10.3. Other updates

Based on the example above we present some XML fragments for different kinds of update. These include:

Addition of properties
Removal of properties
Addition of parameters to properties
Removal of parameters from properties
Changing parameter values.

The examples all start with the selection of the vevent properties element. First we have the XML for the addition of a tzid to the start date/time. Here we select the dtstart, then the parameters element then add a tzid parameter and change the value of the date and time

<ns2:properties>
  <ns2:property>
    <ns3:dtstart>
      <ns3:date-time>2011-07-18T15:00:00Z</ns3:date-time>
    </ns3:dtstart>
    <ns2:parameters>
      <ns2:add>
        <ns3:tzid>
          <ns3:text>America/New_York</ns3:text>
        </ns3:tzid>
      </ns2:add>
    </ns2:parameters>
    <ns2:change>
      <ns3:dtstart>
        <ns3:date-time>2011-07-18T11:00:00</ns3:date-time>
      </ns3:dtstart>
    </ns2:change>
  </ns2:property>
</ns2:properties>

In this example we add two categories to the event.

<ns2:properties>
  <ns2:add>
    <ns3:categories>
      <ns3:text>paper</ns3:text>
    </ns3:categories>
  </ns2:add>
  <ns2:add>
    <ns3:categories>
      <ns3:text>resources</ns3:text>
    </ns3:categories>
  </ns2:add>
</ns2:properties>

In this example we add a duration and remove the dtend.

<ns2:properties>
  <ns2:remove>
    <ns3:dtend>
      <ns3:date-time>2011-07-18T16:00:00Z</ns3:date-time>
    </ns3:dtend>
  </ns2:remove>
  <ns2:add>
    <ns3:duration>
      <ns3:duration>PT1H</ns3:duration>
    </ns3:duration>
  </ns2:add>
</ns2:properties>

In this example we change the dtstart timezone identifier.

<ns2:properties>
  <ns2:property>
    <ns3:dtstart>
      <ns3:parameters>
        <ns3:tzid>
          <ns3:text>America/New_York</ns3:text>
        </ns3:tzid>
      </ns3:parameters>
      <ns3:date-time>2011-07-18T11:00:00</ns3:date-time>
    </ns3:dtstart>
  <ns2:parameters>
    <ns2:parameter>
      <ns3:tzid>
        <ns3:text>America/New_York</ns3:text>
      </ns3:tzid>
      <ns2:change>
        <ns3:tzid>
          <ns3:text>America/Montreal</ns3:text>
        </ns3:tzid>
      </ns2:change>
    </ns2:parameter>
  </ns2:parameters>
  </ns2:property>
</ns2:properties>
