Where we write new code, we will use Python to implement the dbus services. The reason for that being the rapid prototyping nature of Python and the emphasis on the [[D-Bus]] APIs. Using Python, the turnaround times to experiment with APIs are incredibly faster than for using a compiled language such as C or C++.

Openmoko базируется на программной прослойке freesmartphone.org (FSO). Дистрибутив Om 2009 будет базироваться на FSO. Подробности смотрте на http://www.freesmartphone.org, http://docs.freesmartphone.org, и http://trac.freesmartphone.org. Openmoko is working on a stable system services back-end. Focus is on stable highlevel services that you can access from whatever language or UI that supports dbus. FSO is all about middleware, but if one stacks a bootloader+kernel under it and telephony applications on top, one gets a functional distribution. These are made available as FSO-image milestones.

[edit] Роль Python

Where we write new code, we will use Python to implement the dbus services. The reason for that being the rapid prototyping nature of Python and the emphasis on the D-Bus APIs. Using Python, the turnaround times to experiment with APIs are incredibly faster than for using a compiled language such as C or C++.

Once the APIs have been used by application programmers, we can start profiling and possibly reimplement some of the services with daemons written in Vala, if necessary. We might as well succeed in improving performance by using Pyrex/Cython/Ctypes to keep the benefits of Python.

[edit] Roadmap

The milestone releases are combined Openmoko Framework and Zhone releases. Remember: A feature that isn't visible, working, and tested in our framework testing application (Zhone) does not exist. Until Framework 1.0.0 (early 2009), we will not use any versioning in components. Afterwards, individual components may see individual releases.

Note: The milestones and tasks moved over to our issue tracker.
