If you want to link two attribute values so that one updates alongside the other, you can configure an AutoTask to modify one attribute with a specific value if another attribute is edited to a specific value.
<task>
<matchCriteria type="and">
<criteria name="Rights management" type="action" value="attributeChange"/>
<criteria name="Rights management" type="attribute" value="Expired"/>
</matchCriteria>
<modifications>
<modify name="Public use" type="attribute" value="No"/>
</modifications>
</task>matchCriteria
This AutoTask is triggered when the attribute Rights management is edited in any way to the value Expired.
modifications
Once the task is triggered, the attribute Public use will also change to the value No.
