I have question and answer functionality in rails, with the answer field as a text area. When the user enters a link in the answer field, how do I display it as a link when displaying results?

Before or after you save the answer text, you can add the html for a link to any text recognized as a link, using an add-on gem. One option is rails_autolink, another is rinku.

I'm wondering if it's possible.
This is not a field available from the Facebook Graph API. You could request it on their Facebook Developer Group, although it doesn't seem like a field they would add.

<link rev="made" href="mailto:test.com">
It is a way to add semantic information to a page. In this case the email address of the maker.
The value made is not in the HTML spec as a link type, so this appears to really be informational only.
The rev attribute is supposed to be a link back to a parent page (or previous page), it is short for "reverse link".
Read about the rev attribute here and here.
In terms of SEO, I don't believe this example will make a difference.
