Rich sentences... how can we simplify this without losing? It's a challenge, and this is definitely oversimplified. I haven't changed the actual document, for fear this may introduce error as well as oversimplification. DanC, would you be able to take over the Comm piece until EOD Friday? "XML provides a foundation of structured data for the Web. RDF (Resource Description Framework) is the first step towards the Semantic Web. The Semantic Web isn't Web2, or a forced upgrade of what we experience today. The Semantic Web is growing, evolving, through the creation of languages that make it possible to build both metadata for things on the Web, and autonomous Web programs that can transfer and make sense of that metadata. What 'making sense' of it means in practical terms could include negotiating prices, evaluating travel choices, scheduling meetings, discovering... anything! XML and RDF alone are not enough to make the Semantic Web happen - to have work happen between autonomous programs, you have to have collections of words and meanings, and the ability to make and agree on comparisons between those collections, which are called Ontologies. RDF and Ontology development is happening in W3C's Semantic Web Activity, but the early implementations we have today, those first steps, are XML applications of RDF." I'm sure I've exceeded your hype limit, Peter, but I am grateful for your efforts and corrections.
