Gaurav Kumar discusses how semantic technologies like RDF and Linked Data are being used in Drupal 7 to connect information on the web. RDF allows data to be machine-understandable and connected through a "Global Giant Graph." Drupal 7 natively supports common RDF vocabularies and allows mapping Drupal entities and attributes to RDF properties. This helps integrate Drupal data with the larger web of linked open data.
