The Initialization plugin component defines the default Poll data in the _.xml_ file, including polls.
When the Poll Service runs, it will get values returned from the Initialization plugin component to initialize default Poll data.

The default Poll data are configured in the _{{{war:webapp/WEB-INF/conf/ksdemo/ks/services-configuration.xml}}}_ file.

In particular, when the Poll service starts, the Initialization plug-in component is called. Next, the _services-configuration.xml_ file is executed.
The component-plugin named _addInitialDefaultDataPlugin_ will refer to _org.exoplatform.poll.service.InitialDeafaultDataPlugin_ to execute some objects to create default data for the Poll application.

After the _org.exoplatform.poll.service.InitialDefaultDataPlugin_ object has been executed, the _org.exoplatform.poll.service.PollInitialData_ object will be called. It returns a polls array. The value of poll array is defined by the _org.exoplatform.poll.service.PollData_ object as below:

{code:xml}
<name>livedemo.default.configuration</name>
<description>initial data for live demo</description>
<object type="org.exoplatform.poll.service.PollInitialData">
  <field name="pollDatas">

      <value>
        <object type="org.exoplatform.poll.service.PollData">
          ....
        </object>
      </value>
    </collection>
  </field>
</object>
{code}

* A Poll includes some basic data which are defined in the _field_ tag with a specific name as below:

{code:xml}
