AT-SPI Re-Engineering to Dbus

This page is the top-level project management resource for re-engineering AT-SPI to use Dbus. The pros and cons of this migration has been discussed extensively by the Open A11y workgroup. This pages is not to discuss why, but only to track progress to measure completeness for success.

Reengineering Status

Component	Owner	Start	Stop	Completed	Target	Size	Notes
Remove Bonobo dependency from AT-SPI	Li Yuan	Oct 2007	unknown	0	GNOME X.Y	unknown	Depricate Bonobo dependency from AT-SPI, thus leaving just CORBA.
IDL to XML converter	unknown	unknown	unknown	0	GNOME X.Y	unknown	AT-SPI IDL is normative. Need to generate dbus stubs from the IDL.
Dbus enhancements	unknown	unknown	unknown	0	GNOME X.Y	unknown	Dbus may need extensions to support all concepts required by the a11y stack.
Dbus activation	unknown	unknown	unknown	0	GNOME X.Y	unknown	Switch from Bonobo to Dbus activation
Dbus AT-SPI registry (at-spi-registryd)	unknown	unknown	unknown	0	GNOME X.Y	unknown	Use Dbus instead of ORBit/bonobo to receive events from applications and deliver them to listening ATs.
Dbus AT-SPI implementation (libspi)	unknown	unknown	unknown	0	GNOME X.Y	unknown	Use Dbus instead of ORBit/bonobo to implement AT-SPI methods on behalf of bridged ATK applications
C AT-SPI (libcspi)	unknown	unknown	unknown	0	GNOME X.Y	unknown	C implementation of client-side AT-SPI library using Dbus.
Python AT-SPI (pyatspi)	unknown	unknown	unknown	0	GNOME X.Y	unknown	Python implementation of client-side AT-SPI library using Dbus.
Accessible Toolkit (ATK)	unknown	unknown	unknown	0	GNOME X.Y	unknown	Unknown if changes needed (e.g. message based versus object based transport, object lifecycles)
ATK for Gtk2 (gail)	unknown	unknown	unknown	0	GNOME X.Y	unknown	Unknown if changes needed (e.g. message based versus object based transport, object lifecycles)
ATK for Qt 4.3+	unknown	unknown	unknown	0	GNOME X.Y	unknown	Unknown, no implementation today?
GNOME Java Access Bridge	unknown	unknown	unknown	0	GNOME X.Y	unknown	Use Java Dbus instead of Java CORBA for transport
ATK bridge	unknown	unknown	unknown	0	GNOME X.Y	unknown	Use Dbus instead of ORBit/bonobo to start and connect ATK enabled applications to the registry
Orca	unknown	unknown	unknown	0	GNOME X.Y	unknown	Account for new pyatspi. Affects scripts and core.
LSR	unknown	unknown	unknown	0	GNOME X.Y	unknown	Account for new pyatspi. Affects Adapters and core.
Accerciser	unknown	unknown	unknown	0	GNOME X.Y	unknown	Account for new pyatspi
