You may be wishing there was a way to avoid typing the same information over and over and over.
You're in luck! With the Update with XML template tool, you can use an existing metadata document as a template for a new document, or to add or change sections in other documents. The beauty of this tool is that you can pick and choose which sections of the template you'd like to apply to another document, and you can update multiple documents at the same time.
Any XML document can be used as a template, but you can create and save templates containing specific sections if you like using the Metadata Template tool.
