YAML / SnakeYAML: how refer to the same object multiple times

Question

Hi all,

I am using YAML to import data into a db4o database and am wondering how I can structure my documents such that when I create an object, I can re-use that same object later on in another object. For instance, I declare a content type, and then a file after it that uses that content type.

How do I refer to that content type?

Using YAML you may represent objects of arbitrary graph-like structures. If you want to refer to the same object from different parts of a document, you need to use anchors and aliases
