<section id="GUID-85D629ED-30D4-5608-A816-07BD375C6A76"><title>Calendar</title> <p> <xref href="GUID-00631ED2-1B7F-5FC4-9E81-4B6DF7946631.dita">Calendar</xref> allows a

user to store and manage a collection of calendar events and to-do items.

A calendar event represents a scheduled amount of time, such as a team meeting.

To-do items represent action-items or a task assigned to an individual. Electronic

schedule exchange is provided using the vCalendar 1.0 standard. </p> <p>The

Calendar API provides access to calendar stores, with functionality to fetch,

update, save and delete calendar entries. This functionality complies with

the standard RFC 2445, which defines a common format for openly exchanging

calendar and scheduling information across the internet. New functionality

includes: attachment support, defining geographic locations, logging, expanded

search capabilities and support for removable media. </p> </section>

<section id="GUID-5F20F757-46F6-5652-AB0F-6B22DBB61111"><title>Contacts Model</title> <p>The

Contacts Model is an engine component that provides access to contact information

stored on a Symbian device. Just like a real-world address book it stores

and organises names, telephone numbers, addresses and other details of individuals

and companies. It can be used to: </p> <ul>

<li id="GUID-2A32B258-B59F-5BA2-998A-AFEA77065C46"><p>add, delete and edit

data </p> </li>

<li id="GUID-0DF77DE5-267B-54BB-AD9F-1A05C9FCE0C5"><p>provide information

to clients </p> </li>

<li id="GUID-BD1AED25-AA07-5053-9A03-34F8863036D0"><p>sort and search contacts. </p> </li>

</ul> <p>The component provides a unified interface for accessing contact

information that is stored in the phone’s internal store or on an integrated

circuit card (such as a SIM/USIM). The data store contains a collection of

contact items. An item can be: </p> <ul>

<li id="GUID-B60D8D4A-B32A-54AC-8015-C1145BB88EE1"><p>a contact card, such

as a particular person </p> </li>

<li id="GUID-5024C061-C9B3-5C33-A1B7-65C618E393A6"><p>an own card (the phone

owner’s card) </p> </li>

<li id="GUID-B98D42E5-A5A7-5F7F-814B-DACAF67A67CB"><p>a template for creating

other contact items </p> </li>

<li id="GUID-B998990E-BA67-5941-AC5F-53D1CE949345"><p>a contact group, such

as a collection of contact cards. </p> </li>

</ul> <p>Electronic business card exchange is provided using the vCard 2.1

standard. vCard 3.0 Export for PBAP capability has been added in Symbian OS

v9.2. </p> </section>
