Resource status overview (this should list all resources existing in KDE3 or already under development for Akonadi):

Resource Retrieve Collections Retrieve Items Change Collections Change Items Configuration Notes
iCal yes (4) yes (1) (2) no yes (5) yes does not yet watch for file changes
vCard yes (4) yes (1) (2) no ? yes does not yet watch for file changes
maildir yes (1) (4) yes (1) (2) ? ? yes
mbox no no no no no not started yet, code exists in KMail
IMAP yes (1) (4)? yes (1) (2) no no no code exists in kio_imap4 and Mailody, support for extensions: quota, ACL, annotations missing, what about Kolab and Scalix?
POP3 no no no no no not started yet,code exists in kio_pop3
NNTP yes (4) yes (2) n/a n/a yes Needs support for local collection names and collection hierarchy
Local Bookmarks ? ? ? ? (3) Code in akonadi/resources
OpenChange ? ? ? ? ? Code in akonadi/resources
Facebook ? ? ? ? ? Code in playground/pim
del.icio.us ? ? ? yes no Code in playground/pim
KABC no yes no yes yes
KCal no yes no yes yes

(1) only full sync supported currently, need optimization (2) does not yet honor cache policy (3) still relies on QSettings for configuration and/or doesn't provide configuration over D-Bus (4) does not yet provide correct access control settings (5) only adding new items, not changing existing ones

Akonadi Braindump

Ideas/notes etc. on various open issues in Akonadi.

Akonadi Standard Actions

Idea: Have something like KStandardAction for Akonadi that not only includes the representation of the action but also its state management and the actual operations. Like libakonadi that should be splitted into a generic, type-independent part and be extensible for type-specific actions. This will enable code sharing among many applications and guarantee consistent actions everywhere.

State management: watch selection models of a collection and/or item model.

Use KXMLGUI for context menus in standard views to allow easy extensibility with custom actions.

Generic actions:

  • new collection
  • new virtual collection
  • delete collection
  • copy collection
  • cut collection
  • paste collection
  • synchronize collection
  • show collection
  • delete item(s)
  • copy item(s)
  • cut item(s)
  • paste item(s)
  • paste native data
  • tag item(s)
  • comment item
  • rate item(s)

The list is definitely long enough to make this worthwhile.

Collection Model / Collection View

Ideas/missing features/bugs of the collection model/view:

  • Enable/disable status columns
  • Show status after the name (see KMail)
  • Size column
  • Save/restore layout
  • Custom collection icons (see KMail, also needed for resource defined special folders (eg. Inbox)
  • Status tooltips (see KMail in 3.5.9)
  • Quick search
  • Favorite folder view as proxy model on top of the normal collection model (FlatCollectionProxyModel might be helpful for there)

Compatibility

Notes on how to keep long-term protocol, source and binary compatibility.

  • Detect server version in Akonadi::Session, might be useful in case of protocol extensions/changes
  • What about database server version updates?
  • Versioning or any other kind of serialization format meta data, we'll need that in case of changes in serialization formats (see eg. Robert's compression patch where this is needed)
  • We currently use 32 bit ids, probably hard to change later on, is that enough?

KMail Breakdown Plan

The current plan is to put some parts of KMail into a stand-alone library, independent of KMail. This increases code reuse (for example, the message composer could be shared with Mailody) and makes the code a lot easier to maintain and to port to Akonadi.
