For many fields and field properties, the field formatter output must be altered to include the microdata properties.

Automatically placed

If a field has a property_type of 'text', 'integer', or 'decimal', attribute placement will be handled automatically by microdata module. The itemprop attribute is added to the field wrapper.

The resulting HTML looks like this:

<div class="field-item even" itemprop="jobTitle">Drupal Developer</div>
