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-agnostic 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.

Mandatory Readings

What this is NOT about

This initiative does not cover low level services such as

  • Bootloader,
  • Kernel,
  • System Init.

This initiative does not cover high level services such as

  • X-Window-System,
  • Window Manager,
  • Application Launcher,
  • Fancy UIs.

Low Level

Device

...

GSM

This involves three components:

  • GSM 07.10 (Multiplexing Daemon)
  • GSM 07.07 (Telephony)
  • GSM 07.05 (SMS)

Bluetooth

We base on the official Linux Bluetooth subsystem here, which is BlueZ.

Network

Options: Networkmanager or Intel Connection Manager

GPS

We base on Gypsy here.

High Level

PIM

  • intelligent storage database

Events

  • signaling events via I/O (ringing, blinking, vibrating)
  • might use fd.o notification API

Usage

  • coordinating application I/O requirements (think reference counting for I/O requirements)
  • might use fd.o policy API

Preferences

  • settings database

Context

  • Intelligent context API, integrating location as one -- among other -- sources

Tasks

What's there

  • bluez
  • gypsy
  • geoclue
  • py-odeviced
  • pygsmd
  • gsmd0710muxd
  • networkmanager or intel connection manager

What's missing

  • py-ophoned
  • pimd (GSoC 2008 project)
  • eventd
  • usaged
  • preferencesd
  • contextd
