Phase2 developed a series of modules to integrate the Calais Marmoset site crawler into Drupal. It adds a tab to the Drupal node that displays the microformat data returned my Marmoset.

This module requires that you download the Marmoset Package from http://opencalais.com/documentation/calais-marmoset. You will also have to edit some of the files according to the instructions found at http://drupal.org/node/361166.
