Assign Value Action

Specific definitions Assign Layer with two text values

The AssignValueAction assigns a specific value to the specified field, e.g., updating the copyright source with creators from Dublin Core. This requires the layer where the field is found to be assigned already, therefore combine with AssignLayerAction and/or LayerAssignedCondition.

The Business Rules are not executed in sequence. If one Business Rule assigns a Layer and another assigns the value, it may not work, as the Business Rule Engine may first try to assign the value when the Layer is not yet assigned.

Do not use this action for tags. If you try to assign a tag with this action and the tag was not found, you will get an empty value assigned, which results in a metadata validation error. For tags use Assign Tagbox Items Action.
