two possibilities were discussed:

1. Via User Name
2. Via e-Mail Address

Conclusion:

Via user name is not possible because the user name is not known by the system when using a handle system --> via e-mail address will be used (was decided in an internal meeting on 11.12.08; participants: Natasa, Rike, Bastien, Rupert, Denise, Markus M., Kristina)

  • See the proposal at Talk:Faces_Album_Management#UC_FAC_AM_05_Delete_album
    • if this proposal is accepted, then the flow and this use case need to be changed.
      • we need "submit for sharing" album use case that would submit the album and will automatically create a shared notepad
      • for clarity rename this use case to "add shared users to an album" (and exclude automatic creation of a shared notepad)

• • To clarify a bit the steps 2, 3 specified in the UC:
    • 2. The system displays the share album entry mask. The user enters for each shared user an valid e-mail address and confirms his input.
      • I assume this will be like an email send form, where user can add as many email addresses as they wish, delimited with ",".

In addition, user may add in the message body some free text, in addition to "User X invited you for sharing of this album" and some more explanations on how to ask for a user account or log-in to the system.

• • • 3. The system saves each e-mail as inactive shared users to the album and sends each of them a notification. Further on, a shared note pad (item) in the state pending will automatically created by the system and related to the album. The use case ends successfully.
      • After confirmation of the email, the system sends this email to all addresses in the email.
        • Afterwards users continue with UC_FAC_AM_10 Confirm shared user

UC_FAC_AM_12 Copy album content

Remarks for GUI implementation:

• GUI might be different here because multiselect is necessary. --Unfried 15:33, 8 January 2009 (UTC)
