Hi, Twisted is a framework for event driven applications. Typically client- server architectures can be implemented with Twisted. Existing servers and clients exist for a long list of protocols and communication devices including HTTP, SSH, and notably for my purpose, IMAP and UNIX sockets. It provides an event loop, and asynchronous Deferred objects which are similar to KJob objects. http://twistedmatrix.com/trac/ Akonadi is a cross platform PIM (personal information management) framework developed as part of the KDE4 platform. The goals of Akonadi include * Isolating user applications handing PIM data such as emails, contacts, notes etc from the protocols used to access or store that data (IMAP, POP, Maildir, Groupware, vcards, etc). * Provide a single point of storage (actually a cache) of PIM data accessible and manipulatable by any application written in any language on the target platform. http://pim.kde.org/akonadi/ Akonadi is designed as a client/server architecture. The server is written in Qt/C++, and we already have one client library for interfacing with the server written in C++ using the KDE platform. Notifications of changes to data are transmitted over D-Bus, and the actual data is transferred over a local socket (on Unix. On windows it's a named pipe). The protocol used for communication is IMAP with some non-standard extensions. And so the purpose emerges :). I have started an Akonadi client library written in python using twisted- imap with some extensions on top of it for Akonadi specific functionality. The code currently lives here: http://gitorious.org/python-twisted-akonadi There is the twisted-akonadi library a gtkAkonadi library containing some high level classes for PyGtk applications and a simple email reader and addressbook written in pygtk. Because Akonadi keeps everything in sync, you can change items in a KDE application, the gtk application, or the django application, and the other two will be instantly updated with the change. I've blogged about it twice already here: * http://steveire.wordpress.com/2009/10/09/holy-grail-no-thanks-weve- already-got-one/ * http://steveire.wordpress.com/2009/10/13/cross-platform-akonadi-video/ As you can see, this is only a proof of concept of the project. The aim is to create a library which feels pythonic and natural to use for twisted users. If you think I've started in the wrong way, or you have ideas for ways this API could be used, please let me know. I've just started with twisted, so I've probably not found some stuff which would make this task easier. Additionally, if you would like to contribute to the project, that would be very welcome. :) If you find the ideas here interesting and want to know more, the Akonadi developers are in #akonadi on Freenode and kde-pim at KDE.org, and I am already in #twisted. It isn't quite a twisted success story yet, but I think it has the potential to become one. All the best, Steve.
