The upcoming Drupal 7 will have Semantic Web technology built in - any content that users create in a Drupal installation can be embedded as RDFa into a Drupal page. In other words, what Drupal 7 does is publish conventional Drupal content to the Semantic Web. This is great news for publishers who have content which want to port their content from the conventional "eye-ball Web" to the Semantic Web.
