*** ''profiled provides a daemon and libraries to access and control profiles related data in the device. The libprofile (C) and libprofile-qt (Qt) are interfaces for the profile client to connect to the server using D-Bus. The profiled data is stored in ‘ini’ files which can be customized per different releases.''

** Proposal 1: Maemo6 NGF (non-graphic feedback)
 +
*** ''The device has functionality to alert user of a call, alarms and notification (SMS, email, chat, system update) events. Events may or may not have a graphical part and it may have different behavior depending on the system state. Example of this is receiving an SMS message when there is no other activity and SMS message during a call. NGF provides a unified API for apps to request logical events. The actions (e.g,. play/show LED+audio+vibra) are combined in NGF and consistent look&feel is provided''.

-
*  System APIs – we have gaps for time settings and alarms using timed, profiles using profiled, screen/backlight handling using MCE.

-
*  Sharing Framework – Architecture team is interested in seeing unified APIs for sharing files via BT, email, web services.

*  [[AgileBrowser|Architecture navigation tool]]: able to browse meego packages and visually see the dependencies.

MeeGo Architecture

MeeGo architecture team is responsible for defining and managing the MeeGo architecture. MeeGo architecture consists of Core OS layer and number of UX verticals on top the Core OS layer. The architecture team decides which component to use for the functionality needed in MeeGo with the objective of consistency inside the Core OS and to the applications that run above it.

Team

  • Arjan van de Ven, Chief Architect, responsible for MeeGo architecture
  • Sakari Poussa, Core OS Architect, responsible for Core OS architecture
  • Mikko Ylinen, Handset UX Architect, responsible for Handset UX architecture
  • Sunil Saxena, Core OS Architect, responsible for Core OS architecture

Communication

Process

  • Architecture team meets once a week. Currently the meetings are not public.
  • Agenda and minutes of the meetings will be posted to the meego-architecture mailing list
  • Anyone can propose topics to the architecture team agenda
  • Architecture topics can and should be discussed on meego-architecture mailing list
  • Architecture team is responsible of making the decision in case consensus is not reached

Process Improvement Topics

  • How to make the architecture meetings open. Not all the topics can be open but most can be. Examples of non-open parts includes topics which involves IPR, legal, patent, business, product or schedule sensitive material.

Documentation

  • Developer Documentation: APIs, tutorials, videos, examples ([1]), to be published soon
  • Architecture Documentation: High level architecture pictures and description ([2])
  • Developer and Subsystem Documentation: Detailed technical description of each MeeGo subsystem. Guidelines for developers working on MeeGo. (Architecture/Documentation)

Meetings

Upcoming Features

  • PIM Storage in Evolution Data Server (EDS) and email via Camel, SyncEvolution as sync engine
