How to include Author's meta data in PDF?

[riosavila]

Im trying to include some authors meta data in the PDF title-page.
Specifically , say that I have this information in the YAML

author:
  - name: Fernando Rios-Avila
    email: [email protected]
    affiliations: 
        - id: levy
          name: Levy Economics Institute of Bard College
          city: Annandale-on-Hudson, NY
          country: USA   

Now Im using PDF output. When I render the page, i see my name s author of the paper, but I cant find a way to include the email or affiliation (other than typing it as "thanks"). Is there any way around it?
