Organizer API

Summary

The Qt Organizer API lets you work with personal information data like appointments, birthdays, to-do lists, and journal entries. It's primarly aimed at time based data, rather than people (Qt Contacts API) or messages (Qt Messaging API). The data model is aimed to be compatible with iCalendar.

Key features (planned)

• Create, filter, update and delete time based data:
  • Events (appointments, parties, deadlines etc)
  • Journal entries (associated with (Gregorian) dates)
  • To-do tasks
  • Also supports notes (little scraps of text you might stick to something in real life)

• Supports iCalendar recurrence model
  • Exceptions, complex rules etc (all the useless stuff that only unit tests use :)
  • (but currently not recurrence shorter than one day)

• Synchronous and asynchronous APIs
  • Clear separation of the APIs, allows developers to build applications with responsive UIs

• Multi platform support
  • Maemo 5
  • MeeGo
  • Symbian (S60 3.1 to Symbian^3)
  • KDE kcal (extended)

• Multiple calendar support
  • Different users, or different collections of events

• Flexible backend scheme
  • Allows HTTP based backends as well as local device backends.

• QML Support
  • Bindings to allow clients to access organizer functionality from QML via QtDeclarative plugins
  • Build next-generation, fluidly animated user interfaces for time-context-aware social applications

Currently not all features are implemented on all platforms, and we expect that the API will change in several areas before release, including:

• Time zone support
• All day events
• Multiple calendar support
• Reminders

Key features

• Create/Filter/Update/Delete events, todos, journals and notes
• Third-party providers can write plugins which allow access to different calendar or schedule sources (device, device clouds, online clouds, etc)

Example applications!

There are two example applications at the moment:

• calendardemo
• timescape (QML) (development continuing)

Both are simple demonstrations of slightly different features of the API. The timescape example uses QML, while the calendardemo example uses traditional Qt widgets.
