The Telepathy framework is a DBus specification which provides a cross-desktop and cross-protocol abstraction layer for instant messaging, voice/video over IP and collaborative applications. See the Telepathy web site for more information about Telepathy itself.

This project is focused on integrating Telepathy with KDE. Our high-level aims are the following:

  • to provide a unified instant messaging and voice/video communication framework within KDE, which integrates throughout the desktop experience.
  • to provide collaborative features in applications which fit seemlessly into the KDE platform
  • to provide the infrastructure within KDE necessary to acheive the above two, using cross-desktop specifications and implementations wherever possible.


This section contains details of all the Telepathy-in-KDE infrastructure components, and their statuses.

Telepathy Integration Daemon

This is a small light-weight daemon that monitors the Telepathy Account Manager and keeps ensures that all Accounts are recorded in Nepomuk as NCO:Contact instances of "myself" and that they each have a Telepathy Contacts Akonadi Resource instance.

It could possibly be made into a KDED module, but I'm not sure if this is a good idea. Grundleborg


The bare bones are implemented, but the Nepomuk part is blocking on standardising the Ontologies for telepathy specific stuff and how to access the "myself" PIMO:Person through Nepomuk. The Akonadi part is blocking on getting the Telepathy Contacts Akonadi Resource below implemented.

Telepathy Contacts Akonadi Resource

This is an Akonadi Resource that synchronises the contacts of a Telepathy Account into Akonadi as vcards. The instances of this resource are managed by the telepathy-integration-daemon mentioned above.


Partially implemented. Requires some Telepathy CM's to implement the org.freedesktop.Telepathy.Connection.Interface.ContactInfo.DRAFT interface to complete it, since we shouldn't try and support legacy CM's which don't support that interface.

The code can be found in the KDE svn playground at the following URL:

Account Management KCM


  • One single UI that any application can load for add/edit/delete Telepathy Accounts
  • Creates a dynamic UI on-the-fly using Connection Manager parameters, but this should be used only when a specific UI plugin for that CM isn't installed.
  • Create specialised UI plugins for the popular CM's (e.g. gabble) since dynamic UI will be pretty crap usability-wise.


Some code is there in svn, but it's pretty much just experimental shell-files. So feel free to ignore existing code to implement this :) Grundleborg

Telepathy Enabled Applications


  • QtDBus doesn't have peer-to-peer DBus implemented properly - the classes are just non-functional stubs. This stops us from implementing D-tubes in KDE/Qt based Telepathy applications. Upstream bug is private in Qt Software's tracker and this is unlikely to get fixed by Qt Software, so if anyone feels like implementing it and then merging it upstream into Qt, that would be really fantastic.
  • Telepathy-Mission-Control still requires you to use both the channel dispatcher part of it and the Account Manager. For KDE, we need to be able to use only the Channel Dispatcher from Mission-Control and have that talk over the standard Telepathy DBus interfaces to the KDE KWallet based Account Manager.
