RSS 1.0 (note that there are a few different flavors of RSS, and not all
of them are RDF) is an RDF application.  In other words, RSS 1.0 makes
use of RDF.  The RSS 1.0 specification provides specific classes and
properties that make up an RDF model.

It's often a good idea to see if there is a particular application of
RDF that fits your needs.  RSS 1.0 might be what you need.  Because RSS
1.0 is RDF, you're allowed to extend its semantics by adding new classes
or properties as needed.

RSS is really handy to use on the web along side your XHTML version of
the article.  There are many clients out there that will consume that
RSS document and store it locally, then do any number of things with it,
usually present it to a user in some compact fashion.

So to your question of: "What happens to the old headlines?", it's up to
the client that has consumed the RSS. Typically, they will eventually be
replaced by newer headlines.  That's just typical client behavior.  A
server application that consumes RSS may keep old headlines around for a
while.

Hope that helps,
Seth
