Last weekend was not only the time for the KMail Hacking Days but
also for the second Akonadi·
Hacking Meeting in Berlin, Germany. 7 KDE-PIM developers came together for 2 days at the KDAB offices in Berlin's Kreuzberg district and
continued to improve Akonadi, the personal information data storage for KDE 4. Meeting the other developers in real life and discussing issues face to face
always helps to find new solutions and implement crucial features in a short
period of time.
The first big step was to make the setup of Akonadi as easy as possible.
Now you just have to start the 'akonadi_control' application and all other
components of Akonadi, including the external MySQL process, are started
automatically so you can begin to read and write data from/to the storage
To be able to test the functionality effectively the application
'akonadiconsole' (which is supposed to be a test application only) was extended
to support displaying type specific information. Only a few lines of code later
it was able to show contacts stored in Akonadi
Under the hood the code of Akonadi was cleaned up and the API of libakonadi
improved for easier extension in the future.
Also the roadmap of the project was refined and the next steps to take clarified,
so on the server side the API of the resources (that are plugins which
communicate between the Akonadi storage and external sources
e.g. groupware servers) will be simplified to allow 3rd party developers to
create new resources by just reimplementing 3 virtual methods.·
On the client side the next steps will include writing models
for all kind of PIM data (e.g. mails, contacts, events, todos) which
fetch their data from Akonadi. This task is covered by a Google Summer of Code
Another step will be to write components like editors and viewers
which work standalone with the Akonadi storage and provide features like
live-update on changes and conflict resolution, new developers for these tasks are always welcome :)
