consideration from the very early days

framework that allow all people to utilize all the
functionality of GNOME user environment.

7. General GNOME 2.0 arquitecture

8. GNOME releases

9. Normal releases
● GNOME policy is a release each 6 months
● Free Software!
● User can obtain a stable updated environment
each 6 months
● And each day if they are cutting-edge users
● Incremental updates

10. Major releases
● Done to introduce major changes.
● Can be a breakage of previous state
● History:
● 1997: GNOME project started
● 1999: GNOME 1.0 release
● 2002: GNOME 2.0 release

11. GNOME 3.0 is coming!
● Planned to March/April 2011
● More than 9 years since the last major release
● Several packages and libraries will be dropped
● Several common programs on GNOME 2.0 will
not be available
● A lot of work was done in order to provide proper
equivalent programs

12. Desktop interface

13. Gnome panel
● GNOME 2.0 uses the usual desktop metaphor
● Monitor as the user desktop
● Objects like documents and folders can be places
● Document can be opened into a window
● Represents a paper copy of the document placed
on the desktop

14. Nothing really new

15. gnome-shell
● Defining technology of GNOME 3.0 desktop
● Provides a new and innovative way to interact
with the desktop
● Take advantage of modern graphics hardware

16. Shiny future

17. Problems

18. Gnome-shell is so new...
● … that uses new and fancy technologies
● Not initially supported on the GNOME 2.0
accessibility stack
● Gnome shell developers are focusing on
gnome-shell itself
● But they have included accessibility in his roadmap

19. Solutions
● A11y community started to work in provide
gnome shell a11y support
● Cally could be used to access UI elements
● Required to screen readers
● A magnifier feature was introduced
● (Next presentation)

20. … but
● I would be really likely that accessibility support
will not be ready for GNOME 3.0
● Anyway, work will continue
● GNOME will maintain his 6 month policy, in 6
months GNOME 3.2 will be there
