kdepimlibs Splitting Epic


The KDE PIM community has outlined the following plan for splitting kdepimlibs into Frameworks libraries

  • Wait for the kdelibs split to be completed and the preview release to be made
  • A frameworks branch to be created in kdepimlibs and Qt5 / KF5 basic porting to be performed here mostly by the Frameworks team (old frameworks branch to be reviewed and deleted)
  • Once work is started here no more style fixes to be applied to Master
  • Code relying on qt3support and deprecated libraries will be removed as part of the porting
  • Once porting is completed then kdepimlibs will be spilt into separate frameworks
  • Once split the maintainers of each framework will take over work to make any API and code changes required
  • PIM Frameworks will be released as and when they are ready, we do not need to release them all at the same time
  • PIM Frameworks will be prioritised depending on usage, i.e. libraries needed by KDE Workspaces and Kolab should be released first
  • kdepim-runtime will be split between PIM Framework and kdepim


See the other Frameworks pages for the KDE Frameworks Policies, the kdelibs Split Policies and the Definition of Done .

The kdepimlibs specific policies are:

  • Modules that use qt3support are to be removed
  • Deprecated API is allowed to be removed
  • Source compatibility requirements are relaxed due to fewer clients, but major rewrites are discouraged. Instead port the old library and create a separate new library (e.g. KHolidays and QHolidays).
  • Most libraries will aim for Tier 2, but some may be able to target Tier 1.
  • The initial KF5 port may rely on kde4support to enable the port to be performed by non-experts, but no Framework released may rely on kde4support so the maintainer must remove all usage. In particular all KDateTime, KTimeZone and KLocale usage must be removed and the Qt replacements throughly tested for regressions and behaviour changes.


The following libraries are known to be used outside of KDE PIM and so may be a higher priority in porting.



  • Grep'ed for each folder name


  • kde-workspace/libs/plasmaclock/
    • KHolidays
  • kde-workspace/plasma/generic/dataengines/akonadi/
    • Akonadi
    • KMime
    • KABC
    • Microblog
    • KPimUtils (linked but not included?)
  • kde-workspace/plasma/generic/dataengines/calendar/
    • Akonadi
    • KCalCore
    • KCalUtils
    • KHolidays
  • kde-workspace/plasma/generic/dataengines/rss/
    • Syndication

Note: It is recommended that the Akonadi DataEngine be reworked/renamed as EMailEngine, ToDoEngine, etc, as this is client developer facing API and so the implementation name should be abstracted/hidden from them, i.e. as is done with the CalendarEngine.
