Barry Talks!: Ode to RDF "Now it's my belief that we're entering the Age of Metadata (and out of the Age of Content), as it were. (Somehow that doesn't quite sound like something Gandalf would say.) We'll be innovating in ways to decorate everything from sites to Web Services to objects with descriptions, i.e., metadata. I'm beginning to think RDF is going to be a very big deal indeed."
Hmm -- okay, maybe there's something in RDF after all, if Barry is becoming a fan. imho a great place to start for all things data/metadata-related is Mastering Data Modeling: A User-Driven Approach
