<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 for Symbian OS v9.5 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 OS 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>
