Peter, thank you for your quick work.

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.

Janet
