How to add rel=author when you have "multiple authors" in one site? I would like to use Google rel=author meta tag, but I do have several authors writing in one site. I have a Drupal 7 site. Should I add a different authorship for each author?
How should I manage in that case?

I was planning to use meta tags module, (as explained here) but the only way it seems to modify all urls in order to affect different url with different meta tags.
ie: /authorname/title that way, with different urls I could create different meta tags.

Could that be a normal procedure? Or there´s another way to add the author´s context?
Or maybe you just should use one single author and avoid multiplying authorship altogether?

Ps. I don´t think this is a duplicated post, because this one refers about multiple authors, instead of just asking how to implement rel=author in D7.
This is simple.


Add a text field to the user profile at /admin/config/people/accounts/fields and call it Google Profile (or similar).
Go to the Metatag configuration page and look up the token for Google Profile.
Add this token to the Author Metatag for the relevent content type(s). The token for my setup is: [node:author:field_google_profile]
Have every author load their Google+ profile to this field in their user profile.


[EDIT] It's worth noting that Google no longer uses rel=author as a ranking factor, so this discussion is now purely academic.
