RDF vocabulary for describing news?

What do people use to describe news articles in RDF? I'm pretty much all set
when it comes to properties for describing news metadata, but what I find
lacking is a class for news article. RSS has become too vague for this
purpose. I found http://ebiquity.umbc.edu/ontology/news.owl#News but
according to Sindice, it's not used anywhere except on ebiquity.umbc.edu.
