Building Metadata Applications with RDF

The real test of any technology's value is what kinds of tasks are easier with it than without it. If I hear about some new technology, I'm not going to learn it and use it unless it saves me some trouble. Well, being a bit of a geek, I might play with it a bit, but I'm going to lose interest if I don't eventually see tangible proof that it either makes new things possible or old things easier.
