You can easily copy the value of one piece of metadata such as the Version Name or IPTC Caption into another tag such as the IPTC Object Name.
1. Use a Source Node to get the images.
2. Use a Text Node to retrieve the tag you want to copy.
3. Add an Action Node to set the value of the second tag, making sure that you set it to use the text passed through from the Text Node instead of a fixed value.
