@kimdurante What is the status of this?

Hi Eliot. Apologies, I thought i added this to our Metadata Analysis Document already. It's added now under a new tab called "Metadata Crosswalks." I think I'll need to update some of the new Aardvark element mappings. I'll take a look at the latest element names.

There is not a 1 to 1 mapping for every element due to them not being present in a schema or being created or autogenerated through other means.
