Some SEOers have reported good experience with enriching their websites with the formal schema vocabulary Schema.org.
Is there any way to implement such schemas on Drupal 8 webpages?
Update - July 9 2016:
Is it true to say to most of the functionality of this module got into the Drupal 8 core via the module Aggregator 8.x.x ? I read now in the modules' page (for Drupal 7 as linked in the answer) and that's what I understood; But if it did, then when why creating a new module is on the quine? It is written there the module has not yet been ported and that's why I'm confused.
