Re: web to semantic web : an automated approach

Hi all,

Popular content management systems have a great role to play in
democratizing the semantic web. Some CMS like Drupal have already understood
this and are rapidly moving towards exposing their content as RDF data.
Because so many people are using, there is a great potential in implementing
some built in semantic web features, and that's what's happening with Drupal
7, which will ship with RDFa support in
core<http://buytaert.net/drupal-the-semantic-web-and-search>.
Drupal will then be part of the category A2, with more than 30 000 RDFa
enabled sites!
