PIM Subsystem -Overview

Purpose

This -document describes storage, organisation and utility functionalities within -Symbian platform Personal Information Management (PIM) technology, as defined -by its subsystems: Application Engines and Application Services.

Key Concepts

Application -Engines - provide PIM data storage and manipulation.

Application -Services - provide a collection of utility components.

Application -Engines and Application Services enable user applications to acquire, organise, -maintain, and retrieve personal information.

Subsystem - a -cohesive group of components within a single technology.

Component - -the smallest unit of architectural significance and the finest grained unit -of description.

Architectural -Relationships

PIM Application -Services technology delivers high-level OS services for storage and -manipulation of user data (such as a collection of Calendar and Contacts items). -PIM subsystem components are part of Application Engines and Application Services. -The Symbian platform Generic Middleware layer contains the following PIM components: -Alarm Server, Time Zone Server and Help Model.

All the components -are contained between the OS Services layer and the User Interface layer.

Key -clients of these components are licensee applications that use subsystems -such as Telephony, SyncML and Messaging.

-PIM Subsystem components are part of the Application Services and Generic -Middleware layers - -

Application -Engines

Application Engines provide data storage and manipulation -for user data.

Calendar enables -management of calendar entries and provides access to calendar stores. The -CalInterimAPI library is the Calendar data store.
The Contacts -model provides a unified interface for managing contact information.

Application -Services

Application Services are used by multiple application -engines or applications running on Symbian.

Alarm -Server maintains a queue of system-wide alarms.
Calendar -Conversion converts dates between Gregorian and Chinese lunar calendar -dates for applications requiring Chinese date support.
Help -model manages a collection of files that provide context-sensitive -help information.
Notepad API is a middleware tool that you can write simple text to -and save for future reference.
The Calendar Interim Utils2 is an Organizer API that provides methods -you can use to keep track of your time. It displays the individual days of -a given time period. You can add notes and memos to these dates to organize -your schedule.
Phonebook APIs provide methods useful in creating a contacts database -and performing various operations on it. These APIs expand on the Contact -model.
Time -zone localization provides localized versions of time zone and city -names.
Time -zone server allows clients to obtain accurate conversion between any -time expressed in UTC and local time for a user's time zone.
Versit is -a set of utility classes that support the import and export of data that is -formatted according to a set of standards initially defined by the Versit -consortium.

There are no strong relationships between any of the subsystem components. -They are presented as a subsystem because they enable development of a set -of related applications.
