Note: This is the (ongoing) description of the new framework architecture. See OpenmokoOldFramework for the framework architecture of 2007.1 and 2007.2
Contents |
Purposes
- Give people the infrastructure to create solid and exciting software products based on the Openmoko platform
- Support competing UIs while collaborating on developing services
- Encourage framework users (e.g. application developers) to also contribute to the framework
Requirements
- Make it simple
- Concentrate on core services
- Be programming language agnostic
- Be UI toolkit agnostic
- Try to reuse existing technologies as much as possible, but not at the cost of a bad API
How to achieve that technically
- Chose Dbus as the collaboration line. Below dbus, we can work together. Above dbus, we can differenciate.
- Expose features through dbus APIs implemented by UI and language-agnostic services (daemons).
- Optimize for Openmoko devices, but support multiple architectures and purposes through plugin interfaces and suitable hardware abstraction mechanisms.
- Be not afraid of reinventing the wheel for a wheel-barrow if all the existing wheels are made for sports cars.

What this is NOT about
This initiative does not cover low level services such as the
- Bootloader,
- Kernel,
- System Init,
This initiative does not cover high level services as the
- X-Window-System,
- Window Manager,
- Application Launcher,
